Cat8 Ethernet Cable Offers Faster Speeds and Better Performance

From the cloud to the edge, IT networks need to move more data than ever before, and they need to move it quickly. The right infrastructure cabling will facilitate maximum speed and performance. IT managers who are designing or upgrading a network have a number of cable options to navigate, including where and when to use Cat8 cable.

Cat8 Ethernet Cable Basics

Category 8, or just Cat8, is the latest standard in copper Ethernet cable to become available. It offers a significant leap in performance over the earlier Cat6a standard. Its data transfer speed of up to 40 Gbps is four times faster than Cat6a, while its support of bandwidth up to 2 GHz (four times more than standard Cat6a bandwidth) reduces latency for superior signal quality.

Cable Type Frequency Max. Speed
Cat5/Cat5e 100 MHz 100 Mbps
Cat6 250 Mhz 1 Gbps
Cat6a 500 Mhz 10 Gbps
Cat7 600 Mhz 10 Gbps
Cat8 2000 Mhz 40 Gbps

What is Cat8 Cable Used For?

Cat8 Ethernet cable is ideal for data centers and server rooms, where 25GBase‑T and 40GBase‑T networks are common. Its RJ45 ends will connect standard network equipment like servers, switches, routers, modems, hubs, adapters and patch panels, allowing for 25G or 40G network upgrades that do not require a complete equipment overhaul.

Shielded foiled twisted pair (S/FTP) construction includes shielding around each pair of wires within the cable to reduce near-end crosstalk (NEXT) and braiding around the group of pairs to minimize EMI/RFI line noise in crowded network installations.

Should I Use Cat8 in my Home Network?

You can use Cat8 in a home network but it's really designed for high-speed switch to switch communication in a data center. Plus, the heavier gauge shielded Cat8 cable is quite rigid and difficult to install in tight spaces. A better, more cost-effective choice for a "future-proofed" home network would be Cat6 or Cat6a cable.

PoE on Cat8

Cat8 cable supports Power over Ethernet (PoE) technology for delivering power and data over a single cable. By eliminating or reducing the need for power cords, Cat8 cable can save space in crowded server rooms and simplify edge computing installations. With a maximum range of 98 ft. (30 m), Cat8 cable can reach PoE devices like security cameras and wireless access points when they are not conveniently close to an AC power source.

Tripp Lite Cat8 Cables

Tripp Lite offers Cat8 cables with lengths ranging from 3 ft. (0.9 m) to 25 ft. (7.6 m). All models support PoE and offer convenient snagless RJ45 connectors, integral strain relief and a lifetime warranty.

Tripp Lite offers six new Cat8 cables.
