A SFP transceiver module is usually hot-plug I/O equipment and can be plug easily into a module socket. This transceiver efficiently connects the electrical circuitry of the module to the copper or optical network. Users are able to make use of any mix of the SFP transceiver modules that the Cisco transceiver equipment supports. The essential thing to be noted here is that each port must match the wavelength needs on the other end of the cable and also that the cable must not surpass the respective cable length that would assure reliable communication.

Users are advised to make use of the Cisco SFP transceiver modules specifically to the Cisco instrument. Each SFP transceiver module helps in the Cisco quality identification that further makes it possible for a Cisco router or switch to recognize and confirm that the transceiver module is assessed, reviewed and finally approved by Cisco.

Along with a GBIC module the fiber optic system and the Ethernet system exchange signals. GBIC means gigabit interface converter. A transceiver connects the network and fiber optic patch cords. On most cases this model is categorized depending on the optical power and cost.

Recently, there are manufacturers that have made significant advancements in the segment of fiber networks sending data. These transceivers are able to transform the incoming and outgoing electrical signals. In addition to that, the industry also established a multi-source accord for a greater united technology. Simultaneously, there are fixed specifications for the modules that are lesser in size but higher in speed than the previous versions. Hence, before investing in one such transceiver, it is important that the users update themselves about this technology.

SFP is the updated version of GBIC transceiver the full form of which is a small form factor plug. They use the small types of fiber interface and the body is much smaller than the conventional GBIC. The transmission rates for the SFP modules range from approximately 100 mbps to 4 +gbps. The transmission is possible from 500 meters to about 120 + kilometers. In addition to that, the modules are hot plug which makes them alter quick. At the same time, they are easy to maintain.
