1. Communication equipment circuitry for a communication device interfacing a Passive Optical Network PON having a first network and a second network, comprising:
a plurality of Small Form-factor Pluggable SFP port connectors each adapted to receive a Small Form-factor Pluggable SFP variant device and connect to at least a single fiber optic cable interface;
a plurality of input differential amplifiers;
a plurality of multiplexer switches; and
a plurality output differential amplifiers;
wherein the circuitry defines a plurality of differential signal paths between the plurality of Small Form-factor Pluggable SFP port connectors;
wherein the plurality of multiplexer switches are selective determinative of the differential signal paths between an input path of each Small Form-factor Pluggable SFP port connector and an output path of each of at least two other Small Form-factor Pluggable SFP port connectors through one input differential amplifiers, and simultaneously two multiplexer switches and two output differential amplifiers.
