Fiber optic sensing interrogators for transport infrastructure monitoring.
The Swedish Transport Administration (Trafikverket) is procuring distributed fiber optics sensing interrogators for monitoring and measuring purposes. The procurement covers the supply of interrogators capable of distributed acoustic sensing (DAS) and distributed temperature sensing (DTS) along fiber optic cables. Key requirements include compatibility with existing infrastructure and specific technical specifications for sensing range and resolution. The contract is expected to have a duration of several years with options for extension. Bidders must demonstrate experience in similar installations and provide references.
