What are the types of distributed optical fibers

There are several types of distributed optical fibers, including distributed fiber temperature measurement, distributed fiber vibration, and distributed fiber acoustic monitoring. How to choose a suitable manufacturer should depend on specific application requirements and manufacturer strength. Below is an introduction to the types of distributed optical fibers:

1. Distributed fiber optic temperature measurement system

The distributed fiber optic temperature measurement system can achieve real-time and online monitoring of cable temperature changes, and can set warning information for multiple monitoring points to prevent dangerous accidents from occurring. Based on the temperature of the cable, the load variation of the cable can be determined, and the load of the cable can be optimized to effectively improve its capacity and efficiency. The distributed fiber optic cable temperature monitoring technology has improved the shortcomings of traditional technology with intelligent control technology, improved the operational level of cables in China, and reduced the incidence of cable accidents.

2. Distributed fiber optic vibration monitoring system

Long measurement distance:

The distributed fiber optic vibration monitoring system measures a long distance, with a detection distance of up to 40km;

Accurate positioning:

Accurately locate intrusion and leakage points, and display them directly on the software interface;

Continuous distributed measurement:

Can achieve simultaneous monitoring of multiple points and events without affecting each other;

High sensitivity and rapid response:

The fiber optic vibration monitoring system responds quickly to the tested area and has an extremely low false alarm rate;

System stability:

It can be used in dangerous and harsh environments. All fiber optic products of Fuzhou Huaguang Tianrui undergo strict quality inspection and simulated environmental testing before leaving the factory to confirm their adaptability to various harsh environments;

3. Distributed acoustic monitoring

Compared to traditional distributed fiber optic monitoring technology based on temperature monitoring, DAS technology for acoustic signals can integrate multiple monitoring physical quantities to identify and provide real-time feedback on various fault modes such as pipeline rupture and leakage. The perimeter security monitoring of important areas such as airports, nuclear power plants, and industrial plants is crucial for the safety of personnel and the stable and normal operation of equipment. Real time monitoring of perimeter security and real-time localization of intrusion sources are of great significance.
