1. General
SLW4470-xx/RH2-xnnnx Series are 1.27µm-1.61µm InGaAsP/InP MQW-DFB laser diode modules
designed for wireless communication systems.
These modules are ideally suitable for CWDM of optical microwave transmission applications.
A laser diode is mounted into a coaxial package integrated with a single mode fiber pigtail, a double-
stage isolator (lead content is less than 1000ppm) and an InGaAs monitor PD.
