Development and Real Time Implementation of Optical Signal Regeneration for Different Modulation Schemes Using ULTRASCALE FPGA

Optical Signal Regeneration (OSR) is a demanding research area for long haul optical communication systems. Electronic signal regeneration is limited due to its real-time infeasibility in terms of data rate and accumulated losses. The existing optical signal regeneration techniques have not been able to facilitate low power consumption, demonstration of real-time low cost commercial based design systems and application for the optical systems. This create a huge need of developing the new high-speed energy efficient OSR techniques for long haul optical communication. In this talk, I will be discussing the development of new OSR technique that offers low power consumption, low BER and commercial based design for real-time high-speed optical degraded signal. The new OSR is demonstrated for different modulation formats of high-speed degraded signal  transmitted at different transmission distances between 50 km to 250 km over single mode fiber using UFPGA. Aim of the talk of is to give overview about low power real-time implementation of optical system design using UFPGA.
