Application of FWM-Based OFC for DWDM Optical Communication System with Embedded FBG Sensor Network

Abstract Four-wave mixing optical frequency comb fibre-based setups (FWM-OFCs) have the potential to improve combined dense wavelength division multiplexed passive network (DWDM-PON) and fibre Bragg grating (FBG) temperature sensors providing easier application, broader technological opportunities for development, energy efficiency by substituting a power-demanding laser array. In this research, OFCs are generated purpose of application DWDM-PON FBG sensors. The paper also investigates compatibility scenarios with in such systems. mathematical simulation model has been developed performance FWM-OFC based 8-channel 50 GHz spaced non-return-to-zero on-off keying (NRZ-OOK) modulated transmission system, operating at km single-mode (SMF) bit rate least 10 Gbps embedded 7 sensors, studied. As it is shown, FWM results OFC source that fluctuations individual tones less than 3 dB power, an extinction ratio about 33 operation range 192.9–193.25 THz, acting as unified light all data channels. Embedded causes negligible 0.3 power penalty.
