How to form Simulation model of WDM PON using downstream DQPSK & OOK upstream
I have to make a WDM system in which 4 wdm channels are used and i have to use DQPSK modulation format to make my transmitter.And also how to design DQPSK receiver so that one half of the signal is send to the DQPSK receiver and the rest of the downstream optical signal is re-modulated by an intensity modulation technique of 10-Gbps RZ-OOK. The generated upstream signal is transmitted back to the OLT using SSMF through a complete path. How to make this system?
