The Fiber Optic Sensing Association (FOSA) released details on more than 1,300 installations of distributed fiber optic sensing (DFOS) around the world. The data reflects the largest representative sample ever published.
In an interactive map, FOSA provides a geographic breakdown of global DFOS installations in more than 75 countries. Key insights include:
- China had more deployments than any other nation with roughly 11.3% of all identified installations, followed closely by Germany at 9.4%. The United States came in third with roughly 6.5%, and South Korea was fourth with 4.8% of installations.
- Assets most frequently monitored using DFOS included power cables (22.2%), tunnels (20%), pipelines (13.5%), and perimeters (8.4%).
- The more than 1,300 identified installations span more than 20,000 miles in length (33,300 km).
“According to our data, the United States is well behind China and Germany in terms of total deployments of fiber optic sensing. We are committed to raising awareness of this powerful technology, which can help bring U.S. infrastructure and asset security into the 21st century,” said Mark Uncapher, Director of FOSA. “It is critical that American industry and policy makers understand fiber optic sensing so we can ensure that the United States keeps pace with other global technology leaders.”

Fiber optic sensing enables highly precise remote monitoring of physical assets, including power cables, pipelines, railways, international borders and critical infrastructure. These capabilities are unlocked through the measurement of deviations of light in a fiber optic cable occurring as a result of acoustic, temperature or strain signals.
Industries that already leverage DFOS include transportation, energy, security, oil and gas, and defense. FOSA maintains an extensive list of case studies.
The new data reflects information provided by FOSA member companies’ reference lists. Reference lists are comprised of projects determined by a company to be representative of its total deployments. FOSA members surveyed include AP Sensing, Asymmetric Technologies, Fotech Systems, LIOS Technology, Omnisens, OptaSense and OZ Optics. Oil and gas down-hole applications are not represented in this survey.
