At Bandweaver, reliability has always been central to the design of our Distributed Temperature Sensing (DTS) systems. To validate this, we recently completed a comprehensive update of reliability data for our FireLaser and T-Laser DTS solutions.
The results are compelling.
- Telcordia SR232 Standard: Independent testing by Anbotek (2018) confirmed an MTBF (Mean Time Between Failures) of over 255,000 hours, equivalent to 29 years.
- Field Data: Drawing from more than 28 million operational hours across installed systems (2017–2025), real-world data shows a current MTBF of approximately 560,000 hours, an impressive 64 years.
These figures clearly demonstrate that FireLaser is not just designed for reliability but continues to outperform expectations in the field. With no moving parts, passive fiber optic cables, and robust system architecture, maintenance requirements remain exceptionally low.
For operators working in safety-critical environments such as tunnels, metros, and petrochemical facilities, this level of reliability provides reassurance that FireLaser is built to protect assets over the long term while minimising operational costs.
