A common network patch cable consists of eight wires with four twisted pairs. In the each side, the cable features RJ45 connectors, for instance the Enhanced Category5 (CAT5e) patch cable. It’s accustomed to develop connection with or between network devices and applications. This particular Ethernet cable is mainly used for connecting computers with devices such as routers, hubs or switches.

However, so far as the utility of a CAT5e patch cable is concerned, it is chiefly used in Ethernet connection where one should join a host of the computing devices for enhanced connectivity. In fact, this cable supports connection on some sophisticated telecommunication platforms for example ATM. High-speed data transmission is its USP also it meets the cabling requirements of most from the Ethernet environments.

One of the key reasons for the usability of this enhanced version of the CAT5 cable is it has a fair run length 100 meter that is enough for cabling in a small and medium-size Ethernet environment. Though within the recent years, CAT6 and CAT6e patch cable has been designed to offer run period of 550 meters and 1000 meters respectively, these products aren’t compatible with most of the network devices a sophisticated network uses. These are vendor-specific and also you need install just those hardware and software products which are fine with them. This unsuitability of latest category cables has occasioned such wide utilization of CAT5e patch cable which is universally accepted.

Moreover, CAT5e patch cables are available in both unshielded twisted pair (UTP) and shielded twisted pair (STP) configurations. Though it holds true the UTP patch cables are comparatively more frequent, certain specific network applications demand the STP because the later is greatly useful in preventing transmission disturbances brought on by Electro-Magnetic Interference (EMI).

Network patch cables can be found in the stranded and solid variety too. Within the former, the primary cable consists of a cluster of thin cables in a metallic jacket, while the eight wires inside the cover are solid copper wires within the later. However, both in of these categories, the wires are coupled to create four pairs. Despite the fact that each of them offer seamless link with Internet, the stranded cable includes a greater degree of usability because of its interference and noise-canceling capability. The stranded variety is preferred to the solid category also since it involves lesser amount of risk in the process of unplugging.

Crossover cable also operates as Ethernet patch cable and may connect two PCs together. While such an array of network patch cables is available in the marketplace, you have to consult a network engineer to know which will suit your Ethernet network the most.

However, apart from the common four-pair patch cable, engineers may also opt for a fiber optic patch cable. Though the utility of CAT5e network cable has never been questioned, fiber patch cables are extensively used too. This variety of patch cable is made of fiber optic material and also the connectors at the two different ends are also available in the fiber optic.

Nowadays fiber optic patch cable has started to experience an important role in completing the end-to-end connection of systems. It is used immensely for a number of purposes associated with data transmission. One of the most common uses is perfect for the change in internet signals in the source router till the computer. As a kind of beneficial network cables, fiber patch cables are very popular and used in almost all kinds of digital data transmissions.

Why are fiber patch cables beneficial? To begin with, let's make it clear what makes the optical fiber communication important. The fiber optics makes sure that certain desired properties associated with a communication are satisfied. And also the quality they maintain regarding these properties makes using these network cables desirable.

Interestingly, the fiber optic patch cables require being compatible with each one of these properties to keep up with the network quality. So the attributes desirable of the fiber cables are also good for the patches. A few of the important properties are listed below.

  • Bandwith Rate: Data of high volume may be easily transferred using the optic cables. In fact, with the mainline network cables, one can transfer terabytes of information every second as completed in case from the worldwide Internet exchange data. The same can probably be said about the fiber optic patch cables. The bandwidth of those cables is extremely high.
  • Communication Speed: The physical communication happens over modulated waves of light. Consequently, the rate of communication is extremely fast with the fiber optic networks. One can use these networks to access real time data around the world. The patch cables are compatible with the speed plus they can transfer data at the same speed as the main network cable.
  • Attenuation Absence: Attenuation of signal is really a critical factor in most of the networks. However, to have an optical network, this is practically absent. The data can traverse along the network without any amplifier installed in the path. The patch cables also do not attenuate the information.
  • Transferred Data Accuracy: The transfer of data takes place with a high degree of accuracy. The information is affected with practically no external hindrance. No signal coming form outside really changes anything about the data. As a result, the information transfer preserves the precision of information exchange. The fiber optic patch cables maintain high levels of accuracy with regards to bandwith.
  • Security Factors: Fiber optic patch cables are as secure as the overall optical fiber network. They're extremely hard to break into and therefore the potential of data leaking out of the network is virtually minimal.

