PWDM is used for packaging of optical module. It can realize the multiplexing of two communication signal, which expands the capacity of single fiber and achieves bi-directional communication. It is widely used in optical network upgrade and expansion, or introduce new comprehensive business (CATV, TELECOM, integration of three networks-PON+EOC) etc.
