Black Box Explains...Type 1 vs. Type 6 Cable
Type 1 Cable is made of solid wire, typically 22 AWG bare copper. It has braided shielding around each pair. It’s recommended for long runs in walls, conduits, etc.
Type 6 Cable is typically made of 26 AWG stranded copper and has one shield around both pairs. It’s lighter and more flexible than Type 1 Cable and has a better “look.” It’s recommended for use in office environments.
