is cat 8 the best ethernet cable

Cat8 is the fastest Ethernet cable yet. 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.

These prominent voices are available through podcasts, books, research, talks, and Twitter conversations, and small business IT professionals should be paying attention to them immediately.

Using Ethernet cables is an easy method to increase data transfer speeds. This is mainly the reason that the global Ethernet cable market is anticipated to surpass $30 billion by 2029 as companies continue to enhance their networking solutions to enable high-speed transfers.

But choosing between Ethernet cable options is complex, and making the right selection starts with understanding the distinctions between the latest categories of cabling: CAT 6, CAT 7 and CAT 8.

Practical Applications for Cat8 Cable

Data centers and server rooms are the ideal places for CAT8 cable. Additionally, CAT8 cable can connect to the majority of common network equipment because it has RJ45 connectors, upgrading your network without requiring a complete overhaul of the equipment.

Additionally excellent for networks undergoing transition to handle increased data loads is CAT8 Ethernet cable. If your company plans to grow and needs to upgrade from 10G, the most economical way to upgrade from a CAT6 or CAT7 network is to use optical fiber rather than CAT8.

You must determine whether upgrading to CAT8 cable is actually beneficial for your network as the cost of the connection decreases. In most cases, CAT8 cable provides more bandwidth than necessary for home and business networks.

Differences Between Ethernet Copper Cable Categories

Copper cable is classified by category designations that denote the:

  • Standard Bandwidth (MHz)
  • Data Rate (Megabits per second)
  • Shielding

Higher category numbers have higher data rates. The lowest data rate is offered by CAT3, and the highest data rate is offered by CAT8.

Standard specifications for a CAT8 Ethernet cable:

  • Connectors: RJ45/RJ45
  • Bandwidth: up to 2GHz
  • 4 Pair Braid Shield / Shielded Foilled Twisted Pair (S/FTP)
  • Max Data Rate: 40 Gbps
  • AWG: 22-24 AWG

These performance figures are remarkable, particularly when contrasted with other copper Ethernet cables.


Is Cat 8 cable overkill?

Cat8 Ethernet cables are designed to support extremely high data transfer speeds, up to 40Gbps. While they may provide a future-proof solution for gaming, they are generally considered overkill for most gaming setups.

Do Cat8 Ethernet cables make a difference?

The key distinction is that CAT 8 cabling has faster throughput over short distances — 40Gbps up to 30 meters and the standard CAT 6 rate of 10Gbps at up to 100 meters. This evolution from CAT 6 also has a bandwidth of 2000 megahertz, twice that of CAT 7.

Will Cat8 improve internet speed?

Cat8 data transfer speeds up to 40Gbps, which is quicker than Cat7 and is 4x faster than the predecessor, Cat6a.

Does Cat 9 cable exist?

Category 9 cables do not exist as an officially recognized standard. The Ethernet cable standards are defined by the Telecommunications Industry Association (TIA) and the International Organization for Standardization (ISO). These organizations have not released any specifications or standards for Category 9 cables.
