Cabling Suggestions

When connecting UTP network cables, the following guidelines are suggested for trouble-free operation.

Use CAT 5 Equipment for Future 100Mbps Networks

For true Category 5 compliance, all components including: UTP trunk cables, UTP patch cables, patch panels and modular wall plugs must be CAT 5 certified. A CAT 5 cable certifier may be used to ensure CAT 5 compliance.

Never Exceed a Cable’s Minimum Bend Radius

For Category 5 cables, the cable may not be bent beyond 5 times its own diameter (i.e., 1.25”).

Do Not Exceed the Maximum Tensile Loading

The maximum tensile load is the amount of stress a cable can withstand before performance begins to decline. This level usually occurs far before the breaking point of the cable. Tensile loading is measured in pound-foot (lbf). For 24 AWG Category 5 cables, the maximum tensile loading should not exceed 25 lbf.

Do Not Over-Cinch the Cables

When grouping a set of cables with cable ties, cords, or staples, over- cinching can cause the cable jackets to compress causing a deterioration of cable integrity. Use proper cable clamps or “D” rings which allow for the cable’s width and girth.

Do Not Untwist the Pairs on CAT 5 Cables Beyond 0.5”

Care should be taken to never untwist the pairs beyond 0.5 inches from the point of termination. This rule is in accordance with TIA/EIA-568 guidelines.

Keep UTP Cables Away From Power Lines

A minimum of five inches should be kept from electrical fixtures, such as fluorescent lights, transformers, and other high power devices to avoid possible interference.

Do Not Run Cables Longer Than The Maximum Length

The maximum cable lengths includes all patch cords from node to wall plug and patch panel to hubs.
