Huashu’s CWDM devices and modules are based on Thin-film filter technology, with improved performance like low insertion loss, low crosstalk, and band width high isolation, which can be used to establish a low cost bi-directional optical communication system. Standard CWDM wavelength (from 1270nm to 1610nm in 20nm spacing) defined by the ITU G.694.2 can be provided; also full 18-wavelength is available with low insertion loss and high reliabilities.
 

Features

• Low insertion loss
• Low PDL
• High channel isolation
• Excellent environmental reliability

Applications

• WDM system
• CATV

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.
