The cable consists of 4 screened pairs, drain wire and additional outer foil. It helps to alleviate the problems of NEXT and alien crosstalk. The sheath is a Low Smoke Zero Halogen (LSZH) material, as specified in many public buildings. It ahs a euroclass rating of Bca, making it the ideal choice when BS6701 compliance is a requirement Delivered on 500m Drums. That’s not to say that you can’t use Cat5e these days, though. There’s nothing wrong with using these wires; it would just help you get better connections if you were using a new model. This needs to be balanced against the goal to “future proof” the network. The wiring is a project to install, and the labor costs, when done by professionals, usually exceed the materials cost. But it's tempting to spend a little more in the hope that the network will outlast the peripherals. For those that want to take this route, Cat6 or Cat6a are good options.

Alongside its unique launch timeframe , Cat7 has some unique eccentricities where other categories of cable adhere to strict specifications for all parts of their design. Partly because of that, but also because more standard Ethernet cables are now readily available and can compete directly with Cat7 , it's not hugely popular, despite its impressive specifications (especially considering when it was released). But the magic of that higher number means that comparable cables of lower categories are occasionally mis-sold as Cat7 cables instead. In fact, if you come across a Cat7 cable from some other retailer, you’re almost certainly buying a Cat 6A cable.
So, that covers the North American ANSI/TIA side. How does Cat7 compare? Cat7 is defined by ISO/IEC 11801. GG45: The GG45 connector has four additional conductors that provide support for frequencies of up to 600 MHz. Written by Don Schultz, trueCABLE Technical Manager, Fluke Networks Copper/Fiber CCTT, BICSI INST1, INSTC, INSTF Certified While it’s certainly true that very few typical home hardware setups will support anything like the sorts of data transfer speeds and bandwidths that Cat7(a) Ethernet cabling can, using the highest revision wire you can will still offer potential performance boosts in many basic router-to-device networking scenarios. As you might expect, Cat 7 is a superior gigabit ethernet cable on account of it being newer. However, it is also more expensive.
Where Cat7 cables sound great on paper -- especially considering when they were originally released – there are some reasons why the standard is not as useful or as viable as comparable cables like Cat6A. Cat7 can support 10 Gbps, but laboratory tests have successfully shown its ability to transmit up to 40 Gbps at 50 meters and even 100 Gbps at 15 meters. The cabling can support frequencies of up to 600 MHz. Connectors for Cat 7 Ethernet Cables The fact that Cat5e is UTP makes a massive difference to the quality and is one of the leading reasons it is such an inferior option to Cat6 or Cat7. So, what is Cat7? It's an Ethernet cable for sure, but you probably don’t need to worry about it. In fact, we’re almost certain you’d be better off with a Cat6A, or Cat 8 Ethernet cable instead. By the numbers It may cost you less than more modern cabling, but you need to be prepared for when you get slower connections with more crosstalk.
You might still see some standard Cat5e network cabling being used every now and again, but it’s not as popular as Cat6 and Cat6a cable. Even though it still gives your home a bandwidth that could be considered acceptable, it is several generations outdated. However, if you are one of the few who want or need a Cat7 Ethernet cable or three, then you need to be sure that what you're buying is Cat7. Don't be caught out by Cat6A masquerading as the older standard. Be sure you buy from a reputable cable trader like Cable Matters and if in doubt, get in touch with support to find out exactly what type of Ethernet cable you’re buying. Do You Need Cat7 in 2023? The lifespan of the two different cable types also differs. Cat6 has an average lifespan of about 10 years, whereas Cat7 cabling is going to last you around 15.
