1. The processing after the fault occurs, different types of line faults, the focus of processing is different.(1) The same route has a total resistance fault that can be communicated by an optical cable. The personnel on duty in the computer room should use other good fiber cores to block the services on the fiber according to the emergency plan at the first time, and then repair the faulty fiber as soon as possible.(2) For a total resistance fault where there is no optical fiber to connect, follow the emergency plan to implement rush-pass or direct repair of the obstacle point.(3) The optical cable has non-total resistance, and there are remaining optical fibers available. Use spare fiber cores or other optical cables on the same route to pass through services on faulty fiber cores. If there are many faulty fiber cores, not enough free fiber cores, and no other optical cables with the same route, the secondary circuit can be sacrificed to pass through the important circuit, and then the faulty fiber core can be repaired without interrupting the circuit.(4) There is non-total resistance in the optical cable, and there is no remaining optical fiber or optical cable with the same route. If the blocked fiber is an important circuit, use other non-important circuit fibers to pass through the blocked fiber, and use the method of continuous cutover to repair the faulty fiber core urgently.(5) The transmission quality is unstable, and the system is up and down. If there is a spare fiber core or other fiber optic cable with the same route, the service on this fiber can be transferred to other fibers. Find out the reason for the decline in transmission quality and deal with it in a targeted manner.2. Fault locationIf it is determined that the optical cable line is faulty, it should quickly determine which relay section the fault occurs in and the specific situation of the fault, and ask the network management room in detail. According to the judgment result, immediately notify the relevant line maintenance unit to judge the fault point.3. Preparation for emergency repairAfter the line maintenance unit receives the failure notice, it should quickly load the emergency repair tools, instruments and equipment and set off, and at the same time notify the relevant maintenance lineman to find the cause and failure point in the nearby area. The preparation time for emergency repair of optical cable lines shall be implemented in accordance with regulations.4. Establish a communication systemAfter the repair personnel arrive at the fault point, they should immediately establish a communication system with the transmission room.5. Organization and command of emergency repairsThe emergency repair of optical cable line failure is led by the maintenance department. During the emergency repair period, it pays close attention to the on-site emergency repair situation and cooperates well. The emergency repair site is directed by the leader of the optical cable line maintenance unit.While testing the fault point, the emergency repair site should designate a special person (usually an optical cable operator) to organize the excavation personnel to stand by, and arrange the logistics service work.6. Emergency repair of optical cable linesWhen the point of failure is found, emergency optical cable or other emergency measures should be used, firstly, the main optical fiber channel should be cleared, and the communication can be quickly restored. Observe and analyze the situation at the scene, make records, take photos, and report to the public security organs.7. Business recoveryAfter the on-site optical cable repair is completed, the computer room should be notified in time for testing, and communication should be restored as soon as possible after verification is available.8. On-site treatment after emergency repair. After the emergency repair work is over, check the tools and equipment, sort out the test data, fill in the relevant registration, handle the scene, and stay with a certain number of personnel to protect the scene of the rescue.9. Line data update. After the repair work is over, sort out the test data, fill in the relevant forms, update the line information in time, summarize the repair situation, and report to the superior department in charge.Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables,fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!

1.1 The optical cable is completely brokenIf there are reservations on both sides of the site, take centralized reservations and add a joint to deal with them;There are joints near the fault point and there are enough reservations on site, use the method of pulling reservations and using the original joints;There is neither reservation nor joint near the fault point, so it should be solved by cable extension.1.2 Partial bundle tube interruption in fiber optic cable or partial fiber optic interruption in single bundle tubeThe repair is based on the premise that it does not affect other optical fibers in use. It is recommended to use the skylight connection method to repair the faulty optical fiber.2 Analysis of the Causes of Optical Cable Line FailuresThe causes of cable line failure can be roughly divided into four categories: external force factors, natural disasters, defects of the cable itself and human factors.2.1 Line faults caused by external factors(1) Excavation by external force: To deal with the fault of digging by excavator construction, the pipeline fiber optic cable is opened by manpower well near the fault point to check whether the fiber optic cable is damaged in the manpower well, and the two-way test interrupts the fiber optic cable.(2) Vehicle hang-up: When dealing with vehicle hang-up faults, first conduct a bidirectional test on the fiber optic cable at the fault point to confirm the number of places where the cable is blocked, and then deal with it in a targeted manner.(3) Gunshot: This type of fault generally does not interrupt all optical fibers, but damages some parts of the optical cable or optical fibers, but it is difficult to find such faults.2.2 Line faults caused by natural disastersRat bites and bird pecks, fires, floods, high winds, icicles, lightning strikes, electric shocks2.3 Line faults caused by the fiber itself(1) Natural fiber breakage: Since the optical fiber is drawn from glass and plastic fibers, it is relatively fragile, and static fatigue will occur over time, and the gradual aging of the optical fiber will lead to natural fiber breakage. Or the splice box is flooded, resulting in increased fiber loss or even fiber breakage.(2) Effect of ambient temperature: If the temperature is too low, the water in the splice box will freeze, the cable sheath will shrink longitudinally, and the pressure on the optical fiber will cause micro-bending, which will increase the attenuation or interrupt the optical fiber. If the temperature is too high, it is easy to damage the cable sheath and other protective materials and affect the characteristics of the optical fiber.2.4 Line faults caused by human factors(1) Work failure: Human failure caused by technicians in maintenance, installation and other activities. For example, when the optical fiber is connected, the optical fiber is scratched, the bending radius of the optical fiber is too small; the running optical cable is cut off by mistake when the optical fiber is spliced; Broken fiber.(2) Stealing: criminals steal and cut the optical cable, causing the optical cable to be blocked.(3) Destruction: Man-made sabotage, causing the cable to be blocked.Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables, fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!

Optical fiber connectors are suitable for high-speed optical fiber links. High-loss optical fiber connectors may cause network failures. Do troubleshooting.1. What are the faults of fiber optic connectors?The failure of the fiber optic connector may be related to the ferrule, such as cracks, notches, slight bends, cut off, micro cracks, etc. inside the ferrule. In addition to these, it is also related to the optical fiber, such as too much/not enough epoxy resin Or there are unreasonable assembly processes such as air bubbles, as well as reasons such as peeling and improper curling.2. Three major causes of fiber optic connector failureReason 1: The end face is dirty;Point 1: Light spreads poorly or not at all;Point 2: The light is reflected back to the connection point, back to the transmission point, causing the device to malfunctionReason: When there are contaminants on the fiber end face, light may not pass through the fiber end face, resulting in poor fiber loss performance.Treatment method: You can check and clean the end faces repeatedly to ensure that the end faces are clean before pairing. Reason 2: Exceeding the bending radiusPoint 1: Exceeding the bending radius, resulting in high loss;Point 2: Loss that seriously affects the entire linkReason: Excessive bending of optical cables will cause fiber loss, which we call macrobend loss, which usually occurs during installation;Solution: Make reasonable bends according to the supplier's cable bending tolerance specification. If the cable bends in your installation environment exceed the minimum bending radius, it is recommended that you use bend-insensitive fibers. Usually, the minimum bend radius of bend-insensitive fibers is 10mm.Reason 3: DislocationPoint 1: High LossPoint 2: Loss that seriously affects the entire linkReason: Excessive insertion loss is usually caused by fiber misalignment and different fiber materials, there are extrinsic and intrinsic factors:What To Do: Make Sure You Buy Quality Components From Reliable Component ManufacturersFiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables,fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!
