The biggest culprit of the "strike" of submarine optical cables

In recent years, the "strike" of submarine optical cables has occurred from time to time. Why is the submarine cable so fragile?

image003_副本.jpg

Submarine cable is a wire covered with insulating material laid on the seabed, usually buried 1-2 meters deep under the seabed, to establish telecommunication transmission across the sea.

Most of the offshore cable accidents in the offshore area are caused by offshore fishing operations such as fishery fishing and anchoring of ships. In particular, the large iron anchors used for sailing nets on fishing vessels are most dangerous. This kind of anchor has two or three tons of weight, and the so-called "fan net" is to take this big iron anchor with a huge canvas "parachute" and cast it into the sea. If the anchor is to hang the cable at the bottom of Shanghai, it may be at sea at any time. Cable tears.

In October 2003, when a fishing boat was pulled at the anchorage, the undersea cable to Chongming Island was accidentally broken. This accident caused the reception of at least 30,000 cable TV subscribers on Chongming Island to be blocked and lasted for nearly 4 days.

In addition, submarine cables are easily displaced or broken during an earthquake. Asia’s Pacific Rim region is one of the most earthquake-prone regions in the world, and the submarine optical cable is the most serious.

Every year, submarine cable breaks occur. There are several submarine cables in the optical cable that the East Sea and Huanghai landed in Shanghai. Submarine cables that have been broken have become even more fragile. The repaired fiber optic cable will float on the sea floor, and it will be more easily damaged by anchors or other things that go down to the seabed. In the late 1980s, there were instances where the polyethylene insulators of deep-sea cable were shaved by sharks causing power failure.
