We propose a novel physical model-based QoT estimation with achieved OSNR estimation error ≤ 1.5 dB in primary paths and OSNR prediction error ≤ 1.76 dB in unestablished lightpaths for both super-C bands and super-C+L bands for the first time.

We propose a novel technique to measure Kerr nonlinearity in a hollow-core fiber based on nonlinear phase shift estimation by high-order QAM transmission. The measured n2,Kerr of the NANF-5 medium is <2.20×10-23 m2/W.
