Long-Haul Optical Transmission of 16-QAM Signal with In-Line Phase-Sensitive Amplifiers

We demonstrate transmission of a 10 GBd 16-QAM signal with low-noise in-line phasesensitive amplifiers in a recirculating loop experiment. A fourfold reach improvement is obtained at optimal launch powers using phase-sensitive amplification compared to phase-insensitive amplification.
