Development of optical signal regeneration technique using ultrascale field programming gate array

B. Das, M.F.L. Abdullah


The optical signal regeneration is a demanding research area for long-haul optical communication systems. The existing optical signal regeneration techniques are not facilitating for low BER in real-time. In this paper, a new optical signal regeneration technique is developed that provides low BER in real-time for 10Gb/s optical  degraded signal for Differential Phase Shift Keying (DPSK) signal at different transmission distances between 50 km to 250 km. The developed optical signal regeneration technique has achieved a very low Bit Error Rate  (BER) of 10-13 at low received the power of -17 dBm averagely for DPSK signal at different transmission distances experimentally via UltraScale FPGA.

Keywords: Bit Error Rate (BER); Differential Phase Shift Keying (DPSK) signal; Optical Signal Regeneration,  Field Programming Gate Array.
