Investigations of Backscattering Effects in Optical Fibers and Their Influences on the Link Monitoring

IEEE Photonics Journal, 2017
In this paper, first, we employed the coupled-mode theory to investigate the backscattering power characteristics of Rayleigh backscattering (RB) and stimulated Brillouin scattering (SBS) both synchronously and precisely. We discovered how the RB and SBS

Dead Zone Fault Detection Optimization Method for Few-Mode Fiber Links Based on Unexcited Coupled Higher-Order Modes

Photonics
The traditional single-mode fiber (SMF) optical time domain reflectometer (OTDR) may not be able to accurately detect and locate fault events in the dead zone of few-mode fiber (FMF) links.

Influence of Rayleigh Backscattering on the Performance of NOLM-Based Phase-Preserving Amplitude Limiters

, 2010
Design and fiber optimization in NOLM-type regenerators allow for a substantial decrease in excess noise originating from Rayleigh backscattering. Cascaded operation of up to 20 phase-preserving limiters in a DPSK transmission system is experimentally ...
