With the rapid growth of IP service, the demand for bandwidth of transmission lines increases continuously. Though DWDM (Dense Wavelength Division Multiplexing) technology services as the most effective solution for expansion of bandwidth, CWDM technology has advantages over the DWDM technology in terms of system costs, performance, maintenance, etc.

Based on the market demand, fiber optic manufacturers developed CWDM equipments for applications in optical fibers G.652、G.653、G.655. They are the ideal choice for increasing MAN (Metropolitan Area Network) networking. Consideration of the capacity expansion of the equipments, CWDM&DWDM mixed equipments have a strong  wave channel upgrading ability, which are the favorable choice in optimizing the network of the communication operators, reconstructing large customers network,and solving the short supply of the fiber service.
