Accelerated aging and life tests of optical fibers

2000

The reliability of the network optical fibers is a critical issue for telecommunications.New investigations methods have been developed within a cooperative program supported by France Telecom. They include low coherence interferometry and optical near field microscopy in association with classical analysis tools such as Scanning Electron Microscopy and Shear Force Microscopy. One aim of the study is the localization and the characterization of the defects from which failure originates. The aging effect has been investigated in silica fibers immersed in desionized water at 65 oc and 85 "C for different times: from 3 to 12 months

Interférométrie et réflectométrie haute résolution en lumière incohérente : modélisation d'interférogrammes

1999

International audience; Nous présentons des résultats infrarouge de réflectométrie à basse cohérence dans des fibres optiques, des guides d'onde et des coupleurs afin de détecter les échos dûs aux défauts de propagation réflective et pour mesurer leurs propriétés optiques: pertes ou atténuation, dispersion. Cette technique est basée sur l'interférométrie et donne la plus haute résolution spatiale avec la plus faible puissance optique réfléchie. Nous balayons le bras de référence de notre interféromètre de Michelson autour de la position de la " frange en lumière blanche " et nous obtenons des interférogrammes dont les enveloppes et les franges contiennent l'information sur le spectre de la …
