Abstract
In this paper, we investigate the optimal design of bidirectional pumped FRA with the impact of co-pumping RIN transfer using the quality factor (Q-factor) analysis for multispan long-haul transmission systems. The benefits from low ASE and MPI noise accumulation, impairments due to nonlinearity enhancement caused by signal amplification and the RIN transfer penalty are taken into account. The optimal operation of bidirectional Raman pumped long-haul multispan fiber system (24×100 km) at 10 Gb/s is calculated according to the copumping percentage, total Raman gain and pump RIN intensity. Both RZ and NRZ modulation format are examined. Our analysis provides a useful tool for the optimization process of bidirectional Raman pumping multispan long-haul transmission system including the requirement of pump RIN.
