Swivel Pulling Eyes on Fiber Optic Cable
manufacturers install special strength members,
yarn (DuPont Kevlar), for pulling. Fiber optic cable
should only be
pulled by these strength members unless the cable
design allows pulling
by the jacket. Any other method may put stress on the
fibers and harm
Swivel pulling eyes should be used to attach the
pulling rope or tape to the cable to prevent cable
twisting during the pull.
Procedure for installing pulling eyes:
Strip the cable jacket and cut back all fibers to the
end of the jacket, leaving the aramid stregth members
Separate the aramid yarn into two bundles and loop it
through the swivel eve in opposite directions.
Tie knots in each bunch at the eye and loop the
strength members back to the cable jacket.
Tape the strength members along the jacket and up to
the pulling eye.
