The invention discloses an optical-fiber collator suitable for an electric power communication device. The optical-fiber collator comprises a hollow circular plate, wherein four optical-fiber positioning apparatuses are installed on the front side surface of the hollow circular plate at equal angles along the axis, a rotating block is arranged in a circular hole of the hollow circular plate, the upper surface of the rotating block is connected with the lower surface of a first U-shaped clamping seat by virtue of an elastic apparatus, a clamping groove of the first U-shaped clamping seat is connected with the side edge of the circular hole of the hollow circular plate in a clamping manner, the lower surface of the rotating block is fixedly connected with the upper surface of a second U-shaped clamping seat through a length adjusting device. The optical-fiber collator suitable for the electric power communication device is rapid for sorting the optical fibers, so that the working efficiency of workers can be improved; and the worker connects a slide hole on a movable plate with the side surface of a vertical plate in a sliding manner, the movable plate contacts the optical fibers, and the worker sleeves an elastic rubber ring on the movable plate and the positioning plate so as to fix the optical fibers, so that the tidiness of the optical fibers is good, and the intertwining condition of a plurality of optical fibers can be avoided.
