3.0 Fiber Preparation
3.01 Remove the minimum length of fiber required to prepare
and splice the fibers.
1" to 2" (depending on cleaver)
3.02 Strip approximately 1 to 2 inches (2.5 to 5 cm) of plastic
coating from the fiber using a mechanical stripper.
Note:
The stripper used should be in good operating
condition to prevent scratches or other damage
to the glass cladding.
3.03 Clean the bare glass by pulling the fiber through an
alchohol soaked lint-free wipe. This will remove any
fragments or dirt remaining on the fiber.
Note:
Do not wipe the fibers more than two times, and
limit the time that the bare fiber is exposed to the
atmosphere.

Note:
The cleaver should be in good operating condition
and used in accordance with the manufacturer’s
instructions. A cleaver that produces cleaved ends
within 2° of perpendicular and free of major defects
is recommended. Dispose of cleaved fiber ends per
company practice.
3.04 Cleave fiber to the length indicated on the chart.
3.05 Check the cleave length using the cleave length gauge on
the Fibrlok Assembly Tool. Adjust the cleaver to provide
the prescribed cleave lengths. Check cleave lengths
periodically during subsequent splicing operations. Do not
allow cleaved end to contact tool.
