FIBER IN METAL TUBES
Stranded Double Layer FIMT
- Ultra-high tensile performance
- Armored optical fiber cable with up to four layers
- Distributed Acoustic Sensing (DAS) in harsh environments
Armored Optical Fiber Cable
Our Stranded Double Layer FIMT (RDT) provides the highest possible optical fiber protection, suitable for harsh environments. The armored optical fiber cable performs in extreme temperatures ranging between -60°C to +300°C (-76°F to 572°F), and it withstands mechanical stress and environmental influences to offer maximum optical lifetime.
We produce the RDT using a wide array of steel grades. The configuration could have as many as four inner tube layers, meaning clients only pay for the performance they need. As many as 192 optical fibers fit into the design; it’s the perfect solution for fiber optic sensing and data transmission.
