CWDM Module |
|
|
We coarse wavelength division multiplexer(CWDM)modules with epoxy-free optical path have low insertion loss, low PDL, high channel isolation, high stability and reliability. They can be sued for optical networks, telecommunication systems, WDM systems, FTTx and CATV. Our CWDM modules are cascaded with 3p OADM components manufactured by thin-film technology. These will be a powerful solution for the market demand of cost-effective system
