CWDM and DWDM solutions are known for their ability to share a single physical fiber optic circuit for several optical connections, thus extending the bandwidth of fiber and allow multiple applications to run over same resources.
The CWDM spectrum includes up to 18 channels and it can co-exist with DWDM spectrum which, for a 100GHz grid offers up to 60 separate channels for fiber communications. We do provide a large selection of CWDM and DWDM mux/demuxes (filters) with usually 4, 8 or 16 channels, but we also are able to execute by order ANY configuration of CWDM or DWDM mux/demux.

CWDM and DWDM filters are passive fiber devices that split the common fiber into different channels. We do custom filters covering all 18 CWDM channels and all 60 DWDM ITU channels. We also offer various casings for such filters: small form, desk, rack19"
