Abstract
A device having two sets of raised portions inside a metal case is provided for bending an optic fiber. According to some embodiments, the two sets of raised portions are on two plates that are biased apart by a spring means. According to some embodiments, the metal case prevents viewing of an optic fiber in the metal case. According to some embodiments, an adjustable stopping element is provided to limit movement of the two plates toward each other.
Claims19
A device comprising:
- a first plate having at least two raised portions;
- a second plate having at least two raised portions;
- a spring means biased to pull the plates apart;
- a metal case enclosing the first plate and the second plate and defining a first opening on a first end of the metal case and a second opening on a second end of the metal case wherein the first opening and the second opening are sized to accept an optic fiber.

An optic fiber bending device comprising:
- a first set of at least two raised portions;
- a second set of at least two raised portions;
- a metal case enclosing the first set of at least two raised portions and the second set of at least two raised portions and defining a first opening on a first end of the metal case and a second opening on a second end of the metal case wherein the first opening and the second opening are sized to accept an optic fiber and wherein the metal case is designed to shield portions of the optic fiber from view;
- and
- a light sensor capable of sensing light that escapes the optic fiber placed in the metal case.
2 more elements
An apparatus comprising:
- a first movable plate having a first protrusion;
- a second fixed plate having a second protrusion such that when the first movable plate is moved toward the second movable plate while an optic fiber is in contact with the first protrusion and the second protrusion, the optic fiber is bent;
- and
- an adjustable stopping element that extends from the second fixed plate toward the first movable plate and limits movement of the first movable plate toward the second fixed plate.
