Abstract :
We propose a remotely pumped EDFA-based 40-Gb/s downstream and 10-Gb/s upstream transmissions long-reach WDM-PON scheme with the downstream transmission implemented by QPSK transceiver and the upstream transmission implemented by FBG optical equalizer-based RSOA IM-DD. Transmissions of 40-Gb/s QPSK downstream using MZ Modulator and 10-Gb/s NRZ-OOK upstream using a 1.2-GHz RSOA equalized by FBG are demonstrated with 40-km fiber transmission.
