Signal-to-noise considerations in fiber links with periodic or distributed optical amplification

Yariv, Amnon

Abstract

The detected signal-to-noise power ratio is evaluated for fiber links with periodic amplification. It is shown that the highest ratio is achieved in the limit of a distributed amplifier (g = α), but that, alternatively, periodic amplification at intervals of α^-1 entails a penalty of less than 2 dB compared with the (ideal) distributed case.
