At present more than 55 million kilometers of the standard type single mode fibre (SMF) have been installed. Showing zero dispersion at a wavelength of about 1310 nm, SMF offers great potential when the bitrate × distance product is considered, if it were not for the attenuation of the fibre. Therefore, design of very high speed digital transmission systems in the 1300 nm region is very attractive. Recently significant progress has been achieved in the development of Quantum Well Laser Amplifiers (QWLAs) with the use of suitably strained Quantum Well materials [1,2]. Although a few promising results have been published using these amplifiers [3, 4], especially a 10 Gbit/s transmission over 200 km, representing a record NRZ transmission capacity using Semiconductor Laser Amplifiers (SLAs), the study on the performance of cascaded QWLAs in high bitrate long haul transmission systems is far from completed yet.
