About LandSub Global
A distributed fiber optic sensing infrastructure provider, founded by a team of fiber-optic sensing engineers — delivering equipment and solutions for critical asset safety.
Fully in-house engineered fiber sensing
LandSub Global designs and manufactures distributed fiber optic sensing (DFOS) equipment — DAS (Distributed Acoustic Sensing), DTS (Distributed Temperature Sensing) and DTSS-BOTDR (Distributed Strain & Temperature Sensing) — plus specialized products and services for oil & gas, power, transportation and mining.
Our fully in-house engineered optical path, structure and demodulation algorithms — combined with proprietary AI pattern recognition and sensing-communication fusion — deliver industry-leading specifications and reliable early-warning across long-distance linear assets.
Four in-house technology moats
In-house optical design
Full-stack self-developed optical path, structure and process.
Proprietary demodulation
0.03 rad/√Hz sensitivity via gauge + optical design.
AI pattern recognition
In-house image + acoustic AI for event classification.
Sensing-communication fusion
One fiber core carries both communication and sensing.
