What is a Cat 8 Cable? CAT8 Ethernet Cable (CAT8 Explained)

What is a Cat 8 Cable? Cat 8 Ethernet Cable Review. With the development of fibre, many people assumed ethernet cables would soon become a thing of the past. Somehow, ethernet cables have managed to stay relevant in the world of technology. New developments arise every few years and they continue to push the envelope of traditional copper cables. So what is a Cat8 cable? The latest development is Cat8 Ethernet cable or category 8 ethernet cable. This cable is an advancement of its predecessor Cat7. As a general rule, a higher number represents newer technology that can support higher data rates. In addition, other differences can be cost, bandwidth, and shielding. Difference between Ethernet categories Cat5e and Cat6 cables Cat5e cables operate at 100MHz and transfer data at speeds of up to 1000Mbps. Cat6 Cables operate at 250MHz with speeds of up to 1Gbps. Cat6a cables will then take you on to 10 gigabit speeds Cat7 Cables Category 7 cables perform at superior speeds in comparison to the previous cables. Cat 7 works at 600Mhz and can get up to 10Gbps. This is a simplification, and these numbers are based on specific tests. There are variations on each cable and some arrangements that can boost or decrease the overall performance. Cat8 Cables Cat8 cables are far superior, they supersede all previous categories by a large margin. The cable reaches speeds of 25Gbps (cat8.1) to 40Bbps (cat8.2). Rated to a frequency of 2GHz, the cable can reach an outstanding 2 billion signals (transfers) per second. The high speed means all cables lengths are up to 30M using a 2-connector channel made up of a high density shielded cable. In comparison to Cat5 data transfers, Cat 8 is 250 to 400 times faster. Cabling Cost Differences Much alike most things, higher performance costs more. At times this is purely an economic issue, but in other scenarios it’s to do with the cost of production. This certainly applies when it comes to ethernet cables. Generally, it comes down to shielding and twists. Higher frequencies require more twists in the cable pairs and the process is more expensive. Additionally, it becomes more difficult to shield higher frequencies from interference and crosstalk. As you go up the scale the cost of raw materials for shielding becomes more expensive. Bandwidth explained The frequency of a cable determines how many 1s and 0s can be sent across the cable in a second. For instance, a basic Cat5 cable sends 100 million signals a second (100Mhz). Cat8 on the other hand uses an unprecedented 2 billion (2GHz) signals per second. The cable density and quality of shielding on a Cat8 cable are on a whole different scale. This becomes obvious when you take into consideration that Cat8 is rated for data transfers 250 to 400 times faster than Cat5. CAT8 Ethernet cable Advantages Compared to OM3 Multimode Optical Fibre • Cheaper alternative for channels less than 30M • Backwards compatible with Cat6 & Cat6a • Auto-negotiation supported • Mixed data rates on the same switch are enabled CAT8 Ethernet cable Advantages Compared to Twin-Axial Copper • Supports connections with same or adjacent cabinets • Backwards compatibility with RJ45 equipment • Auto-negotiation supported • Cheaper alternative for direct attached copper applications of 5m or less • Mixed data rates on the same switch are enabled • FOR MORE Q&As PLEASE VISIT OUR KNOWLEDGE CENTRE https://www.nmcabling.co.uk/knowledge... • Subscribe For More Video Tips On Data Cabling https://www.youtube.com/c/nmcablingco... • If You Enjoy These Videos Please Subscribe And "Like" ✔️ Have A Question About Data Cabling?
