We study the fundamental energy consumption of fiber-optic communications links. We show that the quantum limit for the energy efficiency of a multi-span system deploying generalized on-off keying with photon-counting inline regeneration exceeds by orders of magnitude that of state-of-the-art systems employing inline optical amplification.

Abstract
We study the fundamental energy consumption of fiber-optic communications links. We show that the quantum limit for the energy efficiency of a multi-span system deploying generalized on-off keying with photon-counting inline regeneration exceeds by orders of magnitude that of state-of-the-art systems employing inline optical amplification.File in questo prodotto:
