We have experimentally demonstrated the gain-clamped wideband optical amplifier using a DCF-based Raman amplifier and an semiconductor optical amplifier for 90-nm wide bandwidth amplification with good gain flatness (of 3 dB) as well as dispersion compensation of 10Gb/s DWDM signals over 100-km SMF link. The power penalty of 0.4 dB for the gain-clamped amplifier with lasing light at 1508 nm has been achieved as compared with the non-gain-clamped amplifier case. Such gain-clamped light within the SOA suppresses the cross-gain modulation (XGM) effect of the SOA and therefore the XGM-induced power penalty dramatically reduced. This amplifier may play an important role in MAN for high speed and broadband delivery between city interconnection. |
