CWDM ITU Component
Description
Hangsen Star’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, HSS’s CWDMs can be configured from a
standard list of packaging and connector options
Features
Low Insertion Loss，Low PDL
High channel isolation
Exceptional reliability and stability
Wide Operating Wavelength
Wide Operating Temperature
Applications
Access networks，Metro WDM Systems，Enterprise networks，Fiber optic instruments
