Technical Requirements for Coarse Wavelength Division Multiplexers
CWDM was standardized by the ITU-T G. 2 based on a grid or wavelength separation of 20 nm in the range of 1270-1610 nm. Corning coarse wavelength division multiplexing (CWDM) solutions utilize advanced thin-film-filter technology. CWDM solutions are available in industry-standard 20 nm spacing with options for a 1310 nm RF overlay bypass as well as single or bidirectional test ports. Dense WDM (DWDM) uses the C-Band (1530 nm-1565 nm) transmission window but with denser channel spacing. This capability enhances system design flexibility and efficiency, making CWDM a valuable technology in modern broadcast and production environments. This proven technology offers wide channel bandwidth, flexible channel configuration, low insertion loss, and high isolation.
