1. General
SLT4460-xx/RH2-xnnnx Series are 1.27µm~1.61µm InGaAsP/InP MQW-DFB laser diode modules
designed for fiber optic communication systems. These modules are ideally suitable for CWDM of
622Mb/s or 2.5Gb/s transmission applications.
A laser diode is mounted into a coaxial package integrated with an InGaAs monitor PD, a single mode
fiber pigtail and a single-stage isolator. The lead content of this isolator is less than 1000ppm.
