The combined effect of temperature and humidity on the fatigue parameters and reliability of optical fiber

Proceedings of SPIE - The International Society for Optical Engineering (Impact Factor: 0.2). 09/2004; 5465. DOI: 10.1117/12.582546


The lifetime of an optical fiber depends on its environment. Previous work extensively measured and characterized the separate effects of humidity and temperature on the fatigue parameters using three different kinetics models, but the combined effect has not been determined in detail. In this work, the details of how the fatigue parameters vary with temperature in a humid environment were investigated. It was found that the kinetics model parameters were different from values obtained elsewhere in liquid water. This may be the result of differences in the apparent activation energy for fatigue in liquid and vapor environments.

    ABSTRACT: A new type of cable is introduced for protecting optical fiber from mechanical bending or abrupt temperature changes. It shows superior ability to protect fiber from severe bending and lowers the thermal sensitivity compared with conventional optical fiber cable. It can be used as a protection sleeve or cable in special regions. The proposed device consists of a helical composite spring, a thermal insulator (i.e., polyurethane foam) and a heat-shrinkable tube which coats the outside of the spring. These components can be acquired for a moderate price and manufactured by simple processes.

    ABSTRACT: As aerospace instruments become increasingly more precise and elaborate, the mechanical limits of glass components can become key design constraints. The probabilistic fracture behavior of glass is complex, and dependent on many variables. Typically, to avoid such complexity, overly simplistic strength estimates are employed that fail to take advantage of well understood glass properties. Such a simple approach requires the use of conservative strength values that encompass the weakest possible cases. This results in optic designs that, while robust, are unnecessarily massive and display excess wavefront error and instability, threatening mission viability. This paper presents a complete approach to glass strength analysis, as compiled from existing literature, incorporating both the principles of fracture mechanics and details of the specific design in question. The mathematical formulae needed to accurately predict failure rates of individual glass components using laboratory data are presented. The result is a method of analysis that accurately represents our understanding of fracture and uses known information about the specific mechanical design. By replacing conservative strength values with detailed, application specific survival forecasts, engineers gain greater design freedom. Optic mass and performance can be more effectively optimized, improving instrument performance.

    ABSTRACT: Interferometric fiber-optic gyroscopes exhibit time-dependent rate error patterns during operation due to environmental stress on the fiber coil. Short-term errors, equilibrating on the order of minutes to several hours, are attributed to nonreciprocity due to thermal gradients. Long-term rate errors, equilibrating on the order of days to weeks, have not been thoroughly addressed. In this study, we show that diffusion of moisture into or out of a sense coil can cause long-term rate errors. To calculate this effect, we measured the effect of moisture on the mechanical properties of the optical fiber coating. Using these data, we modeled diffusion in a sense coil with finite-element analysis. The rate error is calculated with an integral that is similar to that used by Shupe and others. A variation in water concentration in the coil due to diffusion causes changes in the properties of the fiber coating. This in turn produces nonreciprocal stresses on the waveguide and leads to a rate error.
