LambdaDriver® Band Splitter Module
EM800-MP2, EM800/1600-RBBS
The optical passive splitter and interleaver modules are important building blocks of the LambdaDriver® Optical Transport System and serve at optical communication nodes to divide /split and transport the optical bandwidth as portions of optical sub-bands. The applications include:
a. In service Power monitoring - A portion (usually 5%) of the incoming optical signal is taken to a "monitor" port for connecting to measurement equipment while the rest of the signal is transported transparently to
the output port.
b. Separating the Optical spectrum to different bands - Band Splitter devices transport a specific band of DWDM channels to an output port.
As an example the "Red"/"Blue" Band Splitter separates the Incoming optical signal between two Output
ports, each forwarding only the channels that belong to the specific band (Red or Blue).
c. Combining/Splitting DWDM 100Ghz spaced channels over 50Ghz spacing transport - Interleaver. In order to increase the number of DWDM wavelength forwarded over existing infrastructure, 100GHz spaced channels shifted by 50Ghz are combined by the interleaver thus doubling the number of channels transported over
the same media.
The functionality of the above mentioned modules permits performing seamless and uninterrupted network scalability and addition of new services.
Dual and quad Red/Blue and L-band/C-band Band Splitter modules are available as part of the Lambda Driver Optical Transport System.
The Optical Power Monitoring device is a special splitter that filters 5% of the incoming optical signal to a separate interface on the module while the remaining 95% continues its path without being additionally affected due to the high (min 40db) isolation between the monitoring port and the main path.
Measuring and analysis equipment can be attached to the monitoring port for troubleshooting or advanced alert purposes. 50% power splitters are also available.
