CWDMG_48CH Datasheet, PDF (1/2 Pages) OPLINK Communications Inc. – Oplink’s Coarse Wavelength Division Multiplexer is based on patented athermal platform for optical device.

Coarse Wavelength Division Multiplexer
CWDMG 4/8ch Series
Oplink’s Coarse Wavelength Division Multiplexer is based on patented athermal plat-
form for optical device.This multiplexer features ultra low insertion loss, super ther-
mal stability, and unparallel reliability.The technology is a lead-free packaging platform
and no epoxy in the optical path. Green CWDM is Telcordia GR-1221and GR-1209
tested, qualified for uncontrolled environment applications and complied with industry
green initiatives such as RoHS and WEEE.
Oplink can provide customized designs to meet specialized feature applications. Also,
Oplink offers modular assemblies that integrate other components to form full func-
tioned module or subsystem.
