Fiber in Metal Tubes (FIMT) are essential components in modern cable solutions, enhancing application efficiency by enabling features such as long-distance data transmission and fully distributed fiber optic sensing. As a pioneer in the Austrian market with over 25 years of expertise in fiber optics, NBG offers a broad range of design options and customized products that meet and exceed industry requirements.
Optical fibers are the backbone of modern telecommunication networks worldwide. The growing demand for data transmission requires rapid and cost-effective expansion. FIMT in central position or in the stranding layer provides optimal mechanical protection for fibers, ensuring a durable and future-ready network infrastructure.
FIMT has become the global standard for integrating optical fibers into energy cables, enabling long-distance data transmission and fully distributed measurements of temperature, acoustics, and strain, while ensuring complete electromagnetic compatibility (EMC). NBG is the leading supplier of FIMT for energy cables in Europe.
Fiber counts of up to 192 fibers and continuous lengths of up to 50 km without splicing have established NBG as a key supplier for cable manufacturers of repeated and unrepeated submarine cables. Industry-leading attenuation performance and longitudinal water tightness position NBG as a major player in this market.
FIMT diameters ranging from 1.1 mm to 7.0 mm demonstrate NBG’s design flexibility, ensuring the optimal solution for any umbilical project. Additional layers of polymer or stranded steel wires can be configured according to customer requirements.
Our fiber optic products for the energy and telecommunications sectors are manufactured according to customer specifications. The following popular design configurations demonstrate the scope of our production capabilities.
