Kernel Adaptive Filtering for Nonlinearity-Tolerant Optical Direct Detection Systems
arXiv:1811.02915
Abstract
Kernel adaptive filtering (KAF) is proposed for nonlinearity-tolerant optical direct detection. For 7x128Gbit/s PAM4 transmission over 33.6km 7-core-fiber, KAF only needs 10 equalizer taps to reach KP4-FEC limit ([email protected]), whereas decision-feedback-equalizer needs 43 equalizer taps to reach HD-FEC limit ([email protected]).
