Mixture of optical quadrature-phase shift keying and continuous-phase frequency shift keying advanced methods for monitoring optical performance in future photonic networks. ISAS 2023 - 7th International Symposium on Innovative Approaches in Smart Technologies, Proceedings. 10.1109/ISAS60782.2023.103916819798350383065https://hdl.handle.net/20.500.12939/4614This research shows that hybrid fibre systems that transmit data using both CPFSK and OQPSK (optical quadrature-phase-shift-keying) modulation techniques function well. It examines how the maximum Q factor and the minimum bit error rate vary with modulation frequency and fibre length using the proposed hybrid modulation transmission techniques. Fibre length variations at a constant modulation frequency of 300 GHz also simulate variations in optical power and received electrical power. It uses hybrid modulation techniques for CPFSK/OQPSK with 35 bits per symbol and a modulation frequency of 301 GHz to achieve varying maximum Q Factor, minimum BER, maximum signal power, and minimum noise power throughout a 35 km fibre length.eninfo:eu-repo/semantics/closedAccessContinuous-phase frequency shift keying (CPFSK)Frequency modulation (FM)Optical fiberOptical quadrature-phase shift keying (OQPSK)Conference Object2-s2.0-85184824127N/A
