Overview
Multiplexer/ Demultiplexer
The optical passive Multiplexers, Demultiplexers and Optical Add-Drop Multiplexer (OADM) devices are essential building
blocks of the LambdaDriver Optical Transport System (OTS).
A Multiplexer/Demultiplexer pair aggregates several different wavelengths onto a single pair of fibers – the WDM trunk –
and relay them to a remote location for distribution.
The Multiplexer/Demultiplexer and OADM devices are protocol transparent and completely passive. Since they do not
require electrical supply for their operation, these modules can be used also in non-powered intermediate locations in a
WDM network.
The Multiplexer/Demultiplexer pairs are mostly used in Point-to-Point applications and also in conjunction with OADMs in
Linear add/drop topologies where some of the services are dropped at different locations along the line.
OADMs re-direct specified channels (wavelengths) received over the trunk connection to discrete add/drop ports and
transparently pass the remaining channels.
Special OADM type of modules - the Banded OADM – are used to add/drop a predefined bundle of channels at a location
where these channels will be distributed individually.
Important add-on to the Multiplexer/Demultiplexer building blocks are the Band Splitters.
The Band splitters are used to provision easy and seamless expansion of operating DWDM networks without interrupting
their operation.
As an example, a network can be designed to start with using 16 DWDM C band RED channels and later on expand by
adding 16 DWDM C band BLUE channels over the same WDM trunk through a RED/BLUE Band Splitter.
Band Splitters are available also for the C/L bands integration.
Multiplexer/Demultiplexer devices are available with 8, 16, 40, and 80 DWDM channels and for 8 and 16 CWDM channels.
OADM devices are available with 1,2,3 and 4 channels in DWDM and CWDM technologies.
8-DWDM-channels OADM modules with 8 sequential wavelengths exhibit very low pass through attenuation.
Due to their passive structure, these devices introduce optical power loss for every optical signal that passes through the
device. Each port of a passive device can have different insertion loss and therefore during network designs these losses
should be considered (see technical specifications table overleaf ).
