Cabling
Choose a cable by what it connects: Direct-Attach Cables holds copper cables that join switch, server and storage ports directly at 10G and faster, breakout versions included, while the console cables page covers the serial cables used to manage switches and routers. Cables that join stacked switches into a single unit are listed under Stacking Cables.

Which cable for which link
Pick the cable by the link it has to make, then by speed and length:
| Link | Cable class | Where to shop |
|---|---|---|
| Switch, server or storage ports within a rack or the next one, 10G and faster | Direct-attach copper (DAC), straight or breakout | Direct-Attach Cables |
| Runs longer than a copper cable reaches | Optical transceivers plus fiber | Optical Transceivers |
| Joining stacked switches into one unit | Stacking cables for the switch's stacking system | Stacking Cables |
| Managing a switch or router from its console port | Console cables | Console cables |
Cisco lists its passive SFP+ copper cables at 1 to 5 m and its active ones at 7 and 10 m, so a link past 10 m calls for optical cabling.
