Equivalent noise figure of -6 dB is achieved under 300-mW pump power. Using the experiment results, numerical simulation of ultra-long span systems shows that for a 40 × 11.6-Gb/s transmission system, the RP-EDFA scheme can support transmission of 1760 km with a fiber span of 160 km. These results demonstrate the potential of the PR-EDFA scheme in ultra-long span transmission.展开更多

Both simulation and experiment show that there is an optimal RPPA location and optimal pump power according to the highest performance. The amplified spontaneous Raman scattering (ASRS) self-oscillation caused by Rayleigh backscattering (RBS) and the lump reflector in transmission line are the final performance limitation.展开更多
