摘要： A cantilever type latch having the fixed end on the side of exposing the terminal end surface of the optical fiber is provided on the side of the plug housing. Near the center of the upper surface of the latch, an engaging projection which is to be engaged in the engaging hole formed in the adapter or the receptacle is formed. The engaging projection has the slope which decreases the height toward the fixed end side of the latch, in which the gradient of the slope is nearly equal to or greater than the rotation angle required for the elastic deformation of the latch with the fixed end functioned as the fulcrum. Thereby easy disconnecting of the latch is implemented.

摘要： A method of cutting an optical fiber easily on site such that its end face after being cut slants with respect to its optical axis A twist is applied to at least a portion of the optical fiber. A notch is formed in the coating and the fiber of the optical fiber at the cutting position, and an external force is applied to the optical fiber and cuts the optical fiber at the cutting position. The cutting device includes an optical fiber fixing means that fixes the optical fiber on one side of the cutting position of the optical fiber, optical fiber rotating means that fixes the optical fiber on its other side such that the optical fiber may freely rotate, and a blade that places the notch in the coating and the glass fiber.
