9. Pulling Cable
9.1 General
Backbone cable is typically a high pair count copper cable (25- to 2400-pair), or high strand count
optical fiber cable. Horizontal cable is typically 4-pair balanced twisted-pair with a performance level
of category 3, 5e, or 6, or 2- to 6-strand optical fiber. For indoor optical fiber cable, the preferred colorcoding
scheme and written nomenclature for premises cable jackets are specified in ANSI/TIA 598-C
(see Table 3). An example of the nomenclature used is that of a 12-fiber cable containing eight 50/125
μm and four 62.5/125 μm fibers. The nomenclature for such a cable may include “12 Fiber — 8 x
50/125, 4 x 62.5/125” in the jacket print statement. For ultraviolet (UV) stabilized indoor/outdoor
cable, the preferred color is black. The City Of San Antonio standard for multimode optical fiber cable
is 62.5/125 μm or unless otherwise identified by the City..
When cable is received at the job site, the cable length should be verified to ensure the cable will reach
between the end points. Inspect both ends of the cable to verify the footage markings on the outer
jacket and compute the actual length of the jacket. The cable shall be identified, labeled, and the as
built updated to reflect the work operation. As built plans shall be provided to the owner as a
permanent record.

9.2 Cable Pulling Setup
9.2.1 Overview
A good cable pulling setup means all materials are in place so the cables can be handled
properly and safely. A cabling contractor may need specialized equipment capable of holding
large reels. Smaller equipment, such as cable trees, may be used to handle the many reels of
cable containing low pair count cable.
The pathway of a cable shall be free of sharp bends and turns. The manufacturer’s
recommended pulling tension and minimum bend radius (while under tension) shall not be
exceeded. The use of cable lubricants can significantly reduce friction and speed cable
