DOI: 10.1364/ol.450756
Abstract: In this Letter, we show numerically and experimentally that multipath interference can be reduced significantly by distributed Raman amplification (DRA) in quasi-single-mode transmission using few-mode fibers, owing to the extra differential mode attenuation induced between… read more here.
