Cabling Practices
E.1. Introduction
This appendix includes recommended cabling practices that should be followed in order
to avoid potential hazards and to achieve proper operation of your MTAS -192 Metallic
Test Access System.
E.2.
General Cabling Rules
1. Avoid running cables parallel to power cables.
2. Do not bend cables to less than four times the diameter of the cable.
3. When bundling groups of cables together (using cable ties, zip ties, etc.), snug
the cables together firmly, but do not over-cinch them or deform the cables.
4. Keep cables away from devices which can introduce electrical noise (e.g., copy
machines, electric heaters, speakers, printers, televisions, fluorescent lights,
welding machines, microwave ovens, telephones, fans, elevator motors, electric
ovens, dryers, washing machines, shop equipment, etc.).
5. Avoid stretching unshielded twisted pair (UTP) cables. If this is unavoidable, the
strain (force) on the cable must not exceed 25 lbs.
6. Never run UTP cable to the outside of a building. This presents a very
dangerous lightning hazard.
7. Never use a stapler to secure UTP cables. Instead, use telephone wire hangers
(which are available at most hardware stores).
8. Avoid reusing old cables.
E.3.
CAT5 Cable Types: Stranded vs. Solid
Most patch cables have stranded wire. Stranded wire is normally specified for use in
patch cables due to its superior flexibility. There are debates (in the technical sector of
the structured wiring community) regarding the possible use of solid conductors for
patch cables because it is supposedly more stable under a variety of conditions.
NOTE: Comtest offers custom solid copper category 5E patch cables in Plenum
insulation in lengths of up to 295 feet. These cables are suitable for use in air handling
(Plenum) ceilings and environments.