The suggestions above properties result in the optical patch cords beneficial when it comes to real life application. Make sure that you have the best patch cable with the proper length and aperture, and you are in a position to enjoy the advantages of a safe and secure and high speed communication.

fiber optic patch cable

Network cable has changed over the years. As there appeared lots of innovative technologies, it is being a very high speed vehicle with large volume increased in its overall capacity to transmit and carry audio or visual data to long distances.

Since there are different kinds of network cables available, it is important to be aware of the kinds and their specific functions. Generally, there are several types of network cables which are coaxial cables, fiber optic cables, patch cables, and the twisted pair cables. These cables are extensively popular as they help in connecting different electrical devices such as connecting the personal computers to a printer or scanner. Also, there are straight cables which enable the computer to be connected to various switches and routers. Here is a summary of the three mainly used types.

  • Coaxial cable is really a network cable that keeps the whole electromagnetic wave received right within the cable itself. Thus, the wave is forced in which to stay between your conductor and also the shield. Here, there's complete transmission of information between your conductors within the cables. The controlled transmission of data within the cables makes it easy to be utilised as transmitters of signals in televisions and other associated electronic goods. The benefit with these cables is they can be simply curved, bent or even twisted without the chance of getting electrocuted.
  • Fiber optic cable is a network cable which has a minimum of two strands of optical fiber or glass. It has a plastic cover each one of these and all the covered fiber wires constructed in a safe plastic cover that is environment friendly and ensures safety from the type of harm to life or property. It is very user friendly and has higher ability to transmit light wave's higher bandwidth at long distances at a stretch. Optical cables are safer than the copper wired cables. Patch cables really are a type of optical cables with various connectors for example FC, LC, SC, ST, etc. Fiber optic patch cable is extremely beneficial in connecting telephone lines, mainly home phones over not too long distances. The variations in color help to find out the different cable wires within. For instance, patch cord LC is yellow or orange through the severance of single mode and multimode.
  • Twisted pair cable is really a network cable mainly utilised for connecting two computer related devices with easy transmit of network. It comprises of two pairs of copper wires that are twisted in pairs. The twisted pair cable is incredibly useful in connecting two computers helping to prevent any sort of cross networking or cross talk with the way it is assembled together. It is put into color casings for easy identification.

The benefit of utilising network cables is they can effectively be employed to connect devices from short distances such as the computer to numerous other relevant devices or HD TV to experience stations, or any other such modern gadget. You will find facilities to use network cables to connect long distant connections such as the internet connections that travel for extremely long distances so that anyone relaxing in any part around the globe can certainly access the internet with requisite connections like the Wi-Fi, individual internet facilities or other connection that allows accessibility internet from computers, laptops, ipad, iphone etc.

FiberStore provides the great quality network cables at the most huge discounts. There are numerous fiber patch cables such as single/multimode patch cable and MPO cable etc.

As the rapid growth and development of network, we create a lot of network application updates and upgrades almost every couple of years. Facing the situation of rising demand, fiber cabling has become the best answer.

There are lots of different parameters indicators to examine the performance of different network media. Copper networks use electrical signals, as the fiber optic networks use optical signals. Whether using electrical signals or optical signals, the insertion loss, return loss, noise and interference would be the main factors affecting network performance. Obviously, the mismatch between joints brought on by the decline in network performance can also be due to the standards mentioned above.

The major characteristics of fiber optic cable, connector, jumper, optical pigtail along with other components are relatively stable in the actual utilisation of the wiring process. Because they are relatively fixed, so the stability of the connections in patch cords (ST to ST fiber patch cable, LC to ST fiber patch cable, etc.) may technically modify the actual fiber optic network. Here’s an analysis and discussion of the optical fiber connection technology in two aspects.

  • 1. Splicing Methods: Fusion splicing has a high rate of success, however the joint after splicing is simpler to break or failure. Under normal circumstances, the splice connection loss could be smaller, generally below 0.2dB, but the return loss is difficult to control, while in the optical fiber fusion process, external factors affecting the quality of lots of splicing, for example environmental conditions, operation of proficiency, the matching of optical fiber. Machine splicing process can’t avoid too large fiber loss for individual reality. Moreover, experience tells us the real lack of worth of splicing must test in order to obtain. In the fiber core under a few more, it is easy to damage, if the test answers are not satisfactory or compliance, to be re-selected after which rework it. Following the network has been utilized , when there is have to slowly move the location to be interrupted fiber optic link, a new position in the re-splicing. The suggestions above could be the emergence of all. Let us pay a lot of splicing work and also the extra care the safety of fiber.
  • 2. Connector Access: People who involved in the manufacture and manufacture of optical products factory colleagues should be fully aware of this. On-site grinding and the factory production are the two can’t compare the way different factory is specialized grinding machine used by the coarse to fine of five grinding process, can’t adjust the pressure field can not be consistent with manual grinding. Maybe previously, the standard low speed network is acceptable, even if there’s excessive insertion loss and return loss, connection instability, etc., since the amount of fiber rich enough to absorb the impact factors. However, in today’s increasingly high end network, a lot of indicators and parameters are extremely sensitive. Because the design requirements or neglect to link effort and time, so the designer or construction are headache, loss occurs beyond the network design requirements, testing such things can’t occur.

In order to solve the optical fiber connection problems might be encountered, so that the design, construction, maintenance and employ of more reliable and stable, the German company has developed the pre-connect technology. According to the actual needs of the scene, the pre-connect technology can pick pre-terminated connectors at each side from the PE or LSZH for indoor or outdoor optical cable. Pre-cable is used for connecting private branch parts. The bare optical fiber cable in the output may become resistant pull, or compression of 3.0/2.0 cable. You’ll be able to eliminate fiber optic network design, construction and employ of various uncertain factors that may cause damage to the fiber optic link or security implications. The entire guarantee system security meets the objective of the design requirements.

Cable connection and installing of pre-construction flow chart with a number of ways of traditional fiber optic terminals compared to pre-connect technology which uses fiber optic directly, that is, pre-terminated fiber cable with no fiber connection point.

Ethernet Devices

If searching for the distinction of Ethernet over Fiber and traditional Ethernet technology, you will find stuff that one has to keep in mind. The more someone has used both the ethernet and fiber optic network services, the faster the first is capable of seeing the difference together. There has never been an occasion when Ethernet is perfect like it reaches this moment because of using fiber optics. Why? The need to increase internet speed is the major reason.

Companies and business people use Ethernet services to keep data and transfer information inside their institutions. Attaining internet speed is one of the reason everyone should upgrade their current bandwidth. With Ethernet over Fiber, there are better video and audio and data applications employed for businesses purposes such as advertising and business promotions every so often.

After using these applications for a while, you realize the rate where the transfer data from one spot to another varies. A paramount thing about this process is the notion that it allows for quick data transfer in one place to another through fiber optic cables. And between your traditional Ethernet devices and fiber optic network equipments, patch cables can be used for the bond. For instance, the SC to LC fiber patch cable is commonly utilized in the Ethernet cabling.

Ethernet over Fiber is an extremely cost effective enterprise answer and it thus becomes the business solution that everybody wants to go for. It is the best option of all the available technologies within the design and development market today. Its speed is higher, effective and efficient as compared to the traditional cables, wireless connections and also the satellites. In addition, Ethernet over Fiber can go up to around 50Mbps in the initial period, latter to 100Mbps, 1000Mbps, 10Gbps and even 100Gbps now.

