Optical connecting method and optical connection structure
First Claim
1. An optical connecting method for optically connecting by abutting ends of a first optical fiber and a second optical fiber against each other, the first and the second optical fibers being secured to a first plug and a second plug, comprising the steps of:
- threading the first optical fiber through the first plug and threading the second optical fiber through the second plug to secure each optical fiber to each plug with a securing part;
bending a part of at least one of the first optical fiber and the second optical fiber that is present ahead of the securing part;
aligning the first optical fiber and the second optical fibers and fixing a relative position between the first and second plugs; and
releasing a flexure of at least one of the first optical fiber and the second optical fibers for abutting the first optical fiber and the second optical fibers.
