WDM Module PWDM Module Passive Optics
PWDM-T1550R1310/1490 is used for packaging of optical module. It can realize the multiplexing of two communication signal 1550 and 1490/1310, 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 ( VATV, TELECOM, integration of three networks-PON+EOC)etc.
