Abstract: The length of the optical fiber section under tension expands by a certain amount that is proportional to the level of tension applied to it. Monitoring the variations in the phase of the arriving signal allows to discover a fiber that is subject to a certain level of mechanical tension. With the method and apparatus according to the present invention it is possible to protect optical communication channels against failures in an optical transmission fiber that are caused by any kind of mechanical disturbances.
Abstract translation: 张力下的光纤部分的长度膨胀一定量，与施加到其上的张力水平成正比。 监测到达信号的相位变化允许发现受到一定程度的机械张力的光纤。 利用根据本发明的方法和装置，可以保护光通信信道免受由任何种类的机械干扰引起的光传输光纤中的故障。
