The emergence of the Internet not only makes the spread of information faster, but also shortens the distance in the world. Even if you are in Xinghua, Jiangsu, China, you can quickly know the weather in Rosario, Argentina, which is nearly 20,000 kilometers away ( The two places are 19,996 kilometers apart and were once considered the two most distant cities on earth). When it comes to the Internet, one thing must be mentioned - submarine optical cables.
Submarine optical cable, also known as submarine communication cable, is a facility laid on the seabed to establish telecommunications transmission within and between countries. Since seawater is a natural means of shielding external optical and magnetic wave interference, after the submarine cable is successfully laid, it can achieve long-term operation while maintaining a high signal-to-noise ratio (the design life of submarine optical cables is generally 25 years).
In fact, submarine optical cable is a complete system, including shore equipment and underwater equipment, and the optical cable itself is actually an important and fragile part of it. Because of this, the maintenance and repair of submarine optical cables has become very important. However, precisely because submarine optical cables are laid on the seabed, it is not easy to obtain operating data of submarine optical cables. And just recently, a device that has just been put into use has transformed into a "see-through eye" in the sea and successfully helped the staff complete the task. Undertaken the maintenance work of submarine optical cables.
According to Xinhua News Agency, on April 20, in the waters of Yushan Island, Zhoushan City, Zhejiang Province, a submarine cable maintenance vessel successfully obtained a magnetic vector submarine cable fault detection device that had just been put into use. Submarine cable operational data.
It is understood that one of the characteristics of the magnetic vector submarine cable fault detection device compared with traditional detection devices is the use of vector magnetometers. The vector magnetometer can detect the relative orientation between it and the cable in real time, help the submarine cable maintenance ship correct the measurement route, and accurately find abnormal points of the submarine cable. According to relevant personnel, the put into use of the magnetic vector submarine cable fault detection device can save nearly half of the time in finding submarine cable fault points and greatly improve the efficiency of submarine cable maintenance.
