Optical fiber connection tool and optical fiber connection method

Abstract

An optical fiber connection part (5), comprising a ferrule (7) and a connection mechanism (10) having two clamp parts (18) and (19), wherein an existing optical fiber (6) and a newly installed optical fiber (17) are clamped by one clamp part (18) in butt-jointed state and the other clamp part (19) clamps the newly installed optical fiber (7). An optical fiber connection tool (1), comprising two open / close members (2) and (3) operable independently of each other. An optical fiber connection method, comprising the step of, when fitting the optical fiber connection part (5) to the tip part of the newly installed optical fiber (17), after extracting one open / close member (2) from one clamp part (18), extracting the other open / close member (3) from the other clamp part (19), whereby a deflection caused at the butt-connected part of the optical fiber can be relieved to prevent a transmission loss from increasing and a damage to the optical fiber.

Description

field of invention [0001] The present invention relates to an optical fiber connection tool and an optical fiber connection method, in particular to an effective optical fiber connection tool for connecting an existing optical fiber on an optical fiber connection part and a new optical fiber separated from the existing optical fiber through a connection mechanism of the optical fiber connection part, and Fiber connection method. Background technique [0002] In recent years, regarding an optical fiber connector that can be easily installed on the front end portion of an optical fiber, the following has been disclosed: it has a ferrule in which an optical fiber is inserted in a central portion, and a connection provided on the end of the ferrule. mechanism. [0003] At this time, the connecting mechanism has: a two-split connecting element formed by combining two split parts, and a clamp spring (clamp spring) installed on the outside of the connecting element while applying ...

AI Technical Summary

Problems solved by technology

[0007] However, for the above-mentioned optical fiber connection tool, due to the butt force of the newly established optical fiber relative to the existing optical fiber on the optical fiber connector side, bending will occur at the front ends of the two optical fibers. The optical fiber will cause increased loss due to the bending of the optical fiber and damage to the front end of the optical fiber due to the stress concentrated on the bent end portion of the two optical fibers. These are the causes of poor contact.
