Wavelength Division Multiplexing system (WDM) can conserve fiber and reduce networking cost. It has solve the of lack of fiber and Multi-Service transparent transmission. Be used in MANs and access layer. Realize construct network and develop operation in short time. OCDA possess s of low cost, low power consumption and small size, now it has been used in citywide LAN widely. Now we have developed active CWDM equipment that can run over G.652,G.653, G.655 fiber
