Q&A

--------------------------------------------------------------------------------------------------------------

Q: What is the SFP transceiver?

 

A: The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications.

 

SFP Transceiver Module can be regarded as the upgrade version GBIC, unlike GBIC with SC fiber optic interfaces is with LC interface and the main body size of SFP is only about half of GBIC, which makes SFP space saving, and it interfaces a network device mother board (for a router, switch, media converter or similar device) to a fiber optic or copper networking cable.

 

It is a popular industry format supported by many network component vendors. SFP transceivers module are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.
