Optical fiber connector

An optical fiber connector comprising:

• a first holder for holding a first connection end of a first optical fiber and a second holder for holding a second connection end of a second optical fiber, the first holder and the second holder including:
• a first holder portion and a second holder portion disposed therein, respectively, the first holder portion and the second holder portion including:
• a first holding groove and a second holding groove disposed therein, respectively, the first holding groove holding the top half of the first connection end and allowing the bottom half thereof to be exposed, the second holding groove holding the bottom half of the second connection end and allowing the top half thereof to be exposed, the top half and the bottom half being defined with respect to a central axis of at least one of the first and the second optical fibers, the first holding groove and the second holding groove including:
• a pair of first inclined planes and a pair of second inclined planes, respectively, provided therein, the first inclined planes aligning the top half of the first connection end and the second inclined planes aligning the bottom half of the second connection end;
• wherein a first fiber end surface of the first optical fibers recedes from a first holder end surface of the first holder portion and a second fiber end surface of the second optical fiber recedes from a second holder end surface of the second holder portion, the first holding groove and the second holding groove oppose each other so as to sandwich at least one of the first connection end and the second connection end therebetween, and the receded portion of the first holding groove aligns the second optical fiber such that the first fiber end surface and the second fiber end surface are butt-spliced by coupling the first holder and the second holder together.
