CWDM can realize the multiplexing and demultiplexing between two communication channel .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.
• Low PDL
• Low insertion loss
• High channel isolation
• Excellent environmental reliability
