Methods of emergency repair measures for fault of communication optical cable

1, the processing after the fault occurs, different types of line faults, the focus of processing is different.

(1) The same route has a cable can be replaced by a total resistance fault. According to the emergency plan, the personnel on duty in the equipment room should use another good fiber core to block the services on The Optical Fiber and then repair the faulty optical fiber as soon as possible.

(2) The total resistance failure without optical fiber can be directly repaired according to the emergency plan, and the principle of "first important circuit, then secondary circuit" should be followed when the replacement or repair is carried out.

2. Locate the fault

If the fault is determined, determine the trunk segment in which the fault occurs and the specific fault information, and consult the network management equipment room. According to the judgment result, immediately notify the relevant line maintenance unit to detect the fault point.

3. Prepare for emergency repair

After receiving the fault notification, the line maintenance unit should quickly load the emergency repair tools, instruments and equipment and start, and notify the relevant maintenance lineman to find the cause and fault point in the nearby lot. The preparation time for emergency repair of Optical Cable lines shall be implemented in accordance with regulations.

4. Establish a communication system

After the emergency repair personnel arrive at the fault point, they should immediately establish a communication system with the transmission room.

5. Organization and command of emergency repair

The repair of the fault of the optical cable line shall be conducted by the maintenance department as the business leader, pay close attention to the repair situation at the scene during the repair, cooperate well, and the repair site shall be directed by the leader of the maintenance unit of the optical cable line.

At the same time of testing the fault point, the emergency repair site should designate a special person (generally for the cable operator) to organize the excavation personnel on standby, and arrange logistics services.

6. Repair of optical cable lines

When the fault is located, use emergency optical cables or other emergency measures to connect the main fiber channel first and quickly restore communication. Observe and analyze the situation at the scene, make records, take photos, and report to the public security organs.

7. Services are restored

After the onsite cable repair is complete, notify the equipment room to test it. After verifying that the cable is available, restore the communication as soon as possible.

8. On-site treatment after emergency repair.

After the completion of the emergency repair work, check the tools and equipment, sort out the test data, fill in the relevant registration, process the site, and leave a certain number of personnel to protect the site.

9, line information update.

After the repair work, sort out the test data, fill in the relevant forms, update the line information in time, summarize the emergency repair situation, and report to the superior competent department.
