CWDM DEVICE

HUA-NET Coarse wavelength division multiplexer (CWDM) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provideslow insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.

Features:

 Low insertion loss
Wide pass band
High Channel Isolation
High Stability and reliability
Epoxy-free on Optical Path
