Unterminated Cable
Installation Guidelines
Publication 1756-TD008A-EN-P - August 2002
If you pull unterminated cable, pull it prior to connector installation; it
becomes more difficult to protect fiber from stress after connectors
have been mounted. Connectors may be pre-installed on one end,
leaving the other end for pulling. Refer to the cable specifications and
manufacturer's cable pulling instructions for additional information.
Cables should be lubricated prior to pulling to minimize the pulling
forces on the cables. Lubricants such as waxes, greases, clay slurries,
and water-based gels are compatible with most fiber optic jacket
materials.
It is necessary to identify the strength member and the optical fiber
location within the cable. Afterwards, a decision should be made to
choose a cable pull method - pull or indirect attachment to make sure
effective pulling without fiber damage. Never pull the cable by the
fiber strand.
Direct Attachment
The cable strength member is attached directly to a pulling eye. Since
epoxy glass central strength members are too rigid to tie, they may be
secured to the eye using tight clamping plates or screws.
Indirect Attachment
Indirect attachment uses a pulling grip attached to the cable's outer
jacket to distribute the pulling force over the outer portion of the
cable. The pulling grip produces the least amount of stress in cables
where the strength member lies directly beneath the jacket.
