This article presents the optical fiber sensor system for weight surveillance, by relying on the bending principle, which uses the testing equipment. The loss of the work is due to the bending of the fiber, bringing the light to a pressed weight, as well as analyzing the impact of the parameter value, such as the wavelength of light. The width of the light pulse set in the video, the result of the experimental results showed that the light wavelength 1650 nm is the wavelength of a long-running loss due to the most bending. The width of the pulse light used to experiment from 3 NS to 1000, NS will have a similar loss of work, and the relationship between the loss of the light and the the weight of the fiber. This can be applied as a optical fibre sensor system for weight monitoring.
