Abstract

Coherent optical transmissions (i. e. systems in which the phase is used to code information) have been extensively studied as a way to increase the performances of communication systems. In parallel to this, developments in the use of soliton propagation have provided an attractive solution to the requirements of high bit-rate, long-haul transmissions The potential use of high capacity soliton-based coherent links depends on the robustness of the soliton phase with respect to the amplified spontaneous emission (ASE) noise introduced by the in-line erbium doped fiber amplifiers (EDFA) We assess here experimentally the phase jitter, and compare it to the theoretical predictions
