Decriptions
1490/1310, 1550nm FWDM can realize the multiplexing and demultiplexing between 1490/1310 and 1550. It can expand the capacity of single fiber to achieve bidirectional communication, which can widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
Features:
♦ Low insertion loss
♦ Low PDL
♦ High channel isolation
♦ Excellent environmental reliability
Application:
♦ WDM system
♦ CATV
