Abstract

We propose a remotely pumped Er-doped fiber amplifier (EDFA)-based 40-Gb/s downstream and 10-Gb/s upstream transmission long-reach wavelength division multiplexing passive optical network (WDMPON) scheme with downstream and upstream transmission implemented by quadrature phase-shift keying (QPSK) transceiver and reflective semiconductor optical amplifier (RSOA)-based intensity modulation direct detection (IM-DD). Transmissions of the 40-Gb/s QPSK downstream, using a Mach-Zehnder modulator, and the 10-Gb/s non-return-to-zero on-off keying (NRZ-OOK) upstream, using a 1.2-GHz RSOA equalized by fiber Bragg grating (FBG), are demonstrated with 40-km fiber transmission.
