Abstract: A fiber optic connector for mounting to a cable having a plurality of optical fibers and optically connecting the optical fibers to mating optical fibers, wherein the optical fibers and the mating optical fibers have termini mounted to respective ends thereof. The connector comprises a generally cylindrical plug body, a plug insert and a biasing member. The plug body has a longitudinal axis, a wall defining a central longitudinal passage, and a circumferential groove formed on the outer surface of the wall dimensioned to receive portions of a U-shaped securing staple. The plug insert has a front face and is longitudinally slidably disposed within a first portion of the longitudinal passage for longitudinal movement between an extended position and a compressed position. The insert defines a plurality of termini cavities formed longitudinally through the front face for mounting a plurality of the termini of the optical fibers therein.
