With the continuous improvement of the degree of informatization, the application of optical cables is becoming more and more extensive, and the troubleshooting and maintenance of optical cable lines are more important. It is an important responsibility of the maintenance department to master the fault inspection and repair technology of optical cable lines, eliminate faults in a timely manner, and ensure that the lines are unobstructed. .

1. Pay attention to the following points when troubleshooting:

(1) When the long-distance optical cable line at the junction of the provincial border or the two maintenance units fails, the two adjacent maintenance units should check and repair at the same time.

(2) Optical cable line maintenance units at all levels should accurately grasp the information of their optical cable lines. Proficient in the testing method of the obstacle point of the optical cable line, and can accurately analyze and determine the position of the obstacle point. Always maintain a certain emergency repair force, and be proficient in the operation procedures of line emergency repair and the use of emergency equipment.

(3) Optical cable maintenance personnel should be familiar with optical cable line information, be proficient in line emergency repair procedures, obstacle testing methods and optical cable connection technology, strengthen emergency repair vehicle management, and be ready for emergency repairs at any time.

(4) Special equipment, tools, instruments, machinery and vehicles for emergency repair must be relatively concentrated, and a list should be listed, ready at any time, and generally not allowed to be borrowed or misappropriated.

2. The following points should be paid attention to during the processing:

(1) During the repair of the optical cable line, attention should be paid to the safe operation and use of instruments and equipment. Before the optical fiber fault test, the optical fiber under test is physically disconnected from the optical transceiver at the opposite end.

(2) Once the fault is eliminated and passed the strict test, immediately notify the maintenance department to verify the transmission quality of the optical cable and resume communication as soon as possible.

(3) Seriously do a good job of fault inspection and repair records. After troubleshooting, the line maintenance department should organize relevant personnel to analyze the cause of the failure in a timely manner in accordance with relevant regulations, organize technical data and report it. Summarize experience and lessons and propose improvement measures.

(4) When intervening or replacing the optical cable, the same type of optical cable from the same manufacturer as the faulty optical cable should be used, and the optical cable joints and optical fiber connection loss should be minimized as much as possible. The length of the fiber optic cable involved or replaced in the troubleshooting process should generally not be less than 200m, and the same manufacturer and the same type of fiber optic cable should be used as much as possible. The average splice loss of single-mode fiber should not exceed 0.2dB/piece. After troubleshooting and relocation, the bending radius of the optical cable should not be less than 15 times the cable diameter.

The above are some points to pay attention to when judging and handling optical cable faults. I hope to help you deal with the fault smoothly. If you have any questions, you can consult the online customer service of the website.
