Abstract	Two adaptive Orthogonal Frequency Division Multiplexing (OFDM) modulation formats are experimentally characterized for high data-rate transmission (>10Gb/s) in Reflective Semiconductor Optical Amplifier (RSOA) based access network. The performance of these multi-level modulation techniques is severely affected by non-negligible chirp parameter of RSOA. Here, it is shown that the OFDM system based on water-filling algorithm is not able to guarantee full transmission capacity. In contrast, by using power pre-emphasis technique, transmission capacity is improved up to 17.1 Gb/s at the bit error rate (BER) within Forward Error Correction (FEC) limit over 25 Km fiber span by using commercially available RSOA of limited bandwidth (<1 GHz).
