Design and Implementation of 10Gbps All-optical 2R Regenerator

Abstract- An All-optical 2R regenerator (Reamplification and Reshaping) is a crucial element in optical communication systems in order to increase transmission performance. In this paper, an all-optical 2R regenerator is implemented by self-phase modulation (SPM) based spectral broadening and offset filtering. Design calculations of the required parameters for the proposed 2R regenerator are carried out. Simulation results in terms of power transfer and bit error rate (BER) measurements are shown to prove the effectiveness of the proposed system. After the optical signal has been degraded by 500 km- long transmission span, the 2R regenerator in this work can reshape the degraded signal by achieving only 0.3dB power penalty at BER of 1
