Abstract
This paper has demonstrated the simulation study of the high speed dense wavelength division multiplexing (DWDM) transceiver optical communication system based hybrid FSO/OFC channel for local area network applications. The modulation techniques are employed such as coherent binary frequency shift keying (CBFSK), coherent binary phase shift keying (CBPSK), noncoherent binary frequency shift keying (NBFSK), and differential binary phase shift keying (DBPSK). The spectral channel losses and the spectral channel dispersion are demonstrated versus the spectral operating wavelengths and FSO/OFC communication channel based on different modulation technique with the optimum network reach. Output modulated power and maximum Q factor are clarified against various amplification techniques and the spectral operating wavelengths for both FSO and OFC communication channel based on DBPSK modulation technique with the optimum network reach. Optimum output modulated power and optimum signal per noise ratio (signal quality) are studied and simulated in relation to overall network reach based FSO/OFC communication channel with DBPSK modulation technique and EDFA–Raman–EDFA amplification technique.
