The CWDM coarse multiplexing demultiplexer uses a DFB laser and does not require a refrigeration process. The CWDM devise features in small size, light weight, low power consumption and flexible and convenient to install. It is mainly used in the MAN backbone layer, MAN convergence layer, and MAN access layer.
