MUX/DeMUX Module

General

MICROSENS is expanding its product portfolio of optical Metro solutions by introducing new
passive multiplexers for multiplying transmission capacities of fiber optical connections.

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. These components will make realizing CWDM and DWDM applications
easy.

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.

For bi-directional transmission, both start and end points will then require the appropriate
multiplexers and demultiplexers. Since we are dealing with true passive multiplexing, the
individual optical signals must already be available in their respective wavelengths. The
multiplexers are then selected according to the different wavelengths (window, number of
channels, and wavelength difference).

The design of these components emphasizes ease of installation and start-up of operations, as
well as consistent modularity for optimal adaptability to given communication requirements.

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. These converters are also based on the modular system of the Enterprise Access family,
allowing band-widths of up to 2.5 Gbit/s per channel. Depending on combination and
wavelengths, ranges of up to 80 km can be realized.

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 uni­directional TV transmission without any problem, while using the existing infrastructure.
