CWDM

CWDM stands for Coarse Wavelength Division Multiplexing. The CWDM technology allows a high number of simultaneous wavelengths (channels) to travel over the same optic fiber, thus enhancing the capacity of the fiber. The combination is possible by using passive optical filters (mux/demuxes). There are currently 18 CWDM channels available for single-mode fiber only. Channel wavelengths are starting at 1271nm and go in steps of 20nm up to 1611nm. Mostly used are the 8 channels 1471nm to 1611nm. All CWDM 10G transceivers have Digital Diagnostic and Monitoring features built-in. We have transceivers available for all other CWDM channels (1271nm to 1451nm), please contact us for availability.
