Abstract
The transit times of light pulses as functions of
temperature in nylon and acryl-coated fibers and hard-clad silica (HCS)
fibers are analyzed theoretically and compared with the measured
results. The effect of temperature on the transit time can be explained
in terms of generally known models and the physical and thermal
coefficients of the materials. The thermal effect in a core-cladding
interface can have unpredictable consequences, however, as in HCS
fibers. Because of the increased inhomogeneities at the interface of the
core-cladding, the transit time of a light pulse increases, in contrast
to that in a glass fiber, at lower temperatures. Thus the light pulses
have larger angles of propagation than is shown by the numerical
aperture of the fiber, and at the same time the attenuation of the fiber
increases.
