SFPs – the small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. SFP modules are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Most SFP transceivers are used for Gigabit Ethernet and come in a wide variety of transmitters/receivers for different distances and fiber types as well as conversion to RJ-45 (copper). Eoptolink SFP optics are compliant with MSA SFP specification. SFP if the next generation of GBIC and about half the size of the GBIC.
