The term “drop” refers to the connec-
tion of the main cable system from the
tap to 5-10 homes or to one or several
Multiple Dwelling Units (MDUs).
Experience has shown that the most
common sources of leaks are drop
related. Although drop related leaks
are the most abundant, leaks from the
trunk and distribution equipment may
be more serious. For example, a leak
emanating from trunk or bridger out-
put is likely to radiate greater RF ener-

What
to look for?
Splices and Fittings A mechanical/electrical connection to
join two wires or cables together.
Water and weather can
result in pulled-out,
sucked-out, loose or
corroded fittings.
Splices at Taps,
Line-Extenders,
Splitters,
Amplifiers, and
Ground Blocks
Refer to the Glossary of Terms found
in Appendix E for the following defi-
nitions: Tap, Line-Extenders, Splitters,
Amplifiers, and Ground Blocks.
Check for bad connec-
tions, connectors and/or
terminators. Look for
worn or damaged
cable. Also check for
poor craftsmanship
which resulted from
using poor quality
materials and poor
quality installation.
Cable, Distribution
Equipment
One or more electrical or optical con-
ductors found within a protective
sheathing. When multiple conductors
exist, they are isolated from each other.
Check for cable cuts,
breaks and exposure.
Illegal Hook-ups Cable hook-ups completed by unau-
thorized cable system personnel.
Check for twin leads
inferior passive devices,
poor or no connectors,
and improperly termi-
nated splitters. Also
check for jumpers from
drops to taps and/or
ground blocks. Center
conductors stuck into tak
spigots. Drops should
have no splices in them.
(note that weather boots or heat
shrinks should be used when replac-
ing jumpers on splices)
