Control of upstream optical repeaters for SuperPON access networks

摘要

This paper reports on the control systems for upstream optical repeaters in a long range high-split ratio SuperPON access network. Optical amplification means of fast switching semiconductor optical amplifiers is used. Two methods to control the drive current of the optical amplifiers are described: a feed forward self-triggered scheme and a topology using a priori known talker identity information. Trade-offs between both systems will be discussed. The first alternative was used in a lab demonstrator set-up, while the second will be used in a small field trial.