Cat 7 ethernet cables feature four individually shielded pairs as well as an overall cable shield to protect the signals from crosstalk and EMI. Cat7 cables are designed for use in Industrial Ethernet networks, designed to withstand the entire spectrum of environmental and mechanical hazards, from temperature extremes and sunlight to solvents, oils, chemicals and moisture. Cat 7 Ethernet Cable Support The Cat 7 cable is similar in physical makeup to the previous Cat6 cable. Both versions use the same twisted and sheathed four-pair cable design as each other, capable of delivering transmission frequencies (bandwidth) of up to 600 MHz, and therefore both support 10 Gbps Ethernet signals over distances of up to 100m. Category 7a cable was likely originally introduced as a future-proofing step for the anticipated wider uptake of a 40 Gbps Ethernet standard - however, in 2016 a new ratification meant that this responsibility was effectively handed over to Cat8 cables specified to 2000 MHz. As a result, cable Cat7a as a standalone revision isn’t officially supported by very much equipment to run at significantly faster speeds than Cat7 versions, although speed boosts may be possible in certain applications.The wires that are utilized in Cat 5e don’t even have any sort of foil covering, which is to say are UTP. UTP stands for unshielded twisted pairs and refers to wires that don’t utilized coatings to help eliminate crosstalk. If you’re already running Cat 6 or Cat 6A, it’s not necessary. What you have is more than fast enough and the standard shielding of both cable standards is perfect for home use. If you’re running older Cat 5 cables, however, you may want to upgrade to benefit from the improved performance and shielding of newer Ethernet cables. That said, whether you’re building a new network or upgrading an older one, leave Cat7 well enough alone. It’s a dead standard that isn’t going to see any further adoption and its benefits are easily matched and outweighed by competitor cables, like Cat 6A, or the latest and greatest, Cat8. NBASE-T is also a game changer. Now, 2.5GBASE-T and 5GBASE-T are realities for existing Cat5e and Cat6 (respectively) unshielded cable installations. These speeds will satisfy all but the most demanding home and small business users. See more about NBASE-T in Just What is NBASE-T? A note on both Cat7 and Cat8
Also, with virtually all consumer gear, such as routers, motherboards and Ethernet cards, max out at 1000 megabits or 1 Gbps. So for the time being, and likely years to come, the typical user will not be able to take advantage of the 10 Gbps and faster speeds of the Cat6a and higher cables. In terms of shielding both cables are roughly equal as standards. They both require shielded twisted pairs and an overall shielding over the cable itself, but Cat 8 comes in a wider range of shielded options. Some have splines, others add additional foil or braided shielding for the overall wire, and some have both. As Cat 9 and 10 will surely come along, it's worth wondering what the next generation of wired connectivity will look like. Many homes already get blazing internet speeds via Fiber to the Home (FTTH), but the current technology limits them to copper Ethernet cables to then connect to the router, access points and other networking accessories. The next step could be to extend fiber's reach to inside the home with the ability to carry thousands of times more data than copper wires can today. Although it's not recognized by the Telecommunications Industry Association (TIA), Category 7 cable debuted in 2010 and is aimed at data centers and server rooms where top speed counts. Each cable is double-shielded: around each pair of wires and an overall shield around the entire bundle of wires. This extra isolation is needed because the 600MHz frequency used can push a maximum of 10Gbps over 330 feet. More recently, the introduction of Cat 7A cable increases the speed to 1GHz and throughput to 40Gbps, but tops out at 165 feet. Cat 8 Cable: The new 2GHz speed limitNo doubt while shopping for Ethernet cable you have seen Cat7 cabling for sale. What exactly is this type of cable and should you use it? Let’s see if we can let the “Cat” out of the proverbial bag! The Cat you don’t need or even want... Taking a look at the specifications between Cat7 and Cat6A we have identical performance for all intents and purposes, regardless of the specification difference of 100 MHz, which means they will both run at the maximum 10 Gigabit speed. There is no reason to opt for Cat7 when bulk Cat6A cable is readily found and typically for less money. Cat6A will also be far easier to work with and terminate. Reality sets in…. As for cost, Cat 8 Ethernet cables are typically a little more expensive, but considering you get the ratified and official standard and supported features, as well as more impressive rated performance, there really is no competition: Cat8 cables are better. You probably don't need Cat7. Use Cat6A or Cat8 instead he will not allow me to plug anything into his router.… The distance between his router inside the office upward to the roof is about 15 feet There is also a plan to increase the speeds of Cat5e to 5 Gbps over the existing cables, known as the IEEE P802.3bz standard, which also works on Cat6 cabling.
