What You Need to Know about Cat 6A Cable

cabling.jpg Cat 5 specifies four-pair cable consisting of twisted-pair conductors used mainly for digital transmission. Cat 5 cable is typically deployed for full-duplex Ethernet networks running at 10 or 100 Mbps. See All in Enterprise Networking » If you’re looking to the future, Cat 6A will deliver the best performance at the full distance. If, however, you have no cable length requirements over 120 to 150 feet, then Cat 6 will support 10 Gbps.Tags:News & ViewsCat 6AWi-Fi 6Enterprise NetworkingNews & Views Articles You Might Like ‘Snowflake’ Networks: Putting a Freeze on Automation Terry Slattery June 26, 2019 Snowflake networks may sound as pretty as a new snowfall, but they create real challenges for automation. Wired vs. Wireless: A Closer Look J.R. Simmons September 18, 2019 As enterprises configure their networks to meet the demands of a connected workforce, the debate over wired vs. wireless network has come into focus. Cat 6 has a tighter twist in the cables, which supports two-way communication on each pair of wires. Cat 5e doesn’t support this feature. Cat 5e and Cat 6 support 1-Gbps networks. Cat 5e may have a longer delay, which makes it seem that it’s running more slowly. Especially as they build up their Internet of Things environments, businesses will need three things in the near future: greater LAN speeds, higher power levels for PoE ports, and more connections. Greater speed and higher PoE means new cabling technology — enter Category 6A twisted-pair copper cabling. Knowing the Difference in Cabling StandardsCat 3 cable, also known as voice-grade, or VG (as in 100BaseVG), is an unshielded twisted-pair (UTP) cable used to connect legacy telephones. It’s one of the copper cabling standards defined and specified jointly by the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA) and published in TIA/EIA-568-B. Cat 3 can reliably support data rates up to 10 Mbps for Ethernet connections. Businesses can expect Cat 6A cabling to cost at least about 20% more to implement than Cat 6, but when you consider the growth in devices powered by PoE and in the number of wireless users, it’s more difficult than ever to make a case for implementing anything lower than Cat 6A. Not selecting Cat 6A could put businesses at risk of needing to replace Cat 5e and Cat 6 cabling in order to support 802.11ax APs. 5 Things You Probably Don’t Know About Extreme Networks Zeus Kerravala May 17, 2019 The company, whose existence was being questioned just a few years ago, has risen from the proverbial ashes. Introduction to 802.1axIEEE 802.11ax, marketed as Wi-Fi 6 by the Wi-Fi Alliance, is one of the two Wi-Fi specifications standards of IEEE 802.11. The other is 802.11ay, which has more problems penetrating surfaces like walls than does the ax version (see related No Jitter post, “Cisco Goes Big with Wi-Fi 6.” Cat 5E cable is designed to support full-duplex Fast Ethernet (100 Mbps) operation, as well as Gigabit Ethernet. In addition, Cat 5e has stricter specifications for crosstalk, attenuation, and return loss than Cat 5. Here Comes Cat 6ATo reduce crosstalk, Cat 6A has additional and tighter twists and insulation than previous versions. Cat 6A is backwards-compatible with Cat 6 and Cat 5E; the speeds are limited, and will perform to the lowest-category cable or connector installed in the link. Cat 6A is the cabling expected to support the new Wi-Fi 6 APs. 802.11ax access points (APs) are designed to operate in all-band spectrums between 1 and 7 GHz, when they become available, in addition to the existing 2.4- and 5-GHz bands. Device vendors have demonstrated a top speed of 11 Gbps. Throughput speeds are four times higher than they are for IEEE 802.11ac, even though the nominal data rate is about 37% faster at most with latency down 75%. Connecting the new APs will require higher-speed cabling (10 Gbps) and new LAN switches. 8 Disruptive Forces Reshaping Networking Sorell Slaymaker September 05, 2019 Change is in the air, and not all long-held assumptions will prove valid. Cat 6 cable provides higher performance than Cat 5e and features more stringent specifications for crosstalk and system noise. To transmit complying with Cat 6 specifications, jacks, patch cables, patch panels, cross-connects, and cabling must all meet Cat 6 standards. For example, if connectors in use comply with Cat 5e but not Cat 6 specs, then the Cat 6 cable can’t operate at 1 Gbps. The Changing Face of Network Strategy Scott Murphy June 19, 2019 Applications are changing the face of the network. Is your infrastructure ready? Cat 6A uses 16- to 20-gauge wires. Thicker wire translates onto higher PoE. Cat 6A cable is considerably thicker then Cat 6, which in turn is thicker than Cat 5. Cabling space may limit the number of cables that can be run in a conduit. Cat 6A supports 10 Gbps for the full distance of Ethernet (328 feet). Cat 6A also reduces the crosstalk among the wire pairs, which reduces the cable delay. You’ll have to verify if the Cat 6A cable can support PoE standard 802.3bt with power delivery of 60 and 100 watts. Selecting Cat X CableThe 10-Gbps network on Cat 6 cables is limited to 164 feet, including patch cables. Beyond this distance, the speed is the same as Cat 5e or 1 Gbps. The Cat 6 cable primarily uses 23-gauge wires, and sometimes Cat 6 may have a plastic piece in the middle of the cable that splits the pairs apart, making the cable thicker. The purpose of this design it to limit crosstalk. Log in or register to post comments
