Throughout his career, Stéphane worked in the telecommunications industry; in R&D, product management, training and marketing. These ethernet cables are modern-day products designed to cable appropriate environments. Class I, class II, and category 8 cabling will be backward compatible with lower classes and categories of cabling. Category 8 cabling is fully backward compatible with Category 6A cabling, including RJ45 connectivity, and supports all Category 6A applications such as 10GBASE-T for a distance of 100 meters. The physical connectors for Cat6 and Cat7 cables are still RJ45 plugs, but they're shielded and the standard calls for much less untwisting at the ends of the cable in the connectors than what is permissible for Cat5e. In fact, due to lower dc resistance and insertion loss, these cables may more efficiently support remote powering applications (e.g. After years of steady development, it looks like the bandwidth race is heating up, making Ethernet go farther and faster than any other time in its 40-year history. Its only limitation is distance, as it is limited to around 30m (or around 100ft) per run, where Cat7 can run up to about 100m in distance. It's when you try to do 10Gb/s or higher signaling on the cable that the Cat5e standard falls over. For example, a category 8 connector can be used in a class E A channel and class E A channel performance will be assured. Cons – Due to different connectors, they are not compatible with cat5e and cat 6 cables. Class I, class II, and category 8 cabling has a unique channel topology that is optimized for support of both 25GBASE‑T and 40GBASE‑T server to switch connections in the data center. Siemon TERA®) that are commercially available today, end-users should not see the arrival of class I and category 8 products significantly change the landscape of available high speed cabling options. Q:         What are the main characteristics of category 8 cabling and how will they affect data center infrastructure? Work with a Belden partner. 6A. Also, the components need to be designed to meet strict transmission performance specifications up to 2 GHz, which is four times the bandwidth of Category 6A and two times the bandwidth of Category 7A. Category 8 cabling is fully backward compatible with Category 6A cabling, including RJ45 connectivity, and supports all Category 6A applications such as 10GBASE-T for a distance of 100 meters. A Great-Quality Ethernet Cable with an … Is a Cat 8 Ethernet cable backward-compatible? Category 8 Cables: Cat8 cables or Category 8 ethernet cables have a vast difference from the previous versions because it can support a frequency of 2 GHz. ANSI/TIA‑568‑C.2‑1, which contains requirements for category 8 cabling constructed from category 8 components to support the 25GBASE‑T and 40GBASE-T applications, was approved for publication in June, 2016. Categories are backward compatible. An article on the popular Ghacks technology news blog by Martin Brinkmann, entitled, "Should you get a Cat6 or Cat7 Ethernet cable for your network? This cable can support a speed of 25 Gbps or sometimes 40 Gbps. Cat 6 vs. Cat 6a . 400 Gigabit Ethernet. Cat 6 supports 10 Gigabit Ethernet only up to 164 feet of cable … Q:         Will the arrival of category 8 cabling impact the adoption of category 7A cabling? With data centers looking for scalable copper cables that … Cat 8 Cable: The new 2GHz speed limit ... the cables remain backward compatible. A: The ANSI/TIA Category 8 solution utilizes an 8 position modular 8 connector (commonly known as RJ45) and was designed to be backward compatible with the existing 8 position modular connectors that are utilized in structured cabling from Category 5e through to Category 6A. This cabling may be installed in existing pathways and conduit; however, the existing infrastructure will need to be upgraded to support 25GBASE-T and 40GBASE-T. Q:         Will category 8 cabling require more power? … While Director in Technology and Applications, Stéphane focused on technology roadmap and ideation, networking applications and trends, and standards engagement. With the Category 8 cabling standard to be published later this year, it’s important to prepare for what this new standard will mean for data centers everywhere. Class I, class II, and category 8 cabling is characterized to 2 GHz and intended to support 30 meter cabling channels that contain no more than 2 connectors. These cables are expensive than the previous versions. Cat 7 cables are always shielded and use a modified GigaGate45 connector, which is backward compatible with RJ45 Ethernet ports. Director, Technology and Applications - Enterprise Networking. DbillionDa Cat8 Ethernet Cable. Aside from the wire twist requirements, in order for shielded connectors to wo… Cat8 cable is also backward compatible with its previous versions. To achieve that type of bandwidth using RJ45 connectivity is a significant accomplishment. CAT 8 PERFORMANCE for a 10GBASE-T, 25GBASE-T or a 40GBASE-T channel compliant network up to 30 meters; GHMT Cat 8 channel performance verified; Fully backwards compatible with Cat 5e (Cat5e), Cat 6 (Cat6), or Cat 6A (Cat6A) Ethernet networks with 10Gbps support up to 100 meters Sometimes that’s a purely economic issue (supply and demand or something like that), but in other cases it has to do with the cost of production. Q:         How is the performance of category 8 cabling improved over its predecessor versions? Sorry, the comment form is closed at this time. Recommendation for Cat.8.1 installations: Two measurements for formal acceptance should take place after installation, one for Cat. Interestingly, for every transmission parameter except return loss, ISO/IEC class FA channel and permanent link limits are more severe than those proposed specified for class I and category 8 up to 1 GHz. Since class II channel performance can be achieved with many of the category 7A connectors (e.g. Data center designers that can arrange their rack and cabinet layouts to support maximum 30‑meter channel connections at these locations today will be well-positioned to migrate to  25G/40GBASE-T when the technology becomes available. Power over Ethernet or “PoE”) and offer improved heat dissipation. They look pretty much the same; in fact, Cat 6 is backward compatible with Cat 4, so you can mix and match. It features a network speed of up to 2000MHz/40Gbps and a length of 25 feet. Other than that, the structure is covered with a shielded foiled twisted pair (SSTP).
