CWDM can be applied to metropolis and Metropolitan Area Network, at the same time it can be applied to City core networks which is great promise in practice. The CWDM is an extension of the Optical Metropolitan Area Network product family. Cable operators and other service providers can utilize the CWDM in outdoor environments to aggregate, over a single fiber pair, multiple private CWDM optical channels originating from multiple customer premises. Operators can also place it in the basement of a multi-tenant building to service multiple end customers with fully private, multi-protocol, optical wavelength services.CWDM can be used in 4/8 in 1 multiplexing fiber-link, replacing equipment attached to optical fiber cable and increasing efficiency of bandwidth with low cost. It is applied to construct Metropolitan Area Network, especially inconvenience in laying fiberleased wirelack of fiber resource and some other operators need increase efficiency of bandwidth. The equipment is exploited by using CWDM technology, multiplexing multi-ray channel whose wavelength interval is 20 nm on one or a pair of fiber to transmission. It can be applied to some occasion ,such as point to pointpoint to multi-pointfast optical multiplexingmovable collocate optical multiplexing. The technology is mature and the cost is low, can reduce the invested capital of building Metropolitan Area Network and extending capacity, so, it is super in competition. The equipment can be applied to service transmission abroad, such as core networkverge networkaccess network in SDHSONETEthernetATM and optical Metropolitan Area Network.
