The influence of temperature loading on the optical fiber passive components

摘要

The paper discuss about aging of the optical couplers in their burdened high temperature. The article focuses on applied research and experimental development of resources for safety operation of optical networks in environment with higher temperature. It addresses issues of accelerated aging of optical fiber components in their burdened with high temperature. This article is devoted the impact of temperature loading on the SM optical FBT coupler with 8 branches. Optical passive component were exposed to temperature 95 °C for 433 hours. Measurements are focused on the parameters of geometry of optical beam. The detect changes are useful to understand the phenomenon of accelerated ageing elements of optical networks.
