Abstract

A novel upstream data remodulation scheme with downstream ASK-DPSK modulation format is proposed for WDMPONs in this letter. And this kind of scheme is also experimentally demonstrated on one particular wavelength channel. Both the 2.5-Gb/s downstream optical DPSK signal and the 2.5-Gb/s downstream optical ASK signal are demodulated respectively at the receiving side, while part of the downstream carrier is directly remodulated by an optical intensity modulator for upstream transmission of 2.5-Gb/s data. System performance under different amplitude ratios of downstream optical ASK signal is investigated. It is shown that effective reception and robust performance can be achieved after having been transmitted for 25-km.
