Abstract :
We propose a remotely pumped EDFA and tunable transmitter-based 40-Gb/s/λ downstream and 10-Gb/s/λ upstream transmissions long-reach WDM-PON scheme and an optical beat noise-based novel automatic wavelength control method for tunable transmitter. Transmissions of 40-Gb/s DQPSK downstream using MZ Modulator and 10-Gb/s OOK upstream using optical beat noise-based self wavelength managed tunable transmitter are demonstrated with 40-km fiber.
