TL;DR
This paper investigates how optimizing launch power in hybrid-amplified optical links improves signal quality, showing modest SNR gains over uniform power schemes and highlighting the benefits of hybrid amplification.
Contribution
It introduces a method for per-channel launch power optimization in hybrid-amplified links and compares its performance to uniform power schemes, demonstrating SNR improvements.
Findings
Average SNR gain of 0.13 dB with hybrid amplification
Compared to 0.56 dB gain with lumped amplifiers only
Hybrid optimization offers better performance than uniform power
Abstract
Per-channel launch power optimisation in a hybrid-amplified link with optimised pump powers and wavelengths is described. Compared to using the optimum spectrally uniform launch power, an average SNR gain of 0.13 dB is obtained against 0.56 dB for the same system operating with lumped amplifiers only.
