Small form-factor pluggable optical transceiver module
The small form-factor pluggable (SFP) optical transceiver module is a fiber
optical unit that interfaces between each optical module socket (port) on the
faceplate of a function processor (FP) card and the fiber optical cables with LC
small form connectors. When FPs have SFP modules, each port can have a
different version of the module such that various multimode (MM) and single-
mode (SM) fiber cables and reaches can be appropriately connected to the
same faceplate. SFP modules provide flexible use of an FP’s interfaces for
each port on the card.
