Abstract

The tester flexes fiber bundles without inducing tensile stress in the fibers. The test involves clamping bundles 1 of flexible fiber optics in free suspension between a nonpressurized nip of a pair of cylindrical mandrels 2 and 3, mounted between end plates 4 and 5. The assembly is oscillated as a wit about shaft 6 by a gear train driven by crank 7. The latter is pivotally connected by a pin 12 i one of two radially displaced holes 13 and 14 to link 8. The latter is pivotally mounted in one of holes 10 and 11 of drive wheel 16. This is driven by motor 17.

Fiber Optics Flex Tester

The tester flexes fiber bundles without inducing tensile stress in the fibers. The test involves clamping bundles 1 of flexible fiber optics in free suspension between a nonpressurized nip of a pair of cylindrical mandrels 2 and 3, mounted between end plates 4 and 5. The assembly is oscillated as a wit about shaft 6 by a gear train driven by crank 7. The latter is pivotally connected by a pin 12 i one of two radially displaced holes 13 and 14 to link 8.

The latter is pivotally mounted in one of holes 10 and 11 of drive wheel 16. This is driven by motor 17.

After the fiber bundles 1 are loaded between mandrels 2 and 3, motor 17 is started. Rotary rotation at drive gear 16 is translated through link 8, crank 7, and the gear train into oscillatory motion of mandrels 2 and 3 together with the end plates 4 and 5 to which they are mounted. During such oscillation the hanging fiber bundles 1 are alternately wrapped in conformity about mandrels 2 and 3.

Optionally, the free ends of the optic fibers can be weighted to assure intimate wrap around the mandrels. The specific angle of oscillation can be selected by changing the mounting of link 8 in holes 10 and 11 and 13 and 14 in drive gear 16 and crank 7 respectively. Oscillations of 90 degrees and 180 degrees in alternate directions are obtained by changing the stroke by appropriate selection of the mounting of link 8.
