Fiber optic components for umbilical cables
Our Fiber in Metal Tubes (FIMTs) are essential components for the production of high-performance umbilical cables, ensuring durability and efficient data transmission in demanding underwater environments.
FIMT for umbilical cables
Our FIMTs are engineered to withstand the rigorous conditions of underwater use, providing both structural integrity and reliable fiber optic communication capabilities. Their construction allows for high fiber density, accommodating numerous fibers in a compact space, which is essential for the multifaceted functionality of umbilical cables. With the capability to be supplied in lengthy, continuous stretches, they reduce the need for frequent splicing, thereby enhancing the overall efficiency and reliability of the umbilical cables. NBG’s focus on quality manufacturing ensures that these FIMTs are not just components, but critical enablers of advanced, durable, and efficient umbilical cable systems, essential for a wide range of maritime and subsea applications.

Frequently asked questions
What are the benefits of using FIMTs in umbilical cables?
FIMTs in umbilical cables offer enhanced protection for fibers, high fiber density for superior data transmission capabilities, and are ideal for sensing applications. These benefits are critical for the reliability, efficiency, and performance of umbilical cables in demanding environments.
How does the high fiber density in FIMTs benefit umbilical cable applications?
High fiber density allows for a greater amount of data to be transmitted through a single cable, maximizing the bandwidth and efficiency of communication lines. This is particularly beneficial for umbilical cables that need to support multiple functions simultaneously, including power delivery, data transmission, and real-time monitoring.
What sensing applications can be supported by FIMTs in umbilical cables?
FIMTs in umbilical cables can support a range of sensing applications, such as Distributed Temperature Sensing (DTS), Distributed Acoustic Sensing (DAS), and Distributed Strain Sensing (DSS). These applications are vital for monitoring the operational health of the umbilical system, environmental conditions, and ensuring the safety and efficiency of operations.
What is the maximum continuous length available for FIMTs in umbilical cables?
We can produce FIMTs in continuous lengths of up to 50km. This reduces the need for splices, simplifies installation, and enhances the integrity and reliability of the cable system.
What is the fiber density of a FIMT?
Our FIMTs for umbilical cables can accommodate up to 192 fibers in a single tube. This high fiber count is advantageous for complex applications requiring substantial data transmission capabilities, such as remote operations and real-time monitoring.
What types of water-blocking solutions are available for FIMTs?
We offer a variety of water-blocking gels and yarns for FIMTs in umbilical cables, tailored to prevent water ingress and protect the fibers. These solutions ensure the durability and reliability of the cable, even in the challenging underwater environment
