ABSTRACT:
An optical fiber connecting tool is provided in which an optical fiber connecting tool5is used which has a ferule7,a connecting structure10which has two clamping sections18, 19which are disposed in a ferule7.A pre-installed optical fiber6and a newly installed optical fiber17are clamped in a butt-connected condition by a clamping section18.The newly installed optical fiber17is clamped by the other clamping section19.An optical fiber connecting tool1is provided which has an open/close member2which is detachably disposed on the clamping section18and another open/close member3which is detachably disposed on the another clamping section19such that the both of the open/close members2, 3can be operated independently. Also, a method for connecting optical fibers according to the present invention prevents an increase in a loss due to a bent optical fiber and a damage in the optical fiber by extracting the open/close member2from the clamping section18before extracting the open/close member3from the another clamping section and dispose a deformation which is generated on the tip section of the optical fiber when the optical fiber connecting part is attached on the tip section of the optical fiber according to steps for performing an extracting operation for the open/close member e from the another clamping section. Here, for the optical fiber connecting part, for example, various members can be adapted such as a member which does not have the above explained ferule, and a member which realize a connection and a clamping operation for the optical fibers by a structure of only the above explained connecting structure.
