Paper Abstract

We present a theoretical model to study the static pressure distribution among the layers of an optical fiber cable spool based on the force analysis of the cable system. Using the distributed fiber Bragg grating (FBG) sensing technique, the static pressures within the fiber cable layers of the spool were measured according to the Bragg wavelength shifts of the FBGs embedded in the cable. The effects of the cable spool shrinkage owing to the pressure from outer fiber cable layers on the cable tension and the radial pressure were analyzed in detail. As a result, the relationship between the static pressure upon the fiber and the resulted Bragg wavelength shift of the FBG was deduced. The static pressure distribution of the fiber optical cable spool is obtained both in theory and experiment. Theoretical simulations coincide with experimental results. This technology provides us a real-time method to monitor the inner pressure among the fiber cable layers during the optical cable winding process.
