Use plenum-rated commercial Ethernet cables for runs through air-handling spaces, such as drop ceilings used for return air, where CMP or FT6 cable is specified. Use riser-rated cables for vertical runs between floors or through shafts that do not handle circulating air, and follow local code requirements for the installation.

Solid-conductor bulk cables use rigid conductors suited for permanent, in-wall commercial network runs and termination at patch panels, jacks, or other hardware. Stranded patch cables bend more easily, making them well suited for shorter connections between network equipment, AV devices, and wall outlets.

Cat 5e commercial Ethernet cables support up to 350 MHz and are suited to many standard 1-Gigabit connections, while the Cat 6 options are tested to 550 MHz for greater bandwidth capacity. For system planning, use Cat 5e patch cables for shorter equipment connections, and consider solid-copper Cat 6 riser or plenum cable for structured runs where additional network capacity may support future needs.

A crossover cable is appropriate when you need to connect compatible commercial networking or AV equipment directly, without a typical router or switch between the devices. Its different pin configuration supports direct device-to-device connections, so confirm that the equipment calls for a crossover cable rather than a standard Ethernet patch cable.
