Abstract
A method of fusion-splicing includes attaching a stab to a stub cap having a non-axisymmetric structure, positioning an embedded optical fiber to a fusion splicing working part by fixing the stub cap thereto; positioning an outside optical fiber to the fusion splicing working part; fusion-splicing the embedded optical fiber and the outside optical fiber; repositioning the embedded optical fiber to a reinforcing working part by fixing the stub cap thereto and repositioning the outside optical fiber to the reinforcing working part such that a relative positional relationship between the embedded optical fiber and the outside optical fiber becomes the same as that at the fusion splicing working part; and reinforcing a spliced portion between the embedded optical fiber and the outside optical fiber while a tension is applied to the embedded optical fiber and the outside optical fiber.
