so I want to spend a little extra money to get something that will give me the very best signal possible on the other end of this 300 foot cable in my motorhome and sturdy 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.

You never know what this cable will be exposed to with regards to perhaps people maybe walking on it and of course rain and sun Additionally, many people first bought into Ethernet connectivity fairly early on in the home hub era (around the Cat5 cable revision or earlier), and naturally look to the latest versions when needing to replace or upgrade older cables. Those planning to wire a smart home today, for example, might typically gravitate towards Cat7 and Cat7a as a future-proofing measure, anticipating the continued acceleration of home hardware and connection speeds over the coming years. 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 feetCategory 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. 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 As you might expect, Cat 7 is a superior gigabit ethernet cable on account of it being newer. However, it is also more expensive. 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…. 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.
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. 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 One additional strength of Cat7 cable over Cat6 is that the newer variant is better shielded against crosstalk and EMI, having been double-shielded (both individual wire twists and the cable as a whole) to meet more stringent specifications in this regard. This is the only out-of-the-box physical difference between most Cat6 and Cat7 cables - while double-shielded designs are now available with Cat6 and even earlier revisions of Ethernet grade wire, it’s part of the core design for Cat7 versions.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. 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 limit 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?
ISDN, Ethernet 10 Base-T, Fast Ethernet 100 Base-T, Gigabit Ethernet 1000 Base-T, 10G Base-T. (IEEE 802.3). GG45: The GG45 connector has four additional conductors that provide support for frequencies of up to 600 MHz. But which cable is the best to use? Just like there is no best computer or best router for everyone, it comes down to a few variables.Unless your network equipment is up to the task, you are likely using 1 Gigabit Ethernet technology like 99% of the world. 10 Gigabit equipment is extremely expensive. While it is becoming more available, it is likely only found in medium and large businesses that have the need for very high speed. Cat7 cable will not make your existing network equipment or internet any faster. You will simply waste money. For the average home and small business user, purchasing anything higher than Cat6 is of no benefit either. This all said, if your network is designed to run 10 Gigabit speed, and you need this speed past 110 feet (165 feet depending on conditions) then indeed Cat6A is the way to go. For help with deciding what network technology best matches the cable to use, take a look at The Need for Speed. Category 6 cable appeared at the start of the 21st century and remains popular with home networkers. Category 6 runs at up to 250MHz and sometimes used shielding around the bundle of data-carrying wires to reduce interference. Capable of moving up to 1Gbps over 330 feet, or 10Gbps for about half that, Cat 6A upgraded the spec to 500MHz for 330 feet of 1Gbps throughput. (See our primer on Gigabit-speed internet to learn why that 1Gbps threshold is so important.) Those other categories of cable were part of the standard development of Ethernet cables. They improved incrementally generation upon generation and were released in a fairly uniform manner over the years, but Cat 7 was an attempt to leapfrog ahead of that, delivering much greater performance potential years ahead of comparable Ethernet cable designs. Fast-forward to the early 1990s and Category 3 cable, which is often called the first modern networking cable, boosted the cable's frequency to 16MHz and Ethernet performance to 10Mbps. By contrast, Category 4 cable pushed this to 20Mhz and roughly 16Mbps but it was used for Token Ring – rather than Ethernet – networks.
Every so often you will see a product that promises everything and more. It is marketed as a way to increase your speed, overcome all interference, and what you should buy for the future. Sadly, this is how Cat7 is positioned to take advantage of the uninformed. The number is higher, so it must be better right? Not necessarily. The truth of the matter is Cat7 is not even ANSI/TIA recognized in North America. Cat7 is defined by an international specification created by ISO/IEC. Cat6a is, for the most part, not that much different from Cat6, but there are some differences worth noting. The cost is about 20-35% higher than Cat6, but the maximum cable length is 100 meters across all systems and conditions for Gigabit Ethernet; it's theoretical top speed is 10 Gbps over 100 meters (330 feet) of cable. The transmission bandwidth is also doubled, from 250 to 500 MHz, and Cat6a cables are often shielded, which makes them ideal for industrial use. Cat7 and beyond 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.No 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...
