Optical Time Division Multiplexing by Locking Lasers (OTDMLL)
Optical Time Division Multiplexing by Locking Lasers (OTDMLL) is an analog multiplexing technique, which is suitable for multiplexing different types of analog signals, digitally modulated analog signals or data signals. By integrating this technology into in-building wireless platforms one can increase the efficiency by a factor of 4. Furthermore, by employing a technology agnostic approach that supports both digital and analog signals, the project design is significantly simplified.
OTDMLL samples RF inputs at 10 Gb/s and higher sampling rates, utilizing several laser transmitters, each sampling a different RF signal. This is accomplished by dividing the optical signal into very short time segments and multiplexing optical data streams to a single optical path, and then reassembling them at the receiving end.
The addition of OTDMLL will enable another level of multiplexing (on top of the WDM multiplexing). This approach allows the delivery of 4 times as many channels on a single fiber. Furthermore, the OTDMLL technology is agnostic to the original signal’s frequency and technology, enabling the multiplexing of any desired mix.
