The next generation of optical communication networks should provide a significant role for large range high-splitting ratio high-speed passive optical networks (SuperPONs). Optical amplification of both upstream and downstream traffic is necessary to sustain these configurations with several amplifiers in series throughout the network. The Photonic Local Access Network (PLANET), an EU-ACTS project, was developed to operate a 2 - 5 Gbit/s in the downstream direction (from the head-end to the user optical network unit) and at 311 Mbit/s in the upstream. A laboratory-based system demonstrated the feasibility of the SuperPON concept over a span of 100 km to support a potential 2,048 optical network units. The downstream utilized erbium-doped fiber amplifiers whereas in the upstream the use of burst-mode semiconductor optical amplifiers minimized noise funneling effects. Simulation results are presented in this paper for the upstream SOA cascade. Data are provided for the evolution of both the signal power and the amplified spontaneous emission power throughout the amplifier cascade.
