CWDM Equipment

As information Technology Development, especially, high-speed increase of INTERNET  IP   service, the requirement of transmission line bandwidth has increased. WDM  technology as a in bandwidth Growth, it has been used in long-distance backbone network widely. Now the bandwidth bottlenecks has been shifted to citywide LAN. so the Wavelength Division Multiplexing system (WDM) technic is being taken more seriously in of citywide LAN.
 

 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
