Step 3 - Insert the loose tube furcation cables into the polyethylene tube and slide the tube approximately 30 cm (12 in) down the furcation cables.

Step 4 - Using the OFCC strip tool, trim back the loose tube furcation cable jackets approximately 100 mm (4 in) exposing the kevlar and buffer tubes. Arrange all of the loose tube furcation cables together and evenly align them with each other (see figure 2E1-1).

Step 5 - Slide the polyethylene tube up the loose tube furcation cables until it is approximately 25 mm (1.0 inch) from the end of the furcation cable jacket. Ensure that the trimmed portions of the loose tube furcation cables are still aligned with each other.

Step 6 - Thoroughly mix the two parts of the epoxy together and apply the epoxy to the end 19 mm (0.7 in) of the loose tube furcation cable jackets.

NOTE: Only a light coating of epoxy is required. Make sure that epoxy is applied to all furcation cable jackets.

Step 7 - Carefully move the polyethylene tube over the epoxy covered loose tube furcation cables until the ends of the furcation cable jackets are centered approximately between the ends of the polyethylene tube.

Fold back the kevlar strands over the polyethylene tube (see figure

2E1-2).

Step 8 - Still holding the loose tube furcation cable and polyethylene tube assembly, insert the exposed furcation cable buffer tubes into the BOF tube. Slide the BOF tube to the edge of the polyethylene tube.

Step 9 - Apply epoxy to approximately 19.0 mm (0.75 inch) of the BOF tube end closest to the polyethylene tube. Insert the BOF tube into the
