Appendix E: UTP Cabling

This appendix discusses various aspects of connection media. The RCS system

utilizes UTP cabling. The performance of an switch system depends on high

quality connections. Poor quality or poorly installed or maintained cabling can

diminish switch system performance.

NOTE: This appendix is for information purposes only. Please consult with

your local code officials and/or cabling consultants prior to any installation.

UTP Copper Cabling

The following are basic definitions for the three types of UTP cabling that the

RCS supports.

• CAT 5 (4-pair) high performance cable consists of twisted pair conductors,

used primarily for data transmission. The twisting of the pairs gives this

cable some immunity from the infiltration of unwanted interference. CAT 5

cable is generally used for networks running at 10 or 100 Mbps.

• CAT 5E (enhanced) cable has the same characteristics as CAT 5, but is

manufactured to somewhat more stringent standards.

• CAT 6 cable is manufactured to tighter requirements than CAT 5E cable.

CAT 6 has higher measured frequency ranges and significantly better

performance requirements than CAT 5E cable at the same frequencies.

Wiring Standards

There are two supported wiring standards for 8-conductor (4-pair) RJ-45

terminated UTP cable: EIA/TIA 568A and B. These standards apply to
