2.1-Tb/s.km OFDM Long-Reach PON Transmission using a Cost-Effective Electro-Absorption Modulator

Abstract

We experimentally demonstrate a superior performance of 2.1-Tb/s.km OFDM-signal transmission over 100-km long-reach PONs, which is achieved by using an EAM and direct-detection, and adopting the 128-QAM format and adaptive subcarrier power weighting.
