Confusion about Ethernet cables.
Confusion about Ethernet cables.
The defining feature of an Ethernet cable is the RJ45 connector paired with the specific wiring arrangement. The actual material (such as Cat5, 5E, 6, 6A, 7) isn't inherently Ethernet unless the label on the jacket is visible. Without seeing the ends, the label offers little value. Standard Ethernet cables are laid out directly. Cross-over cables differ in wiring and are used to link two devices without a central hub or switch. All 1Gbit devices automatically adjust speed, duplex mode, and cross-over requirements (Auto-MDI-X), making cross-over cables unnecessary except for connecting non-Gbit equipment before 1998.
Not sure if I remember correctly, but most of my patch cables were blue before there was a phase where they turned yellow. Apparently, you usually get to pick the color. For standard Ethernet cables used inside walls, I've seen them in gray—they're neutral and blend in better when surface mounted.
