Abstract: A system and method for removing a predetermined length of coating from a fiber optic cable. The system includes a chemical bath, and a system for forming a loop in a fiber optic cable. The loop forming system includes a vertical column, and a slide arm having a guide collar portion slidably provided on the vertical column, and a distal portion extending away from and integral with the guide collar portion. The loop forming system further includes a mount shaft extending from and connected to the distal portion of the slide arm, the mount shaft having clamps and a tensioning spring for retaining portions of the fiber optic cable. A push rod movably extends through the mount shaft, and connects to a fiber optic cable loop former. The fiber optic cable loop former engages a surface of the mount shaft and is pushed away therefrom by the push rod during formation of the loop in the fiber optic cable.

Abstract: A fiber optic cable stripping and measuring apparatus that includes a mounting base having a template clamp connected thereto, the template clamp securing an optical component connected to the fiber optic cable. The apparatus further includes a fiber clamp connected to mounting base for securing a first portion of the fiber optic cable. A pair of fiber take up mandrels are provided adjacent to the fiber clamp for winding excess fiber optic cable, if excess cable is desired. The apparatus also includes a fiber stripper, spaced from take up mandrels, for scoring a buffer layer of the fiber optic cable. The fiber stripper enables the buffer layer of a portion of the fiber optic cable to be removed to expose optical fiber within the fiber optic cable. The apparatus further includes a cylindrical marking mandrel spaced from the fiber stripper and having a circumference that exceeds the minimum bend radius of the fiber optic cable.

Abstract: An apparatus for managing and measuring fiber optic cable includes a mounting base for receiving and retaining a variety of fiber cassettes capable of holding optical components having fiber optic cables emanating therefrom. The apparatus includes a pair of interchangeable marking mandrels spaced from the fiber cassette and having circumferences that exceed the minimum bend radius of the fiber optic cables. Each marking mandrel has marking grooves formed on its periphery so that the fiber optic cable may be marked at a predetermined location for future splicing of the cable. The apparatus further includes fiber take up mandrels connected to the mounting base, each fiber take up mandrel having a circumference that exceeds the minimum bend radius of the fiber optic cables. The marked fiber optic cables may be temporarily wound around the circumference of the fiber take up mandrels to prevent entanglement and keep the fiber out of the operator's way while another cable is being marked.
