Wavelength Division Multiplexers
Coarse WDMs
CWDM Mux/Demux Module
(4, 8, 16, 18 - Channel)
Description
Coarse wavelength division multiplexer (CWDM Mux/Demux) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides low insertion loss, high channel isolation, wide pass band, low-temperature sensitivity, and epoxy free optical path.
Features
* High isolation
* Low insertion loss
* Low polarization sensitivity
* Wide passband
* Excellent stability and reliability
* Epoxy free on the optical path
Applications
* WDM systems for metro/access network
* Telecommunications
* Optical add/Drop multiplexing
* Network monitoring
