Abstract
A fusion-splicing device is provided. The fusing-splicing device includes a fusion-splicing operation unit that fuses respective exposed ends of another optical fiber and a built-in optical fiber to form a spliced fiber. The fusion-splicing device further includes a fusion-spliced-portion reinforcement device that receives said spliced fiber.
Claims11
A fusion-splicing device for fusion-splicing an exposed end of a built-in optical fiber affixed to a ferrule to an exposed end of another optical fiber, the fusion-splicing device comprising:
- a fusion-splicing operation unit that fuses the respective exposed ends of said another optical fiber and the built-in optical fiber to form a spliced fiber, the fusion-splicing operation unit receiving and holding a ferrule holder in a prescribed position, said ferrule holder receiving and holding said ferrule at one end that is opposite to an end having said exposed end of the built-in optical fiber, and having a stem of a prescribed length at an opposite end, said fusion-splicing operation unit further receiving said another optical fiber such that said respective exposed ends of the built-in optical fiber and said another optical fiber face each other at prescribed positions;
- and
- a fusion-spliced-portion reinforcement device that receives said spliced fiber having, on one end, said ferrule attached to the ferrule holder,
- wherein at least a portion of the stem of the ferrule holder extends, and is exposed to an exterior, from one end of the fusion-spliced-portion reinforcement device to be manually accessible when said spliced fiber is received by the fusion-spliced-portion reinforcement device.

A fusion-splicing device, comprising:
- a fusion-splicing operation element that fuses ends of opposing optical fiber segments to form a spliced optical fiber;
- and
- a ferrule holding device that receives and holds a ferrule holder in a predetermined position, said ferrule holder having an open end that receives a cylindrical portion of a ferrule therein and having a stem at an opposite end thereof, wherein
- said ferrule has an optical fiber segment that extends away from said open end of said ferrule holder when said ferrule is disposed in said ferrule holder,
- one end of the ferrule holding device is open to allow an end of the optical fiber segment of the ferrule to be held at a position to be fused to an end of an opposing optical fiber,
- an opposite end of said ferrule holding device is shaped to accommodate the stem, and
- at least a portion of the stem of the ferrule holder extends, and is exposed to an exterior, from the opposite end of the ferrule holding device to be manually accessible so as to permit transferring the ferrule to and from the ferrule holding device while the cylindrical portion of the ferrule is held by the ferrule holder.
