ABSTRACT:
This invention relates to optical fiber cleaving tools where the optical fiber is held in a first clamping device, a portion of said fiber is passed through and elongated open which is coaxial with the long axis of said fiber, and through a second coaxial clamping device, which places said fiber in tension. A sharp pointed means is positioned between the exit of said elongated opening and said second clamping device, adjusted to score the circumferential periphery of said fiber. The tension on said fiber causes it to cleave in a mirror-surface plane which is substantially perpendicular to the longitudinal axis of said fiber. Herein, the cleaving tool of this invention produces mirror-surface ends, at least about 1.degree. of the desired 90.degree., and even essentially 90.degree.. In this invention the second clamping device is distinguished in that one clamping face is an arc of a defined circular circumference. Also this cleaving tool is unique in its capability of cleaving either buffered optical fiber or bare optical fiber, with the results as set out above.
