      CWDM Coarse Wavelength Division Multiplexing

      CWDM product is developed based on Coarse Wavelength Division Multiplexing technology and make 20nm for the wavelength interval,then transmit optical signal from multi-fiber through optical multiplexer multiplexed onto a single fiber at receiver side, different wavelength optical signals are decoded by the optical demultiplexer.


      Product introduction


      CWDM product is developed based on Coarse Wavelength Division Multiplexing technology and make 20nm for the wavelength interval,then transmit optical signal from multi-fiber through optical multiplexer multiplexed onto a single fiber

      at receiver side, different wavelength optical signals are decoded by the optical demultiplexer ,then multiplex them to a different fiber  respectively. It can Improve the communication capacity and extend bandwidth for the existing optical network,also solve the problem of insufficient Cable resources  effectively, Thus provide a simple, flexible, low-cost solution for metro access.



      Features


      • Big capacity: The DWDM single channel speed may reach 10G, the aggregate capacity may reach the 480G, C+L section can be  expand to 1600G ;

      • Flexible device networking: point-to-point, point to multipoint, chains, rings and other network topologies;Many businesses can be access flexibly and limpidly: supports ETH, PDH, SDH, CATV、 Private networkand other services;

      • Powerful network management: support of SNMP-based, CLI, WEB, TELNET and other network management;

      • Open system architecture: support for device interconnection in the different factory, single mode, multimode and electrical port can be optioned in the client side
