Yes i am planning to use different modulation formats on transmitter side and would make a WDM system.From this i want to compare different modulation formats and see their results.
one half of the signal is send to the DQPSK receiver means that i am using power splitter at the receiver side “one half of the signal is send to the DQPSK receiver if i use DQPSK modulation format to make DQPSK transmitter while the second half of power splitter is re-modulated by OOK(on off keying) and send to the OLT.Last step is that i want to calculate power budget of this scheme.
