Step 14 -Place the caulking compound tube nozzle into the end of the BOF tube.

Inject the caulking compound so that it completely fills a 12.7 mm

(0.5 inch) length of the tube (as a minimum). Carefully work the

exposed loose tube furcation cable buffer tubes around within the

caulking compound so that there are no voids. Arrange the buffer

tubes so that they are approximately centered in the BOF tube. Clean

any excess caulking compound from the tube with a wipe.

Step 15 -Allow the caulking compound to cure for 72 hours.

Step 16 -Using the razor blade, carefully cut off the exposed ends of the loose tube furcation cable buffer tubes even with the end of the BOF tube.

Step 17 -Verify the integrity of each loose tube furcation cable buffer tube in the completed furcation unit:

Insert the 500-micron fiber through each loose tube furcation cable buffer tube until it exits out the other end of the tube.

Step 18 -Connect the furcation unit to a 234 kPa (34 PSI) pressure source using a tube coupler. Maintain the connection for a minimum of 30 seconds. Verify that there is no leakage of air from the furcation unit body.

NOTE: Leakage may be checked by immersing the furcation unit body in water and visually inspecting for air bubbles. The ends of the loose tube furcation cables should not be immersed.
