Fiber media converters are used in networking more and more nowadays. Not the same as ordinary media converters, Fiber Media Converter is definitely an optical converter designed for the fiber optic area.

A fiber optic media converter is a simple networking device which makes it easy to connect two dissimilar media types such as twisted pair with fiber optic cabling. They were brought to the industry nearly 2 decades ago, and are essential in interconnecting fiber optic cabling-based systems with existing copper-based, structured cabling systems. They are also utilized in metropolitan area network (MAN) access and knowledge transport services to enterprise customers.

Fiber media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fiber optics. Media converter types vary from small standalone devices and PC card converters to high port-density chassis systems that offer many advanced features for network management.

On some devices, Simple Network Management Protocol (SNMP) enables proactive management of link status, monitoring chassis environmental statistics and sending traps to network managers in the event of a fiber break or perhaps link loss around the copper port.

Fiber media converters can connect different lan (LAN) media, modifying duplex and speed settings. Switching media converters can connect legacy 10BASE-T network segments to newer 100BASE-TX or 100BASE-FX Fast Ethernet infrastructure. For instance, existing half-duplex hubs could be linked to 100BASE-TX Fast Ethernet network segments over 100BASE-FX fiber.

When expanding the reach from the LAN to span multiple locations, media converters are useful in connecting multiple LANs to create one large campus area network that spans on the limited geographic area. As premises networks are primarily copper-based, fiber converter can extend the reach of the LAN over single-mode fiber up to 130 kilometers with 1550 nm optics.

Wavelength-division multiplexing (WDM) technology in the LAN is especially beneficial in situations where fiber is in limited supply or expensive to provision. As well as conventional dual strand fiber converters, with separate receive and transmit ports, there are also single strand fiber converters, which could extend full-duplex data transmission up to 70 kilometers over one optical fiber.

The benefits of media conversion include providing a gradual migration path from copper to fiber. Fiber connections can reduce electromagnetic interference.Also, fiber media converters pose like a cheap solution for those who want to buy switches for use with fiber but don’t have the funds to pay for them, they are able to buy ordinary switches and use fiber media converters to make use of with their fiber optic network.

Within the optical communication marketplace, there are several sorts of fiber optic transceivers which are SFP, GBIC, X2 and so on. Cisco is really a brand that has great overall performance on fiber optic products.

As among the fundamental fiber optic transceivers, Cisco SFP is generally utilized in many locations. The inexpensive price and the higher performance, would be the benefits of Cisco SFP. As all recognized, the little form-factor pluggable (SFP) is really a compact, hot-pluggable transceiver utilized for each telecommunication and data communications applications. The type aspect and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It’s a popular industry format jointly created and supported by many network component vendors. Cisco SFP transceivers are designed to assistance SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Because of its smaller sized size, Cisco SFP obsoletes the formerly ubiquitous gigabit interface converter (GBIC); the SFP is sometimes referred to as a Mini-GBIC although no device with this name has ever been defined within the MSAs.

So what’s GBIC? From the above paragraph we have known that GBIC is short for gigabit interface converter, which is a standard for transceivers, generally used with Gigabit Ethernet and fibre channel within the 1990s. By providing a regular, hot swappable electrical interface, 1 gigabit port can assistance a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of a huge selection of kilometers. Cisco GBIC is really a transceiver that converts serial electric signals to serial optical signals and vice versa. In networking, a GBIC is utilized to interface a fiber optic system with an Ethernet method, such as Fibre Channel and Gigabit Ethernet. Cisco GBIC enables designers to design one kind of device that can be adapted for either optical or copper applications. Cisco GBICs also are hot-swappable, which adds towards the ease of upgrading electro-optical communication networks.

To supply larger capacity, we require a Cisco X2 transceiver. Cisco X2 transceiver will be the 10G fiber optic transceiver, whose improvement was primarily based on former XENPAK standards. Cisco X2 10GB transceiver inner function is almost similar with XENPAK, and X2 also can use one transceiver to fulfill all 10G Ethernet optical port function. Cisco X2 transceiver is about half size of Xenpak, this enable it suit for density installations. Cisco X2-10GB-SR is one of the most well-liked Cisco X2 transceivers. Cisco X2-10GB-SR module is really a multimode transceiver target in the 10G applications. It works with 850nm multimode fiber and also the optical interface is duplex SC. Cisco X2-10GB-SR modules can hyperlink the equipment to fiber optic networks, max transmission distance is 300 meters and support a hyperlink of max 300 meters via multimode fiber. It is utilized in 10Gigabit applications including Ethernet and Fibre channel.

Except SFP, GBIC, X2, there are aslo other Cisco fiber optic transceivers with various use. Such as XENPAK transceiver which we’ve refered within the introduction of Cisco X2. For more information, you are able to go to FiberStore, who’s the very best fiber optic products supplier from China.
