A 305 meters drum of CAT6e Cable. The mainstream adoption of Gigabit Ethernet (1000BASE-T) required new industry-standard cables capable of transmitting at a higher frequency of 250 MHz. Category 6 cable uses thicker-gauge wire, increased shielding, and more pair twists per inch to reduce signal noise and interference.
A 305 meter drum of CAT5e Cable. An improved specification to Category 5 was later introduced. By reducing noise and signal interference, Category 5e was capable of increasing rated transfer speeds to 350 Mbit/s over 100 meters.
