Simple dynamic model of fibre amplifiers and equivalent electrical circuit

Conclusions: In this Letter, a new modular analogue neuro-chip set with an on-chip learning capability is presented for adaptive nonlinear equalisers. Using the analogue neural equaliser, digital telecommunication receivers do not need, and can eliminate, supplementary devices such as analogue-to-digital converters and digital equalisers. Although several chips are used for experiments, one-chip integration is readily possible. The chips operate in real time, even with nonminimum phase channels.
