Optical Fiber Behavior Under Inert Atmosphere

Résumé

Optical fibers are made from fused silica glass surrounded by a protective coating and the optical strength is almost entirely determined by the strength of the glass. In telecommunications applications the single biggest cause of system failure is failure of the cable and it is not easy to estimate the theoretical maximum strength of fibers which depend on applied stresses and used environment. On the other hand, glass optical fibers were almost always coated with a polymer immediately after drawing to protect them from subsequent handling damage and from chemical environment. For the study of fiber strength, it was useful to be able to remove this coating in order to directly observe the fatigue properties of the glass in immediate contact with the environment. The mechanical strength of coated and stripped silica optical fibers has been investigated through aging in the air and in an inert atmosphere. Dynamic tests for different faceplate velocities were implemented using a two-point bending testing device in order to determine the median strength for coated and stripped fibers from Weibull statistics. The analysis of the Weibull curves demonstrates the influence of the used atmosphere on the fiber strength as well as the role of the polymeric coatings. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
