MIL-STD-2042-2B(SH)
NOTE: Do not pull slack fiber bundle out of the BOF tube while breaking out the bundle fibers. If slack fiber bundle is accidentally pulled out of the BOF tube, re-establish the bundle to its original position (using the mark on the bundle jacket) and continue the procedure.
c. Using the bundle jacket stripper, remove the bundle jacket in approximately 160 mm (6 inch) lengths back to the mark.
NOTE: Once a short length of the bundle jacket has been removed, the remaining length can be torn off of the bundle by hand.
d. Using the clear jacket stripper, remove approximately 80 mm (3.0
in) of the clear inner jacket from the end of each 6-fiber subunit.
NOTE: If the clear jacket stripper does not bite into the clear inner jacket, position the clear jacket stripper at a 30 to 40 degree angle to increase its bite.
e. Find the ripcord from among the six fibers. Ensure that it is not crossed with any of the fibers. While holding the group of fibers in one hand, pull the ripcord along the bundle with the other hand. Pull the ripcord until it reaches the mark on the bundle jacket.
NOTE: The ripcord and fibers spiral along the bundle length. Take care to follow the spiral when pulling the ripcord.
f. Starting at the end of the fiber bundle subunit, carefully pull the group of fibers from the clear inner jacket.
g. Using the scissors, carefully cut away the ripcord and the clear inner jacket.
Step 4 - Using the tube cutter, cut a piece of BOF tube a minimum of 80 mm (3 inch) in length. Visually verify that both ends of the tube are cut perpendicular to the tube length. Clean the ends of the BOF tube with a wipe dampened with alcohol and blow dry as necessary.
NOTE: When tube furcation units with removable BOF tubes are utilized, the removable tube from the tube furcation unit may be utilized as the 80 mm (3 inch) BOF tube.
Step 5 - Insert the individual fibers into the short piece of BOF tube. Slide the short piece of BOF tube over the fibers to within approximately 51 mm (2.0 in) of the tube coupler.
Step 6 - For tubes containing BOF bundles only:
a. Place the appropriate tapered tube plug around the exposed bundle jacket approximately 19 mm (0.75 inch) from the BOF tube coupler.
NOTE: The tapered tube plug should be oriented with the tapered end of the plug towards the short piece of BOF tube.
b. Push the short piece of BOF tube over the tapered tube plug until the plug is fully inserted into the BOF tube.
NOTE: Do not pull slack fiber bundle out of the BOF tube while assembling the plug to the bundle jacket and the short piece of BOF tube. If slack fiber bundle is accidentally pulled out of the BOF tube, re- establish the bundle to its original position and continue the procedure.
Step 7 - For tubes containing individual BOF fibers only:
