4.3 Locating the Reversal Point
Once the outer sheath has been removed
the cable core is exposed. The cable core
consists of color-coded buffer tubes
stranded around a dielectric central
strength member. The buffer tubes are
secured by binder strings. Water absorbent
tape or yarn encloses the buffer tubes and
the central strength member. Layers of
flame barrier tape and fiberglass outer
strength members complete the assembly.
Cut the outer strength members at the
center of the section and secure them away
from the core.
Unwrap, cut, and discard the flame barrier
tape and water absorbent tape. Leave the
binder strings intact at this time.
Locate the buffer tube reversal point by
scanning the exposed cable core. Once the
reversal is found the location of the
midspan length can be determined. Refer
to manufacturer’s closure documentation
for specific lengths of cable to be accessed.
For most applications, an 80 inch (200 cm)
section of exposed cable core should be
sufficient. Measure off half of the
recommended distance or 40 inches (100
cm) in each direction from the reversal
point and mark the cable. By orienting the
reversal point at the center of midspan of
the cable, the buffer tubes can be properly
unwound. Remove the sections of cable
sheath between these marks. Refer back to
section 4.2 for sheath removal procedures.
