1. A network device comprising:
a network device chassis including:
a circuit for performing data plane switching functions;
at least one laser configured to produce an optical signal;
an integrated silicon optical components unit configured to receive the optical signal from the at least one laser; and
at least one socket; and
at least one pluggable semiconductor optical amplifier (SOA) received within the at least one socket, the at least one pluggable SOA configured to receive the optical signal from the integrated silicon optical components unit,
wherein an optical fiber is coupled to an output of the at least one pluggable SOA, and
further wherein the at least one SOA increases a power level of the optical signal entering the optical fiber.
