3. INSTALLING THE CLOSURE
NOTE: Fiber optic cable is sensitive to excessive pulling, bending and crushing forces. Consult the cable
specification sheet for the cable you are installing. Do not bend the cable more sharply than the
minimum recommended bend radius. Do not apply more pulling force to the cable than
specified. Do not crush the cable or allow it to kink. Doing so may cause damage that can alter
the transmission characteristics of the cable – the cable may have to be replaced.
WARNING: Do not install this unit or work with telephone wiring during a
lightning storm. Telephone lines can carry high voltages from lightning causing electrical
shock resulting in severe injury or death.
CAUTION: The wearing of safety glasses to protect the eyes from accidental injury is
strongly recommended when handling chemicals and cutting fiber. Pieces of glass fiber are
very sharp and can damage the cornea easily.
CAUTION: The wearing of safety gloves to protect hands from accidental injury is
strongly recommended when using sharp instruments.
3.1 Prepare the Express Cable
IMPORTANT: Typical lengths are illustrated. Since the actual application may vary, it is
recommended to route the buffer tubes as they will lie in the closure to determine
actual strip lengths before cutting fibers. Refer to routing illustrations, if necessary.
Step 1 Remove indicated length of cable sheath and armor (where applicable) according
to cable manufacturer’s instructions (Figure 2).
NOTE: Do not expose the bare fibers until after the cable has been placed in the closure end cap.
Step 2 Cut the central strength member of each cable to 15 cm (6 inches) from the sheath
using side cutters.
Step 3 If aramid yarn is present, leave an excess length of yarn (approximately 6 inches)
for additional strain-relieving.
IMPORTANT: To prevent damage to the fiber, remove all uncut express fiber from the tubing using
the universal access tool (p/n UAT2-000 - purchased separately).
