Cabling Guidelines

This appendix provides specifications for cables used with a NETGEAR 700 Series Managed

Switch.

Fast Ethernet Cable Guidelines

Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for 100BASE-TX.The

specification requires Category 5 UTP cable consisting of either two-pair or four-pair twisted

insulated copper conductors bound in a single plastic sheath. Category 5 cable is certified up to

100 MHz bandwidth. 100BASE-TX operation uses one pair of wires for transmission and the

other pair for receiving and for collision detection.

When installing Category 5 UTP cabling, use the following guidelines to ensure that your cables

perform to the following specifications:

Certification

Make sure that your Category 5 UTP cable has completed the Underwriters’ Laboratories (UL) or

Electronic Testing Laboratories (ETL) certification process.

Termination method

To minimize cross-talk noise, maintain the twist ratio of the cable up to the point of termination;

untwist at any RJ-45 plug or patch panel should not exceed 0.5 inch (1.5 cm).
