for Supervisory

Channel Applications

Description

The laser module is intended as a source for an optical supervisory
channel for systems with in-line amplifiers as proposed by ITU-T in
G.691 and G692. The module includes an InGaAs/InP DFB laser diode,
an InGaAs PIN back facet monitor diode and a TEC.
