Installation Practices for UTP Only

Sensible installation practices can improve alien crosstalk headroom for first-generation 10Gb/s UTP cabling systems without alien crosstalk compliant cable designs (i.e. 10G 6). These techniques may also be used to increase the channel capacity of legacy category 6 cabling to the level necessary to provide 10GBASE-T applications support for distances up to 55m (although these channels may not meet pending augmented category 6A alien crosstalk requirements). Examples of UTP installation practices that can positively impact alien crosstalk headroom include:

• Do not "comb" or "pinstripe" cables in the first 20 meters
• Separate patch and equipment cords in the first 20 meters
• Avoid tie-wraps
• Use loose Velcro™ wraps only when absolutely necessary
• Use horizontal wire management techniques (e.g. route odd ports to upper management and even ports to lower management)
• Loosely place cables in vertical wire management
• Avoid unusually high port density at the work area and distribution points.
• Reduce maximum conduit fill density to 40%

Implementation of these practices is not required for any augmented category 6A F/UTP (sometimes referred to as ScTP) or category 7 S/FTP (fully-shielded) cabling systems. In addition, these practices do not need to be applied when using augmented category 6A UTP systems, such as those with cable diameter design enhancements that increase cable-to-cable separation.
