CWDM Filters
Coarse Wave Division Multiplexing (CWDM) has gained prevalence in multi-wavelength
digital transport architectures because it enables the use of very low cost un-cooled DFB
laser transmitters. Moreover, powering requirements are reduced and reliability is
increased.

CWDM filters provide the essential wavelength muxing/demuxing in these systems.
Configurations of 1, 4, 8 or 10 channels are available to provide maximum design flexibility. The
single channel version can be ordered in any of the 10 standard ITU-grid wavelengths and
functions as Optical Add-Drop Mux (OADM). The 4, 8 and 10 channel versions are designed for
minimum flat insertion loss.
