Paper Abstract

In this paper, we proposed a promising nonlinearity (NL) estimation technique based on error vector correlation (EVC) function, which is robust against ASE noise. The method is demonstrated to estimate NL power accurately in 112 Gb/s polarization-multiplexed quadrature phase-shift keying (PM-QPSK) simulation system, 224 Gb/s PM-16-quadrature amplitude modulation (PM-16-QAM) system and 672 Gb/s wavelength division multiplexed (WDM) PM-16-QAM system. For all of these three systems, the maximum estimation error of NL power is lower than 1 dB for 2400 km transmission link with launch power varying from 0 to 8 dBm per channel when the OSNR range used in simulation of QPSK and 16-QAM system are 12 ~ 30 dB and 18 ~ 36 dB respectively.
