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.
Low Insertion Loss Wide pass band
High channel High stability and reliability
Epoxy free on optical path
Line monitoring WDM network
Telecommunication Cellular application
Fiber optical amplifier Access network
