HOME Products WDM Module


CWDM(Coarse Wavelength Division Multiplexer) is expanding the bandwidth of Metro / Access
communication networks. Our CWDM is based on thin film filter technology and metal bonding micro
optics packaging. We provides high quality CWDM with flat channel bandwidth, flexible channel
configuration, low insertion loss and high isolation.
