Patent ID: 7128478

Claim:
An optical fiber reinforcing device comprising: a heating and reinforcing device shaped so that a first distance from an end face to a mid point thereof is set to be equal to a second distance from a fusion splicing position of an optical fiber fusion splicing device, which includes an optical fiber holding member and first and second guide portions for holding first and second optical fibers to be formed into a fusion spliced optical fiber with a fusion spliced point, to an end face of the holding member; a positioning means provided on the heating and reinforcing device for aligning a mid point of a heat shrinkable reinforcing member, which is inserted to the fusion spliced optical fiber and covers a fusion spliced point of the fusion spliced optical fiber, to a midpoint of the heating and reinforcing device; a housing provided on the main body and shaped to house the fusion spliced optical fiber and the reinforcing member and align the fusion splicing point and the mid point of the heat shrinkable reinforcing member with each other; and a heater provided in the housing to melt the reinforcing member.