In terms of holding capacities, this technology has a higher capacity different from every other type of connections. We've got the technology has the ability to carry data over a longer distance compared to traditional cables, wireless connections and the satellites. It's also lightweight, has a longer lifespan that other connections do not have and therefore, it's simpler to handle.

The other essential aspect with Ethernet services is they can work in any place anytime and therefore they are not location specific. For people, business owners and companies that are looking to determine a gradual change in data transmission speed, choosing the ethernet will allow them to see the difference.

The most important thing is that for the system to work faster and effectively, it is mandatory to achieve the right infrastructure installed. Many telecommunication and cable information mill putting this technology to make use of to enhance their services and productivity.

Fiber optic cable termination can be mainly split into two types that are factory termination and field termination. For tighter loss budget, the best approach is factory terminated cables since it is much easier to achieve low loss and quality connector terminations in a controlled factory environment. On the other hand, field terminations provide far more flexibility in meeting system requirements. As technicians face important trade-offs in deciding which method of choose, here provides a detailed comparison on merits and choices backward and forward types.

Merits Of Factory Termination And Field Termination

Advantages:

  • Factory Termination: The factory has to guarantee the quality. Fiber optic manufacturers have highly trained technicians and quality equipment for the job. Factory technicians usually are expert on fiber connector polishing plus they produce thousands of optical patch cords and fiber pigtails on a daily basis. Factory termination offers the cheapest. Since factories produce mass volume of fiber patch cords, they've reduced the price towards the most favorable point. This is actually the most economic choice.
  • Field Termination: Field termination offers the best flexibility in meeting system requirements. You can just pull the fiber cables and terminate them later. That you can do on-the-spot repairs wherever there's a defective fiber link. This is actually the biggest advantage of doing the termination yourself.

Disadvantages:

  • Factory Termination: Factory termination doesn't provide as much flexibility as field termination. You need to get the exact listing of fiber lengths and quantities and you've got to make certain that you've enough spare period of cable for every termination.
  • Field Termination: Field termination is high cost. You need some polishing tools and supplies. Field termination quality are Suitable for multimode applications, however for single mode applications, you'd better leave that to factory termination. The field termination technician must be highly skilled. He would have to practice a great deal offline before doing the actual work. A poor termination can cost you both time and money.

Choices Of Factory Termination And Field Termination

Choosing Factory Termination:

  • Factory pre-terminated cables: For this kind of business, you give a list of cable types, lengths and quantities to the factory. The factory will deliver each pre-terminated cable on the reel. You just need to pull these cables through duct carefully having a cable netting to safeguard the connectors.
  • Factory pre-terminated pigtails and splicing: This can be a intermediate approach. You order cable segments with factory-mounted connectors on one end only. You have to order some fiber pigtails and then splice the pigtail towards the unterminated end from the cable. This is a fast and simple approach. However, it takes that you curently have the fusion splicers. Or else you would need to choose the less reliable mechanical splicing.

Choosing Field Termination:

  • Field installation of epoxy and polish connectors: Plenty of experience technicians still prefer this way because it provides the best flexibility and the lowest possible cost. Epoxy and polish connectors overlap with used by factories. You pull the fiber first, after which terminate the fiber on the site. This involves fiber optic epoxy, high temperature curing oven, scribe tools, polishing films and fiber optic inspection microscopes. This method needs you have a fiber termination kit which includes these items.
  • Field installation of quick termination connectors: Quick termination connectors really are a god bless for emergency repairs. This kind of connector functions as an optical pigtail. It is pre-polished within the factory. It features a fiber stub within the connector body. You just need to cleave your fiber, insert it into the connector body, and lock it per the connector manufacturer's instruction. However, it doesn't provide just as much long-term reliability as the epoxy and polish connectors. Also, quick termination connectors are much more costly then standard epoxy and polish connectors.

Patch panel has two kinds which are wall-mounted and rack-mounted versions. As surmounting trouble rises, an optical fiber technician must choose the the most suitable patch panel for the situation. What should be recognized is which involves easy installation, proper termination and long term maintenance, because not all patch panels are made equally.

