Product overview
The Flashlink CWDM (Coarse Wavelength Division Multiplexing) system is based on all-
optical modules for multiplexing and demultiplexing 8 CWDM wavelengths according to
ITU-T G.694.2. Two sets of wavelengths, one from 1470 to 1610nm (1-8) and one from
1270 to 1410nm with an upgrade port. By use of the upgrade port, up to 16 optical signals
can be run over a single fibre. 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. The units
can be cascaded through the upgrade ports in the 9-16 module.
