Description
We provide CWDM module, including CWDM mux / demux module and CWDM
OADM module. Single fiber or dual fiber connection for CWDM
mux/demux can be applicable.
Our 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. 4 channel, 6
channel, 8 channel, 16 channel, 18 channel can be chosen.
Features
Low insertion loss
Wide pass band
High channel isolation
High stability and reliability
Epoxy free on optical path
Applications
Line monitoring
WDM network
Telecommunication
Cellular Application
Fiber optical amplifier
