Double stranded FIMT | NBG Fiber Optics



Reinforced Double Layer


Stranded wires around a Fiber in Metal Tube (FIMT) ensures flexibility and high mechanical performances, while the FIMT protects the integrated optical fibers against mechanical stress, hydrogen and other environmental influence in order to provide maximum optical lifetime for their application. All fiber in metal tube products offered by NBG are produced according highest quality standards in the industry. Dimensionally changes can be optionally as well as the optical components are able to change upon customer requests. With a wide variation range for fiber in metal tube products combined with the highest manufacturing accuracy, our products exceeding the needs and offers great performance in the field.
