What type of fiber is used for distributed fiber optic vibration sensing?

The type of fiber used for distributed fiber optic vibration sensing is single-mode G652, which is a very common fiber, and almost all of our communication fiber optic cables are of this type and are not expensive.

Usually in the field environment, the fiber optic cable used is armored fiber optic cable, and often there are multiple cores. Our distributed fiber optic vibration sensing system only requires the use of a single fiber core, which allows a single multi-core fiber optic cable to be multiplexed.

To do the test in the laboratory, we can use the bare fiber for the laboratory, a whole tray can be 20KM is very suitable.
