摘　　要：A simple and cost-effective remodulation scheme using a two-section reflective semiconductor optical amplifier （RSOA） is proposed for a colorless optical network unit （ONU）. Under proper injection currents, the front section functions as a modulator to upload the upstream signal while the rear section serves as a data eraser for efficient suppression of the downstream data. The dependences of the upstream transmission performance on the lengths and driven currents of the RSOA, the injection optical power and extinction ratio of the downstream are investigated. By optimizing these parameters, the downstream data can be more completely suppressed and the upstream transmission performance can be greatly improved.A simple and cost-effective remodulation scheme using a two-section reflective semiconductor optical amplifier （RSOA） is proposed for a colorless optical network unit （ONU）.
