Abstract:
1. An optical fiber connector for connecting a first optical fiber to a second optical fiber comprising: a first graded-index fiber detachably attached to a light exit end of the first optical fiber, for enlarging a beam diameter of a light incident from the first optical fiber and producing the collimated light; and a second graded-index fiber detachably attached to a light entry end of the second optical fiber, for reducing the beam diameter of the collimated light incident from the first graded-index fiber and leading the converging light into the second optical fiber, wherein, the first graded-index fiber and the second graded-index fiber satisfy following expressions: wherein, L 1 represents a length of the first graded-index fiber, L 2 represents a length of the second graded-index fiber, and one pitch represents a single sinusoidal period of an optical path of the light transmitted through the first graded-index fiber.
