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.
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