Fiber optic cable is robust and for that reason deserves some kind of special treatment. For example, if a horizontal copper cable is damaged, one user will be affected, while if a backbone fiber optic cable goes down, it will take lots of users down by using it. For this reason using fully enclosed connecting hardware (fiber optic patch panel) for optical fiber cable is crucial. And it is even the reason why technician must choose from using wall-mounted or rack-mounted hardware. The optical fiber density required will likely influence the technicians' choice between the wall-mounted and rack-mounted connectivity. As fiber patch cord types used by many technicians are various, choosing the right patch panel involves be considered a common thing.

Difference Between Wall-Mounted And Rack-Mounted Patch Panels

  • Wall-mounted patch panels are compatible with the fiber optic cable count generally as much as 24 fibers, and may extend to as many as 144 fibers through small form factors and high density connectors. Wall-mount patch panels offer the benefit of reduced space on the floor requirements.
  • Rack-mounted patch panels may be used with higher fabric counts or depending on the proximity to communications equipment where rack-mounted patch panels are preferable. 1U patch panels are designed for as much as 24 optical fiber cables with ST or SC connectors, or as much as 48 optical fibers by utilizing small form factor connectors. For extra protection, 2U to 4U patch panels can be used to handle as much as 144 optical fiber connections.

In a MPO cable, a 12 fiber MPO connector can speed installation time and increase the concentration of connection hardware. The factory terminated and tested cassettes look after breaking out the optical fibers from the MPO connectors to ST, SC, or MT-RJ connectors. The MPO cassette can double the amount concentration that is possible in rack-mount patch panels, up to 72 optical fibers in a 1U patch panel and 288 optical fibers inside a 4U patch panel, making these optical fibers perfectly fit to satisfy high density applications, such as data centers and storage space networks.

Accessibility is an issue for very long term maintenance when selecting a rack-mount patch panel. The 1U patch panels may have a an access panel to achieve the rear optical fibers, while larger patch panels could have a removable rear cover with adequate room inside to create changes or perform repairs. Strain relief and loop management for incoming cables should be provided, nonetheless management devices should be sufficiently small as to not interfere with accessibility optical fibers. Cable management for patch cords should be provided on the front of the patch panel with clear front covers and labeling arranged to ease moves, adds and changes and by ensuring that port identification is not obscured by patch cords.

Since copper patch panels need to be sufficiently strong not to flex an excessive amount of because the cables are punched down. The rolled edges around the panel sheet metal stock help to make the patch panels rigid.

Copper patch panels should provide 24 ports in a 1U height or 48 ports inside a 2U height. It is essential to make sure that the modular jacks and circuit traces on the panels are safe from debris that can short out circuits. All cable management systems must be simple to use and keep to avoid any potential problems.

Optical patch cords used as jumper cables, also called fiber optic jumpers, are often used between the optical transceiver and fiber terminal box. The main purpose of fiber optic jumpers detection is to ensure the quality of system connection, reduce the failure factors, and identify the fiber point of failure in the event of a failure. There are many detection methods which are mainly divided into artificial simple measurement and precision instruments measurement.

  • Artificial Simple Measurement: This method is generally used to rapidly detect the fiber jumpers' ON/OFF and distinguish fiber jumpers in construction. It uses a simple light source to infiltrate visible light into the fiber optic jumper from one end, and observe which one glows from the other side to achieve the detection. Although this method is simple, it can not quantitatively measure the attenuation and breakpoint of fiber optic jumpers.
  • Precision Instruments Measurement: Using the optical power meter or optical time domain reflectometer (OTDR) to quantitatively measure the fiber jumpers, the attenuation of fiber jumpers andconnectors can be measured, even the breakpoint position of fiber optic jumpers can be measured. This method can be used to quantitatively analyze the reasons of fiber optic networks' failure and evaluate optical networking products.

