Study of the optical phenomena in a 10 km long optically powered data link dedicated to a submarine cabled observatory

Abstract

International audienceWe describe a 10 km long optically powered data link dedicated to a submarine cabled observatory. A single optical fiber is deployed to both transmit the exchanged data and the energy to supply the remote instrument. We focus on the optical phenomena which occur in the optical fiber due to the presence of the high optical power, and its superimposition with the optical data streams. We study the advantages, the constraints and the limits of such a system, and we determine the best configuration to collect the maximum electrical power after the O/E conversion, and to transmit the data with the best quality

Quantitative evaluation of fiber fuse initiation with exposure to arc discharge provided by a fusion splicer

“…Heat-induced strong absorption of silica glass optical fiber at more than 1050 °C 1 plays a potential risk in many fiber optics applications including optical communication and “power over fiber”, as a form of fiber fuse phenomenon 2 3 4 5 . In the 28 years since its discovery, many techniques have been used to initiate a fiber fuse, namely local heating of a fiber segment.…”
