Optical cable ADSS (full name: Augmented Distance Relaying System) is a new type of optical fiber communication transmission technology, which has the advantages of anti-bending, anti-torsion, and anti-tension. It is widely used in the fields of electricity, petroleum, and chemical industry. This article will introduce the working principle, advantages, and application fields of optical cable ADSS in detail.

Optical cable ADSS is a fiber optic communication system that uses distributed fiber Bragg grating (DFB) as a sensing element. When the optical cable is subjected to external forces such as stretching and bending, the sensing element will produce a slight deformation. By measuring the deformation, the status of the optical cable can be monitored in real time. When the optical cable fails, the system will automatically send a signal to notify maintenance personnel to perform maintenance.

Advantages of Optical Cable ADSS

1. Anti-bending, anti-torsion, and anti-tension: The optical cable ADSS uses a distributed fiber Bragg grating, which has high strength and rigidity, can effectively resist various external forces, and ensure the safe operation of the optical cable.

2. High reliability: The optical cable ADSS uses a passive sensor, which does not require energy consumption, so it has very low power consumption. Since the sensor element is located inside the optical cable, it is not affected by the external environment and has high stability and reliability.

3. Real-time monitoring: The optical cable ADSS can monitor the status of the optical cable in real time. Once an abnormal situation is found, the system will immediately issue an alarm, so that timely measures can be taken to avoid accidents.

4. Easy maintenance: The optical cable ADSS adopts a prefabricated structure, which is very convenient for installation and maintenance. Since the sensor element is located inside the optical cable, it does not need to open the optical cable for maintenance, which greatly reduces the maintenance cost.

Application fields of optical cable ADSS

1. Power industry: Optical cable ADSS is mainly used for the protection and monitoring of transmission lines in the power system. Through real-time monitoring of optical cables, transmission line failures can be effectively prevented and the stable operation of the power system can be ensured.

2. Petroleum and chemical industry: Optical cable ADSS is mainly used for the safety monitoring of long-distance oil and gas pipelines in the petroleum and chemical industries. Through real-time monitoring of optical cables, pipeline leakage and breakage can be discovered in time to ensure the safe transportation of oil and gas.

3. Transportation industry: Optical cable ADSS is mainly used for the safety monitoring of infrastructure such as railways, roads, and bridges in the transportation industry. Through real-time monitoring of optical cables, cracks and deformations of roads and bridges can be discovered in time to ensure the safe operation of transportation facilities.

4. Other fields: In addition to the above application fields, optical cable ADSS can also be applied to other occasions where real-time monitoring and protection of optical fiber communication systems are required, such as military communications, aerospace, etc. As a new type of optical fiber communication transmission technology, optical cable ADSS has many advantages and broad application prospects. With the development of science and technology and people's increasing demand for communication security, I believe that optical cable ADSS will be more widely used in the future.