Fiber optic jumper is mainly used in the engine room to realize the connections between the fiber terminal and the devices, the equipment and devices, and the ports of wiring closet. It is very commonly used in fiber optic networks. We found that in network maintenance, to make a good connection between fiber optic jumpers and fiber couplers (adapters), the fiber jumpers end face's cleanliness is an important factor, which directly affects the quality of network communications.

Fiber Jumper end face means the distal section of its two connectors. It is often an easily overlooked place, because of nonstandard operation, which can easily be contaminated. In the daily operation and maintenance to the light path, operating specifications should be strictly enforced to ensure the cleanliness of fiber jumpers face. If the fiber end face is polluted, we must follow standardized procedures for cleaning. Here are how to inspect fiber end face's cleanliness and the clean-up methods.

  • Visual Inspection: Under normal circumstances the most common practice is to check the face dirt: Disconnect the device pick up the fiber jumpers against the light, by observing the side facing the bright light refraction to detect whether the end is clean and smooth. Through observation, if the end face of a smooth bright light reflection is considered relatively clean, if the side face of the light is reflected light and not too smooth, it is likely there is dirt or scratches end face of such face will seriously affect the quality of the optical transmission. Of course, with the end surface inspection apparatus can be more fully understand the details of the end surface.
  • Instrument Checks: Currently fiber end face inspection tools for instrument more, which optical fiber microscope is the most widely used professional inspection equipment. Under normal circumstances for multimode fiber-optic microscope display magnification of 200 times, while for single-mode fiber-optic microscope display magnification of 400 times. More advanced fiber-optic microscope magnification can not only switch between the two, but also through the LCD screen displays the fiber end, and thereby not disconnect the device detects the fiber end, but also to avoid the risk of eye injury by laser.

Cleaning Methods
In the fiber jumper end face inspection process, once the optical fiber end surface microscopy revealed the presence of fiber dirt, it must be properly cleaned to avoid triggering a decline in the quality of the communication problems. Each method has its own maintenance staff to do cleaning and maintenance, different cleaning methods to get different cleaning effect, if conditions permit, or the help of professional cleaning tools to help better. The importance of clean face a lot of companies now have noticed, and develop a variety of face cleaning tools, the author will introduce the following tools to assist in a professional and non-professional tools assisted two end cleaning methods.

In the absence of tools to assist in the case need to prepare ethanol, clean cotton balls, lens paper. Cleaning procedure is as follows.

  • 1) Clean cotton ball in one hand, and then ethanol drops on cotton balls, alcohol should not drop too much.
  • 2) With an anhydrous alcohol with a cotton wipe face along the same direction, the number of dirt under the end of the product.
  • 3) Put a good face with an alcohol wipe three or more layers of the folded lens paper to wipe face in the same direction until the alcohol is completely dry and the end face of the light reflection of bright reflective so far.
  • 4) Carefully examine each end to reflect the circumstances and phototabdus whether the fiber end face of residual debris and, if necessary, repeat the above steps 1-3 until the end clean flawless so far.

In the cleaning process should use the right cleaning tools and cleaning steps if incorrect cleaning methods not only face clean ineffective, but also may cause permanent damage to the face. After cleaning, be sure to check again and then insert the connector end to ensure that contaminants have been completely removed. If necessary, you will need to be cleaned again again, in order to ensure complete removal of the first failed to clear the dirt, so that the end to keep clean.

The above talking about fiber jumpers end face inspection and cleaning methods are simple and feasible, but in the usual course of operation and maintenance we should enhance the awareness of this aspect's cleaning. Because dust and oil will damage the fiber coupling, when the fiber jumpers are not in use, we must use protective sleeve to protecte the fiber optic connector, as well as to fiber couplers. Every time before the use of fiber jumpers we should clean the end face using a fiber paper. With cleaning consciousness, we can effectively reduce the fiber jumpers failures, and improve the quality of fiber optic lines and maintenance efficiency.

