1 Product overview
CWDM1-8 and CWDM9-16 can be used to transport up to 16 signals on one single mode
fiber. The CWDM filter is bitrate and format transparent, meaning SDI, Ethernet and
SDH/SONET can run independently on separate wavelengths. The Flashlink CWDM (Coarse
Wavelength Division Multiplexing) system is based on all-optical modules for multiplexing
and de-multiplexing 8 CWDM wavelengths according to ITU-T G.694.2. The CWDM filter
come in two different version, one from 1471 to 1611nm (1-8) and one from 1271 to 1411nm
(9-16) with an upgrade port. The upgrade port can transport 16 optical signals over one
single mode fiber. The units are passive and all-optical devices, requiring no power supply or
control. Any number of channels can be used to transport signals in one direction with the
rest of the channels transporting signals in the other direction.
