Abstract : Optical fibre sensors are designed majorly for detecting and gauging various parameters. These sensors provide different benefits over traditional sensors, making them more valuable in different applications. They are capable to detect very small changes in actual parameters to measure in case of biosensing. With this sensitivity, they can detect subtle changes in pressure, strain, temperature, vibration, refractive analytes, and other factors with utmost accuracy. They enable remote sensing. As light sensors can carry data, it is possible to place sensing elements at unreachable or distant sites and still convey the data back to core monitoring system without degrading signals. To increase bitrate, this study was focused on transmission of “Optical Time-Division Multiplexing (OTDM)” at 80Gbit/s to optimize the change in phase between opposing OTDM channels. With limited capacity of fibre, there is a need to increase spectral efficiency and use amplitude, phase, and polarization for transmission of signals. Over the years, various approaches and configurations have been proposed to improve sensitivity of sensors based on optical fiber. However, it is believed that selecting the configuration of optical fiber sensors must be chosen as per certain application. As these sensors keep on improving and evolving, they play a vital role in control applications and monitoring around several industries.

Keywords : Optical Time-Division Multiplexing, OTDM, Optical Fibre Sensors, Bitrate, High-Speed Data.
