Hello friends,
I would like to know about electrical CPFSK modulator component in Optisystem in which there are two ports one is for binary input another one generates electrical output. i just wanna know that CPFSK is a modulation format like NRZ or RZ If yes then can i generate a signal like PBRS connected with CPFSK and then modulate with CW laser via MZM.
In some papers of Radio over Fiber they used directly as i mentioned but some paper uses like 10 gbps NRZ data is modulated with DPSK or what ever modulation they are using. I am confused because electrical CPFSK or DPSK cannot take electrical input if we generate data with NRZ and then modulate. Please help me out is CPFSK, DPSK etc are modulation formats like NRZ or RZ…….
