High sensitivity

Lightweight and flexible, easy to install and buried

Electrical insulation and chemical stability. Optical fiber itself is a highly insulating and chemically stable substance, which is suitable for harsh environments such as high-voltage barrier and flammable and explosive in power systems and chemical systems

Outstanding security. Optical fiber sensor is a passive sensitive element of electricity, so when used in measurement, there are no potential safety hazards such as leakage and electric shock

Immunity to electromagnetic interference. In general, the frequency of light waves is higher than the frequency of electromagnetic radiation, so the propagation of light in optical fibers is not affected by electromagnetic noise;

Distributed measurability. An optical fiber can complete long-distance continuous measurement and control, and can accurately measure the strain, damage, vibration and temperature information on any point, and thus form a monitoring area with a large range to improve the detection level of the environment

Long service life. The main material of the optical fiber is quartz glass, which is coated with a polymer material cladding, which makes it have greater durability than metal sensors

Large transmission capacity. With optical fiber as the bus, the transmission of large-capacity optical fiber is used instead of the cumbersome multi-core underwater cable to collect and store the information of each sensing point, and the distributed optical fiber sensor monitoring is completed through multiplexing skills
