Step 1 - Using the kevlar shears, cut the required number of loose tube furcation cables to the required length.
NOTE: Slate colored loose tube furcation cable is used for furcation units for multimode optical fiber. Yellow colored loose tube furcation cable is used for furcation units for single mode optical fiber.
NOTE: The exact length of the loose tube furcation cable depends upon the equipment and the furcation cable routing. This length may be determined by measuring the distance required to route the loose tube furcation cables from the end of the BOF tube to the furthermost connection point in the equipment plus approximately 130 mm (5 in). Alternatively, standard length furcation units (1.0 m, 1.5 m, 2.0 m, etc.) may be fabricated and cut to the appropriate length during equipment installation.
Step 2 - Using the tube cutter, cut the following items to the identified lengths:
a. 38.0 mm (1.5 inch) length of polyethylene tube. b. 76.0 mm (3.0 inch) length of BOF tube.
c. 76.0 mm (3.0 inch) length of heat shrink tubing.
NOTE: Clean the end of the polyethylene tube and the BOF tube with a wipe dampened with alcohol and blow dry as necessary.
