The invention relates to the field of fiber processing, and provides a fiber ceramic insertion core tail handle for the purpose of effectively preventing fibers from falling off. The fiber ceramic insertion core tail handle disclosed by the invention comprises an optical cable with the fibers being stripped, and a ceramic insertion core and a tail seat which are connected in a sleeved mode. The optical cable with the fibers being striped is inserted into a space reserved by the ceramic insertion core and a shaft in the fiber ceramic insertion core tail handle and is fixed through casting glue. The optical fiber with the fibers being stripped, which is fixed in the tail seat, is an optical cable whose optical cable fiber skin is provided with a recess. According to the invention, through arranging the recess in the optical cable, the fiber ceramic insertion core tail handle is provided with a convex ridge as a bayonet, the tail seat is crimped with and is in interference fit with the ceramic insertion core, based on this, through glue perfusion and high-temperature solidification, at the time when a glue amount is increased, the solidified glue can form an enclosed fixation sleeve among the optical cable, the tail seat and the ceramic insertion core, and the press mark of the optical cable is reversely hooked on the solidified 353ND glue in a step form, such that when reliability tests such as high temperature and high moisture, TC, tension tests and the like are carried out, the problem that the optical cable falls off is radically prevented, and the reliability index of the optical cable is improved.
