High-capacity phase-sensitively amplified transmission in a field-deployed fiber cable

High-capacity phase-sensitively amplified transmission in a field-deployed fiber cable

Abstract Phase-sensitive amplifiers (PSAs) outperform conventional phase-insensitive amplifiers by enhancing signal-to-noise ratio (SNR) through distinct gains for deterministic signal and stochastic noise depending on their phase features. Yet despite this potential, the practical implementation of...
