A new SNR budget for hollow-core fiber suggests that distributed inter-modal interference, not Kerr nonlinearity, is the main limiter for higher-order QAM. The study outlines how low dispersion and near-vacuum nonlinearity could extend 1024-QAM reach far beyond standard single-mode fiber, while still leaving practical constraints for 2048-QAM and 4096-QAM at 32 GBaud.
