A coherent-based OLT receiver with a power-controlled optical local oscillator for upstream OFDM/TDMA-PON

摘要

We propose a novel upstream OFDM/TDMA-PON using a coherent-based OLT receiver having a power-controlled local oscillator, achieving a power normalization range of 20dB and power budget of 29dB in 60-km transmission for 20-Gb/s 16QAM-OFDM system.
