Dear All
Hope you all will be fine.
I need to know how to implement the demultiplexing of an optical time division multiplexed (OTDM) signal at receiver/PIN detector by optical clock using optisystem 7 or 16 version???I am attaching a paper where the OTDM signal is demultiplexed by optical clock using VPI Photonics software.Please look at this and comment.
I will be obliged
Regards

    Dear Muhammad,
    You need to make sure that the pulses from different signals fit within single bit period by delaying each stream with partial bit period. Then, the demultiplexing is done in an opposite way by adding a compliment to the delay to have one full bit period for each stream.

    Dear Sir Ahmad
    Thanks for reply

    I understood but one thing need further clarification. what is the role of Clock Pulses?How much will be the data rates of each clock pulse?

    If PRBS is set at 10Gbps with Probability checked, then what will be selection of clock at DEMUX side?

    Please note that the clock for the demodulator for each path is running at the same rate of that path. In the example of OptiSystem all paths have the same rate and their clock is the same at 10G.
