1 Product overview
The Flashlink DWDM-8C is a set of optical modules for multiplexing and demultiplexing
100GHz spaced DWDM (Dense Wavelength Division Multiplexed) signals. The
modules are divided into multiplexers and de-multiplexers, which form a complimentary
pair. There are a total of 5 different pairs, each with their own set of wavelengths and
an upgrade port. By use of the upgrade port, up to 40 optical signals can be run over a
single 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. The units can be
cascaded through the upgrade ports in any order. However, one end should be
cascaded in opposite order compared to the other, for optimum performance.
