Abstract: An optical fiber fixing device has a V-grooved block, a clamp mechanism, a stopper mechanism, a sensor, a motor, an operator section and a controller. The V-grooved block has a top surface formed with a V-groove to support an optical fiber thereon. The clamp mechanism has a clamp portion to fix the optical fiber on the V-grooved block. The stopper mechanism retains the clamp mechanism before the clamp portion is brought into contact with the optical fiber. The sensor outputs a detection signal to the controller upon detection of the clamp mechanism being brought into contact with the stopper mechanism. Upon receipt of that signal, the controller drives the motor to lower the stopper mechanism. In sequential operation with downward movement of the stopper mechanism, the clamp portion presses the optical fiber against the V-groove to fix the optical fiber in place between the clamp portion and the V-grooved block.

Abstract: An optical fiber cable covering removing device which can remove the covering layer of an optical fiber reliably and safely comprises a support member, a fiber holder, a fiber holder retainer which can move the fiber holder toward and away from the support member along the longitudinal direction of the optical fiber. The support member is provided with a cutter holder fixing structure which fixes cutter holders in closed position. The cutter holder fixing structure is disposed so as to be able to impart force to the first cable covering removing cutter and the second cable covering removing cutter formed on the cutter holder in parallel. The fiber holder retainer is provided with a fiber holder fixing structure which fixes the fiber holder in a closed position. The fiber holder fixing structure is disposed near the center of the fiber holder.
