What this paper is about?
Four-wave mixing optical frequency comb fiber-based setups (FWM-OFCs) have the potential to improve the combined dense wavelength division multiplexed passive optical network (DWDM-PON) and fiber Bragg grating (FBG) temperature sensors network providing easier application, broader technological opportunities for network development, and energy efficiency by substituting a power-demanding laser array. Application where OFCs are generated for the DWDM-PON and FBG optical sensors combined network and investigates its compatibility with such a system. The mathematical simulation model has been developed and the performance of FWM-OFC based 8-channel 50 GHz spaced non-return-to-zero on-off keying (NRZ-OOK) modulated DWDM-PON transmission system, operating at 50 km single-mode fiber (SMF) with a bit rate of at least 10 Gbps embedded with 7 FBG optical temperature sensors has been studied. As it is shown, FWM application results in OFC source that has fluctuations of the individual comb tones of less than 3 dB in power, and with an extinction ratio of about 33 dB for operation range of 192.9 – 193.25 THz, acting as a unified light source for all the data transmission channels. Embedded FBG optical sensors network causes negligible 0.3 dB power penalty.
The article will be published at the end of 2022 or the beginning of 2023.
