光纤传输在地震台信号传输中的应用

深圳地震台处于强雷电干扰地区,雷电干扰的破坏给深圳地震台的各类设备带来严重的损害,造成较大的经济损失,后来在信号传输线路上改用了光纤传输,起到了明显的效果。作者将深圳台在应用光纤传输地震信号的实践工作进行简要总结,供一线台站的同行参考。

The Application of Optical Fiber Transmission in the Signal Transmission of Seismic Stations

Earthquake monitoring stations are generally located in the suburbs or in the mountain areas.The locations of many stations are seriously disturbed by lightning,which threats the security of all kinds of earthquake monitoring equipment.Furthermore,all signals are attenuated greatly after a long distance,and the quality of the signals become poor.Shenzhen Seismic Station is also located in an area likely to be attacked by lightning.Once,the disturbance of lightning caused serious damage to the equipment of Shenzhen Seismic Station.The economic loss was heavy.Subsequently,optical fiber transmission has been used for signal transmission and palpable effects have been achieved.This article summarizes the practice of using optical fiber to transmit signals at Shenzhen station and can be of some reference to other counterparts.
