Hainan Railway has worked day and night to ensure the safety of communication submarine cables

At 23:00 on December 7, the network management center showed that the optical cable in the Qiongzhou Strait area was interrupted, potentially affecting a large number of important large customers
, including banks and railways.
Hainan Railway immediately cooperated with the ownership of submarine optical cables, and dispatched technical backbones to meet with China Submarine Cable Company to Qiongzhou Strait
.
After on-site inspection, it was preliminarily judged that the cause of the fault was damage to the submarine cable
caused by the unauthorized anchoring of the vessel.
Technical backbone personnel urgently landed on the construction ship "Fengyang Haigong" and rushed to the fault point of the Qiongzhou Strait to carry out optical cable salvage work
.

At noon on the 8th, the salvage of the Haikou side optical cable at the submarine cable interruption point was smooth, and the construction personnel completed the work of clearing the fault point and setting the pontoon, and began to salvage the Xuwen side optical cable
in the early morning of the next day.
Due to the influence of the strong cold air in the north, the wind on the sea surface gradually strengthened, and the rapid speed became a stormy wave, in order to operate safely, the construction vessel had to temporarily return to the Haikou port area to shelter from the wind
.

At 06:00 on the 10th, the wind at sea weakened, and the Tietong people set off again, and after 48 hours, in the strong bumps brought by the tide, the emergency repair fighters completed the repair of the break point
.

After many days of hard work, the construction personnel successfully completed the salvage and repair of the faulty submarine cable, and all the interrupted business was restored, showing the concept of "customer as the root, service-oriented" of Hainan Tietong, and escorting the information security of Hainan Province
