What does the three stares of optical cables refer to?

　　The "three-mark" of optical cable refers to the measures taken when there is external construction near the optical cable line, which may endanger the safety of the optical cable line and may cause the failure of the optical cable line. The "three-mark" here specifically refers to "keep an eye on it, keep an eye on it, and keep an eye on it to the end." It is a powerful measure and effective means to prevent and reduce the failure of optical cable lines, and it is also the focus of line failure prevention.

　　More specifically, the "three eyes" work includes the following aspects:

　　Keep an eye on it: Require relevant maintenance personnel to pay close attention to the construction dynamics near the optical cable line, and immediately report and take corresponding monitoring measures if any signs of construction are found.

　　During the construction period near the optical cable line, maintenance personnel need to maintain their posts and monitor the construction site around the clock to ensure that the safety of the optical cable line is not threatened.

　　After the construction is completed, the maintenance personnel still need to conduct follow-up observation of the optical cable line for a period of time to ensure that the construction does not cause any potential damage or hidden dangers to the optical cable line.

　　In addition, the "three-watch" work also needs to pay attention to the following points:

　　Clear responsibilities: Identify the responsible person at the "three marks" site to ensure that the marking work is effectively implemented. The responsible person needs to be familiar with the basic situation of the routing and burial depth of the optical cable line in order to respond quickly in an emergency.

　　Communicate with the construction unit: Establish effective contact information with the construction unit, grasp the construction trend and progress, and jointly protect the safety of the optical cable line. When necessary, a safety agreement can be signed to clarify the responsibilities and obligations of both parties.

　　Strengthen inspection and recording: Regularly inspect the "three-watch" site to ensure that the safety of the optical cable line is in good condition. At the same time, do a good job of relevant records to provide valuable reference information in subsequent analysis and summary.

　　Take necessary protective measures: During the "three-mark" process, if it is found that the construction behavior may cause damage to the optical cable line, necessary protective measures should be taken immediately, such as setting up warning signs, adding markers, etc.

　　To sum up, the "three-mark" work of optical cable is one of the important measures to ensure the safe and stable operation of optical cable lines. By paying close attention to construction dynamics, clarifying responsibilities, communicating with construction units, strengthening inspections and records, and taking necessary protective measures, the occurrence of optical cable line failures can be effectively prevented and reduced.
