Low Complexity Frequency-Domain Nonlinear Equalization for 40-Gb/s/wavelength Long-Reach PON

Not Accessible

Your library or personal account may give you access

Abstract

We propose to use a frequency-domain nonlinear equalization (FD-NE) for long-reach PONs. Compared with time-domain NE, similar performance with 63% complexity reduction is achieved utilizing FD-NE in a 40.08-Gbit/s OFDM-IM-DD transmission system over 60-km SSMF.
