Abstract

Performance optimization of ultra-long Raman laser links is studied theoretically and experimentally. We demonstrate that it is possible to reduce the signal power excursion by adjusting FBG reflectivity without compromising pump efficiency. Furthermore, we experimentally demonstrate an OSNR improvement of 4.3 dB in our system after 4000 km transmission by switching from conventional erbium-doped fibre amplifiers to quasi-lossless transmission.

Uncontrolled Keywords: performance optimization, ultra-long Raman laser links, signal power excursion, FBG reflectivity, pump efficiency, OSNR improvement, erbium-doped fibre amplifiers, quasi-lossless transmission
