The use of a receiver-integrated semiconductor optical amplifier (SOA) for gain transient suppression in wavelength division multiplexed passive optical networks is proposed and experimentally studied. the effectiveness of SOA transient suppression is investigated as a function of the optical input power into the SOA for a 10 Gbit/schannel disturbed by power transients. Near-perfect correction of a 2.3 db transient power penalty for transmission over a 25 km standard singlemode fibre link is demonstrated by using an SOA with a holding beam.
