Cat 5e cabling solutions support up to 350 MHz and 1-Gigabit Ethernet, making them suited to standard data, audio, and video connections. Cat 6 solutions support up to 550 MHz and 10-Gigabit Ethernet, so they can better fit projects that call for higher network performance, tighter rack organization, or Cat 6 patch-panel terminations.

Use a crossover cable when connecting two computers or compatible AV and networking devices directly without a router or switch, because its pin configuration differs from a standard Ethernet patch cable. Use a standard patch cable for typical connections between devices and a router, switch, patch panel, or wall outlet.

Plan for a standard rack width and hole spacing, a one-rack-unit mounting space, and access to the front RJ45 jacks and rear 110 punch-down terminals. Use color-coded terminations that follow either TIA/EIA 568A or 568B, then select patch cables with suitable lengths and snagless boots to support clean routing and easier service.

Choose cable lengths that provide enough reach without leaving excessive slack, and select standard RJ45 patch cables for typical connections or crossover cables for direct computer-to-equipment connections that bypass a router or switch. For rack distribution, choose a Cat 6 patch panel with 24 or 48 ports based on current connections and planned expansion, using its 110 punch-down terminals with the applicable TIA/EIA 568A or 568B wiring scheme.
