THE DEVICE FOR THE STACK AND PROTECTION OF THE OPTICAL FIBER

摘要

A device for protecting and storing a laser beam transmission optical fiber is provided to draw out the desirable length of the optical fiber, to prevent the optical fiber from being drooped and twisted, and to reduce damage of the optical fiber by winding the optical fiber around a reel binder. In transmitting a laser beam generated from a laser oscillator(30) to an optical fiber(20) through a beam transmitting unit(31) formed at the laser oscillator, the optical fiber is wound around a cable reel-type binder(10). The reel binder is composed of a first combining unit(11) for joining one end of the beam transmitting unit to the side center of the reel binder; a first bending mirror installed at an inner center axis of the reel binder with communicating with the first combining unit; a second bending mirror mounted at a circular outer contact line of the reel binder to vertically communicate with the first bending mirror; and a second combining unit joined with the optical fiber to vertically communicate with the second bending mirror.
