“…9, the power consumption reduction depends on the input optical power passing into the MC-EDFA. In single-core WDM optical networks, the number of wavelength multiplexed optical carriers passing through the single-core optical link depends on the network topology model, traffic demand distribution model, optical path model, and route and spectrum allocation (RSA) algorithm for optical path design [26], [27]. The number of wavelength multiplexed optical carriers may differ depending on single-core optical links.…”

We realize a multicore erbium-doped fiber amplifier (MC-EDFA) with 2 dB optical gain improvement (average) by recycling the residual 0.98 µm pump light from the MC-EDF output. Eight-channel per core wavelength division multiplexed (WDM) Nyquist PM-16QAM optical signal amplification is demonstrated over a 40-minute period. Furthermore, we demonstrate the proposed MC-EDFA's stability by using it to amplify a Nyquist PM-16QAM signal and evaluating the resulting Q-factor variation. We found that our scheme contributes to reducing the total power consumption of MC-EDFAs in spatial division multiplexing (SDM)/WDM networks by up to 33.5%.
