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.
The range also features a filter pair setup optimized for putting 16 wavelengths onto a CWDM 1550nm wavelength. This is enabled thru the DWDM-8C-2-mkII + DWDM-8C-13mkII that covers the channel range from ch.25 – ch.40 which all fits inside the 1550nm port of Nevions CWDM filters. This is useful to extend number of signals in CWDM setups for short reach.
Note – the product is always sold and shipped as a matched pair.
