Prepare fiber-optic premises distribution cable for termination

July 1, 1996
Most cabling installers are familiar with how to prepare 4-pair copper cable for termination, but many are unfamiliar with termination procedures for fiber-optic premises distribution cable. As fiber-to-the-desk becomes more prevalent, it will be necessary for installers to learn to handle fiber cable as proficiently as they do copper.

Problem

Most cabling installers are familiar with how to prepare 4-pair copper cable for termination, but many are unfamiliar with termination procedures for fiber-optic premises distribution cable. As fiber-to-the-desk becomes more prevalent, it will be necessary for installers to learn to handle fiber cable as proficiently as they do copper.

Solution

Fiber-optic premises distribution cable can be prepared for termination using the following simple procedure.

Procedure

Remove several inches of the cable`s outer jacket by using a cable slitter or utility blade. Be careful not to damage the cable core.

1) With hands or pliers, grasp the aramid ripcord or ripcords one at a time and pull, splitting and peeling the jacket off as you would peel a banana.

2) Cables with higher fiber counts will contain subunits within the outer jacket. If there are subunits, cut completely around each subunit jacket with a small cable slitter or blade, again being careful not to damage the tight-buffered fibers inside.

3) Remove the cut piece of subunit jacket. Trim aramid with aramid scissors, if necessary.

4) For clean, fast, cost- effective buffer removal, mechanically strip off the fiber`s acrylate coating. The one-step stripping procedure, performed with tools from Sumitomo or Klein Tools, removes the buffer and coating in one motion.

5) Break-out kits are only required for premises distribution cables if the cables are kept unprotected in high-traffic areas or if many connection changes are anticipated. Standard connectors can be fitted directly onto a 900-micron tight-buffered fiber.
