Abstract
An optical fiber plug comprises a guide sleeve, a sleeve arranged in the guide sleeve and oppositely mounted at one end of the guide sleeve, and a chuck arranged at the other end of the guide sleeve opposite to the sleeve and fixedly connected with the guide sleeve, wherein the sleeve and the chuck are respectively used for guiding and clamping optical fiber; a tapered hole is formed at one end of the sleeve, or one end of the sleeve is made into an inner tapered surface; and a guide hole is formed on the guide sleeve in a position corresponding to the tapered surface on the sleeve. The tapered hole or the inner tapered surface is formed at one end of the sleeve; when transmitted through the optical fiber, the laser, which is propagated in the sleeve and leaks from the optical fiber, is reflected from the sleeve through the tapered hole or the inner tapered surface on the sleeve, and is led out of the sleeve through the guide hole on the guide sleeve sleeved on the sleeve, so as to effectively and rapidly cool the sleeve, avoid the excessive heating of the sleeve caused by laser leakage, and further protect the sleeve and other components against damage caused by the laser leakage.
