微细光缆静水高压环境下的传输衰减特性试验研究

Experimental study on transmission attenuation of Fiber Optical Micro Cable under high hydraulic pressure

最近我国也研制成功了微细光缆,该光缆直径小于1mm,极限拉伸强度约400N。如果它在高压环境下的传输衰减特性能满足要求,则它在很多水下工程结构如各类大潜深潜水器以及海底观测基站上会有很广泛的应用前景。文章的主要目的就是介绍该种国产微细光缆在静水高压环境下的传输损耗试验情况。文中对微细光缆的静水高压传输损耗试验进行了介绍和描述,并对试验结果进行了初步分析,获得了一些有用的结论。

A kind of Fiber Optical Micro Cable （FOMC） was developed recently in China. The diameter of FOMC is only about lmm but with an ultimate tensile strength of 400N.This FOMC can be widely used in many underwater engineering structures such as submersibles and subsea stations if its transmission attenuation under high hydraulic pressure is also good. The purpose of this paper is to introduce this issue. The high hydraulic pressure test of FOMC＇s transmission attenuation is introduced. The test procedure and the test results are presented and some useful conclusions are drawn.
