CWDM 1, 2 Channel Optical Add/Drop Multiplexer

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