DWDM ITU Grid
Channel Plans |
Aurora Networks provides a wide variety of products for installation
in both 3RU chassis and optical nodes that support DWDM network architectures,
including narrowcast transmitters and transponders, passive mux and demux modules
and our unique line of modules that integrate narrowcast demultiplexing
functions with broadcast / narrowcast combiners and power level monitoring
capability.
All of Aurora’s DWDM products support an extended range of channels
on the standard DWDM ITU Grid (ITU-T G.694.1, with 100 GHz channel spacing), from
ITU Channel 20 (1561.42 nm) to Channel 59 (1530.33 nm), to provide both capacity
for up to 40 channels and flexibility for network designs.
For multi-channel products, Aurora Networks has defined a convenient
set of logical channel ''groupings'' used for identification and product packaging.
Most of these types of products have model numbers that include a channel group
identifier (using the letters ''J'' through ''U'') based on a sequential partitioning
of the set of ITU channels into 10 groups of four channels each. A graphical depiction
of this schema, together with parametric channel data, is provided in the data sheet
that can be viewed online (in pdf format, 619k bytes)
here.
In the case of passive mux and demux modules, models are also available
which further aggregate these groups into sets of 8 or 16 channels in a single package.
Features
• 40 different channels on the standard DWDM ITU Grid
(ITU-T G.694.1, 100 GHz spacing)
• Convenient logical channel groupings ease network design
• Multi-channel (mux and demux) products available in 4-, 8- and 16-channel
configurations
• Products designed to enable cascading of DWDM signals from module to
module
