Welcome to the Fiber Optic Sensing Association

The Fiber Optic Sensing Association (FOSA) is dedicated to accelerating the use of distributed and quasi-distributed optical fiber sensing technologies.

Fiber optic sensing works by measuring changes in the “backscattering” of light occurring in an optical fiber when the fiber encounters vibration, strain or temperature change. It can be deployed to continuously monitor vehicle movement, human traffic, digging activity, seismic activity, the health of structures and assets, temperatures, liquid and gas leaks, and many other conditions and activities. Fiber optic sensing is used around the world to monitor smart infrastructure, including tunnels, railways, bridges, borders, power stations and pipelines. It is also used in down hole oil and gas applications, to help characterize reservoirs and assist in well-optimization during production and completion.
