Distributed Fiber Optic Sensing (DFOS) allows for fully distributed temperature sensing over multiple kilometers without the need of electricity at the measurement position. It is a key technology for monitoring critical infrastructure such as LNG pipelines and tanks, oil and gas pipelines, chemical plants, kilns and other harsh environments.
NBGs cables support Raman, Brillouin, Ralyeigh or FBG based interrogation technologies with Raman being the most common technique for cryogenic and high temp environments. The full metallic protection of the fibers ensure long lasting sensors by protecting the fibers from environmental influence and strain during operation.
Our Cryogenic / High Temp FO cables are manufactured to customer specifications.
Below are just a few examples to demonstrate our production capabilities.
FIMTs are specialized tubes made from metal that encapsulate optical fibers. These tubes protect the fibers from external physical and environmental conditions, ensuring secure and reliable data transmission, especially in high voltage and medium voltage cable applications.
FIMTs enhance efficiency by providing a robust protective environment for optical fibers, which are used for monitoring and communication purposes alongside the electrical transmission. This dual functionality allows for real-time monitoring and control, leading to optimized operational performance and reduced downtime.

FIMTs are typically made from stainless steel or superalloys, offering high resistance to corrosion and physical stresses. Specific materials include common stainless steel variants and superalloys such as Alloy 625, Alloy 825, etc.
FIMTs are integrated into the cable structure either as part of the core or layered within the cable, depending on the cable design. This integration provides added protection for the optical fibers and contributes to the overall strength and durability of the cable.
Yes, FIMTs are ideal for sensing applications such as Distributed Temperature Sensing (DTS), Distributed Acoustic Sensing (DAS), and Distributed Strain Sensing (DSS). These applications are crucial for monitoring the integrity and performance of high voltage/medium voltage cables.
