Demonstration of high-performance cost-effective 100-Gb/s TWDM-PON using 4×25-Gb/s optical duobinary channels with 16-GHz APD and receiver-side post-equalization

Abstract

We experimentally demonstrate 100-Gb/s TWDM-PON with 4×100-GHz-spaced 25-Gb/s optical duobinary channels in the C-band for downstream transmission. Using 16-GHz APD with post-equalization, we achieve a loss budget of 37 dB after 20-km SSMF transmission with 1:512 power split.
