The Coarse Wavelength Division Multiplexing (CWDM) devices utilize thin-film filter technology and are available in various wavelength combinations based on the entire wavelength spectrum (1270nm~1610nm in 20nm increments) defined by the ITU G.694.2 CWDM standard.
CWDM MODULE
Compact modules are also available with low insertion loss, low crosstalk, and wide passband with high isolation, which enables users to establish a low cost bi-directional optical communication system.
