Abstract [en]
We propose to add optical amplifier(s) to passive optical interconnect (POI) at top-of-rack in datacentres and validate this approach by introducing impairment constraints into POIs design. It is shown that one amplifier can improve scalability by a factor of 16. Asia Communications and Photonics Conferene (ACP)

Conclusions We introduced a physical layer impairment analysis in the design of a coupler-based ToR architecture and quantified its scalability. We found that without any additional strategy to enhance the scalability, the basic POI architecture may become infeasible. Placing a single EDFA improves the POI scalability by a factor of 16 while maintaining the cost and energy consumption in a similar level.
