8 Channel Passive CWDM Mux Demux Access Module
By using passive multiplexers, several optical channels of different wavelengths can be combined, which will allow multiple services to the transmitted together via fiber without interference. What makes this possible is the fact that different light colours (wavelengths) do not affect each other. For transmission, light colours are multiplexed onto an fiber using a wavelength-specific filter (multiplexing). At the other (receiving) end of the line, the wavelengths are divided again, or rather, demultiplexed. Hence, any transmission line consists of a multiplexer and a demultiplexer.
The passive multiplexer and demultiplexer modules are working with the CWDM grid according ITU G.694.2 standard. The multiplexer/demultiplexer rack modules are part of a wide product range of functional modules for installation in modular rack systems from MICROSENS. In addition to desktop housings, users can select a 19" chassis with up to 12 slots. When using multi-slot chassis, the converter may be combined with any other modules from the Enterprise Access family.
In addition, the MICROSENS product portfolio offers active converters for optical or electrical/optical adaptation of data channels to the appropriate wavelengths and required ranges.
Using WDM as transmission technology, network operators can build an infrastructure that may be expanded depending on need. In addition, the capacities in all sub-areas of the network are expandable. This represents an advantage no other technology can provide. Using passive multiplexers is of interest for cable network operators, too. This technology will allow providing additional services such as combining bi-directional data services with uni-directional TV transmission without any problem, while using the existing infrastructure.
