3M II 2529 manual Fiber Organization and Splice Storage

5.04Hold the cap lifter in place with one hand and push down on the ends of the splice with the other hand. This action should reseat the splice into the holding cradle and lift the cap at the same time.

5.05Repeat fiber centering and splice actuation (See step 4.06 – 4.09.) If after two attempts an acceptable splice loss is not obtained, remove fiber, strip, clean and re-cleave. Re-splice using a new splice.

6.0Fiber Organization and Splice Storage

6.01When storing fiber slack in a splice tray, the spliced fiber ends will twist one full turn for each full loop of fiber being stored. This rotation places stress on the fibers. This rotational stress

makes fiber organization more difficult and may affect fiber/ splice performance, particularly in 900 Šm coated fibers. The stiffness of the 900 Šm fiber does not distribute this stress in the same manner as 250 Šm coated fiber. The following procedure is strongly recommended when splicing 900 Šm coated fibers and will improve fiber organization when splicing all fiber types.

6.02Secure the buffer tubes of the fibers to be spliced to the tray so that the fibers are free to rotate through the point of attachment.

6.03Select the first two fibers to be spliced and lay them into the tray. Trim the fibers so they are the right length for splicing plus approximately 1 to 2 inches (2.5 to 5 cm) for fiber end preparation.

6.04Place the splice assembly tool close to or on top of the splice tray. Match the orientation of the tool to that of the splice holder or tray whenever possible.
