Optical fiber: It is the abbreviation of optical fiber. It is made of pure quartz and is drawn with a special process into a glass tube that is thinner than a hair and has several media in the middle. It is a kind of fiber that uses the principle of total reflection of light in a fiber made of glass or plastic. Achieved light transmission tool. Its texture is brittle and easy to break, so it needs an external layer of protection.

Handling after a fault occurs. Different types of line faults have different processing priorities.

The interruption of optical cable lines due to external factors or the optical fiber itself, which affects communication services, is called optical cable line failure. Optical cable line failures cause business interruption for a long time and affect a wide range of business areas. They are a key link in safe broadcasting work. In order for the optical cable communication system to work normally, in addition to careful design, careful construction, and normal maintenance, once an optical cable failure occurs, it must be dealt with in a timely manner to ensure that the line is smooth and the failure time is shortened as much as possible. This is an important part of improving communication quality.

Optical fiber: shorthand for optical fiber. It is drawn from pure quartz with a special process into a glass tube thinner than a hair with several media in the middle. It is a kind of fiber made of glass or plastic based on the principle of total reflection of light. Achieved light transmission tool. Its brittle texture necessitates an extra layer of protection.

1. Distance judgment When the computer room determines that the fault is an optical cable line fault, the line maintenance department should test the faulty optical cable line in the computer room as soon as possible, and use the OTDR test to determine the location of the line fault point.

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

1.1 The optical cable is completely broken If 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.

Fiber optic cables are indispensable for modern power supply and communication. Once there is a problem with the fiber optic cable, it will block the communication business and bring great changes to our life. To solve this problem, we should understand the fiber optic cable failure.

Optical fiber connectors are suitable for high-speed optical fiber links. High-loss optical fiber connectors may cause network failures. Do troubleshooting.

Fiber break, broken fiber is divided into two types: partial interruption and the entire optical cable interruption

The first category is the optical attenuation caused by the too small bending radius of the optical cable.

When bending the optical cable, the minimum bending radius cannot be exceeded.

1. Burial depth. Since the direct buried optical cable is directly buried under the ground, there must be a certain distance from the ground. With the help of the tension of the ground, the optical cable will not be damaged. At the same time, the optical cable should also be protected from freezing.
