1.25G/2.5G CWDM equipment 2-8wave band CWDM  Equipment Coarse Wavelength Division Multiplexer

Product Introduction 

As information Technology Development, especially, high-speed increase of INTERNET  IP  data service, the requirement of transmission line bandwidth has constantly increased. WDM  technology as a most effective way 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 construction of citywide LAN.

 Wavelength Division Multiplexing system (WDM) can conserve fiber resources and reduce networking cost. It has solve the problem of lack of fiber and Multi-Service transparent transmission. Be used in MANs assemblage and access layer. Realize construct network and develop operation in short time. OCDA possess advantages 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
