Description
LUCHUAN’s Coarse Wavelength Division Multiplexer (CWDM) devices demonstrate low loss and reliable performances.
These devices show broad passband and
high isolation, making them ideal for operation with inexpensive, uncooled
lasers. They are low cost products for the CATV and metro/access markets.
Easily customizable, LUCHUAN CWDMs can
be configured from a standard list of packaging and connector options.
