2.3 SFP Fiber Optics
A gigabit interface converter (SFP) is a transceiver that converts electric currents (digital highs and lows) to optical signals, and
optical signals to digital electric currents. The SFP is typically employed in fiber optic and Ethernet systems as an interface for
high-speed networking. The data transfer rate is 1.25 gigabit per second.
SFP modules allow technicians to easily configure and upgrade electro-optical communications networks. The typical SFP
transceiver is a plug-in module that supports hot-plugging (it can be removed and replaced without turning off the system). The
devices are economical, because they eliminate the necessity for replacing entire boards at the system level. Upgrading can be
done with any number of units at a time, from an individual module to all the modules in a system. SFP (Small Form Pluggable
Transceivers), meet the Gigabit Interface Converter specification Rev. 5.4 (MOD_DEF4) industry standard.
