We supply specialized Fiber in Metal Tubes (FIMTs) as core components for manufacturers of high and medium voltage cables. Our FIMTs are distinguished by their high fiber density, accommodating up to 192 fibers in a single tube—optimizing space and maximizing data transmission capacity.
Available in continuous lengths of up to 50 kilometers, our FIMTs minimize the need for splicing and enhance cable reliability. Every product reflects NBG’s commitment to precision manufacturing and strict quality control, ensuring seamless integration into advanced cable systems.
Our FIMT and fiber optic products for HV / MV 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.
