A Brief Introduction to Cat6 vs Cat6a vs Cat7

To put it simple, the twisted pair specifications: Cat6 (Class E), Cat6a (Class EA), and Cat7 (Class F) all support 10GBASE-T applications with differentiated performances.

Check the below chart to get a full understanding of the specifications and typical applications of Cat6 vs Cat6a vs Cat7.

  • Cat6 supports 10BASE-T, 100BASE-TX, 1000BASE-T, and 10GBASE-T standards, frequencies up to 250 MHz, and it can handle up to 10 Gbps in conditions of throughput with the utmost cable length of 55 meters.
  • Cat6a is a 10 Gigabit Ethernet over Copper proposal to the Cat6 standard. Cat6a cable is designed to support frequencies of up to 500 MHz, twice that of Cat6, which can support up to 100 meters when transmitting 10Gbps.
  • What is Cat7? Cat7 cable supports transmission frequencies of up to 600 MHz. It supports 10GBASE-T Ethernet over the full 100 meters featuring improved crosstalk noise reduction.