Generally in the network cabling, outdoors (connection between buildings) use fiber optic cables, while indoors (inside buildings) use Ethernet twisted pair cables. Then how to convert the transmission media between the Outdoor Optical Network and the Indoor Ethernet Network?

And what devices are used in the connection? What roles do they play? How about the relationship between them? The answers are as following. Firstly, the mainly used devices are fiber terminal box, fiber optic patch cable, fiber optic pigtail and optical transceiver module etc.

Connection Relationship:

  • Step 1: Access outdoor fiber optic cables into fiber terminal box for the purpose of splicing the optical fiber cable and fiber optic pigtail, leading out it by using fiber optic patch cable.
  • Step 2: Access the fiber patch cable into fiber transceivers to convert optical signals into electrical signals.
  • Step 3: Electrical signal sent by the fiber transceivers uses the transmission medium of twisted pair. At this point UTP network devices can be connected to RJ-45 connectors. So far, the conversion of optical signals is completed.

Tips: There are many network devices which have optical ports, but if there is no optical modules (similar to the fiber optic transceiver functions), the ports can not be used.

Fiber Terminal Box is a terminal protection box for the splicing of fiber optic cable and pigtail. Fiber optic terminal box is a cable end fitting. Its two ends are fiber optic cables and pigtails, the equivalent is to be split into a single fiber optic cable equipment. Fiber terminal box is used to terminate fiber optic cable, and connect the core to pigtails. The access fiber cable can have multi cores, for example, a 4-core cable (cable has four cores), through terminal box, you can splice this optical cable to a maximum of four pigtails, that leads out of 4 fiber patch cables.

Optical Pigtail: connector at one end and the other end is a cable core breakage. By welding, is connected with the other cable core. Also known as swine pigtail cable terminal box to the device that is used for the connection between the optical fiber. Often divided into single-mode or multi-mode fiber pigtail, single fiber or dual fiber, transmission distance, as well as pigtail interface type. Commonly used in fiber optic devices currently on the market pigtail interface types are generally: FC, SC, LC, ST these four.

The role of fiber pigtail is mainly used to connect both ends of the connector, pigtail splicing fiber optic connectors at one end with the other end through a special connector (FC, SC, LC, ST) with fiber-optic transceiver or optical module is connected, constituting the optical data transmission path. Where FC and FC connectors generally used in communications transmission equipment; ST connectors are generally the first coupler adapter, and then connect to fiber optic transceiver modules.

Usually there are no pure fiber optic pigtails on sale (FIBERSTORE can supply), but we can cut the fiber patch cable from the middle, it then becomes two fiber pigtails. Pigtails for use in terminal box, connect the fiber optic cable through the terminal box coupler (adapter) to connect pigtails and fiber patch cables.

Fiber Optic Patch Cable: Its two ends are both active joints. It is used for connecting fiber optic pigtails and devices. It has thick protective layer, and is commonly used in the connection between optical transceiver and fiber terminal box. It is also called fiber jumper or fiber optic patch cord.

Fiber splice tray is used for abutting joint a two fiber optic cables into a long one. They are not interchangeable between, fiber optic cable and optical transceiver is connected via fiber optic terminal box, that is, can only be inserted on optical pigtail. Fiber terminal box and splice tray can be understood as: in which the optical fiber splice two heads, but the former is a fiber optic cable and pigtail splice, which is a fusion between cable.

Fiber optic closure and fiber terminal box are not the same. Fiber optic closure is fully sealed, waterproof but it can not fix pigtails; fiber terminal box is not waterproof, while the internal structure can fix fiber optic cables, pigtail coupler can be fixed while only connecting two pigtails and sub ​​SC/PC FC/PC interfaces, which is between fiber optic cables and pigtails spliced by splicing machines.

What is the difference between the fiber patch cable and fiber optic pigtail? Can the fiber patch cable be divided into two fiber pigtails? Only one end of fiber pigtail is an active connector, while fiber patch cables have active joints on both ends. There are many different interfaces require different couplers. Fiber patch cables can be used as a divided two pigtails with.
