Analysis and optimization of shot-gun protected cables for ADSS applications

摘要

The purpose of this paper is to present an optimization of protection for the optical dielectric self-supporting cables (ADSS) against the rifle shooting of the hunters. Generally used for transport networks, these loose tubes or micromodules cable designs require a respectable level of protection that varies according to customer and country specifications. We will begin with an introduction on the different levels of protection requested including the different families of cable concerned. Then we will make a short analysis of the shot-gun conditions of tests listed especially in Europe to determine the most relevant criteria which will lead us to a test protocol better adapted to the most severe conditions. We will then choose among the most common cable designs that we will submit to these tests, in order to compare results. After analysis, we will propose a set of new optimized designs including additional elements with more suitable materials, that combined together will achieve a more effective level of protection. Finally, each of these new designs will be submitted to the test protocol, and a summary of results will be presented and commented according the chosen parameters. We will demonstrate that it is possible to improve our products through these new structures, in order, to better target the levels of protection covering the current demand in Europe including the highest.
