Network cabling is always subject to distance limitations, which depend on the media used and the bandwidth supported. Table A-2 provides a quick reference by listing the maximum cabling distance of a variety of network media and cable types.

[1] UTP = unshielded twisted-pair

[2] STP = single twisted-pair

[3] When using 1000BASE-LX/LH GBICs with 62.5 micron multimode fiber, you must use a mode-conditioning patch cord for distances of more than 300 m (984 ft). See www.cisco.com/univercd/cc/td/doc/product/lan/cat5000/cnfg_nts/ethernet/5421_01.htm for installation and usage information.

[4] SMI = single-mode intermediate reach

In many cases, you might find that you need to know the pinout connections for various network cables. The RJ-45 connector is commonly used across many media, but with different pinouts for each. Table A-3 shows the pinout for an RJ-45 connector when used with specific media.
