CAT7 VS CAT8: Which is Better to use?

There are multiple types of ethernet cables available, but which one is most suitable for you? Let’s find out.  

When it comes to setting up a network, whether it's for a cozy home office or a bustling enterprise environment, the type of cabling you choose is like picking the foundation for your digital house. It can make the difference between a network that's speedier than a caffeinated cheetah or one that's more like a tortoise on a leisurely stroll. Enter the world of Ethernet cables, where CAT7 vs CAT8 is the hot topic of debate among tech enthusiasts. So, grab your favorite snack, sit back, and let's unravel the tangled web of these cable categories! 

Understanding the Basics: What's with the CATs?  

Before we leap into the nuances of CAT7 vs CAT8, let's brush up on the basics. CAT stands for "Category," and the numbers that follow denote different specifications and standards set by the Telecommunications Industry Association (TIA). These standards dictate the cable's performance, particularly in terms of data transmission speed and bandwidth.  Now, picture your Ethernet cable as a digital highway. The higher the category number, the more lanes (bandwidth) and higher speed limits (data transfer rates) you have. But it's not just about speed; it's about how far the cable can carry data at that speed, much like how a sports car's performance might differ in city traffic versus on an open highway. That’s where bulk cables come in. Cat 7 bulk cable and Cat 8 bulk cable allow you to achieve higher speed transmissions over longer distances.  

CAT7 cables: The Once-Crowned Champions 

CAT7 cables, also known as Class F cabling, once sat at the top of the Ethernet cable hierarchy. It boasted support for high-speed Ethernet communication up to 10 Gbps (gigabits per second) and a bandwidth of up to 600 MHz. That's like being able to download an entire HD movie in less than a minute, hypothetically speaking, if your internet plan and the rest of your network infrastructure can handle it.   

But here's the kicker: CAT7 cables are shielded marvelously, which means it's good at reducing signal attenuation (signal loss) and is less prone to interference and crosstalk from outside sources. This shielding makes it an excellent choice for environments with lots of potential interference, like heavy machinery or fluorescent lighting. About waterproofing, is Cat 7 waterproof? CAT7 cables themselves are not inherently waterproof. Most standard Ethernet cables, including CAT7, are designed for indoor use and do not have waterproofing. However, there is an outdoor-rated CAT 7 bulk cable that has additional shielding and waterproofing for exterior use. 

Cat7a is also a variant of Cat7 cables which can further increase productivity. So, what is the specification of Cat7a? 

  • Bandwidth: Up to 1000 MHz, double that of CAT7 cables
  • Data Rate: Supports 10 Gigabit Ethernet connections over a full 100 meters (about the height of the Statue of Liberty), and it's rated for transmission frequencies of up to 1000 MHz.  
  • Shielding: Each pair of wires is individually shielded (Screened/Foiled Twisted Pair, S/FTP), with an additional layer of shielding over the entire cable to prevent interference (Alien Crosstalk).  
  • Connectors: Typically terminated with GG45 (backward compatible with RJ45) or TERA connectors.  
  • Cable Length: Effective up to 100 meters (about the height of the Statue of Liberty). 
  • Applications: Suitable for data centers and telecommunications rooms where higher performance cable systems are needed.  
  • Construction: Thicker and more rigid than CAT 7 bulk cable, due to extensive shielding.

CAT8 cables: The New Kid on the Block 

Then there's CAT8 cables, the latest and greatest, boasting bragging rights with speeds up to 25 Gbps or even 40 Gbps and a whopping bandwidth of 2000 MHz. That's like upgrading from a fast jet to a hypersonic rocket in terms of data transmission. CAT8 bulk cable is designed with professional and enterprise environments in mind, where the network infrastructure demands the highest speed for tasks like server connections and data center switching. 

Plus, CAT8 cables are shielded to the nines, ensuring that they offer the best protection against interference. They're like the armored trucks of the Ethernet cable world, keeping your data secure and uninterrupted. 

The Showdown: CAT7 vs CAT8 

So, which one should you choose? Let's break it down: 

  • Speed and Performance 

If you're all about speed, CAT8 cables are the undisputed champions. With its higher data transfer rates, it's the Usain Bolt of Ethernet cables. However, the real-world speed you'll experience also depends on your network equipment and internet service provider. If they're not up to par with CAT8's capabilities, you won't see much difference compared to CAT7 bulk cable. 

  • Cable Length 

When it comes to CAT7 vs CAT8, both have their limitations. CAT7 cables can transmit at 10 Gbps for up to 100 meters, while CAT8 can deliver its highest speeds of 25-40 Gbps up to 30 meters. If you need longer runs without a drop in speed, CAT7 might be your buddy. For shorter, more speed-intensive runs, CAT8 is your go-to. 

  • Compatibility and Use Cases 

CAT7 cables come with a GG45 connector, which is backward compatible with standard RJ45 Ethernet ports. CAT8, on the other hand, uses 8P8C connectors, which are also backward compatible but are relatively new. If you're looking to future-proof your home network for next-gen internet speeds, CAT8 might be worth the investment. But for the average user, CAT7 is more than sufficient. 

  • Cost 

No surprise here, CAT8 is generally more expensive than CAT7 because it's a newer technology with higher specs. If budget is a concern, CAT7 can offer a middle ground with high performance at a lower cost. 

  • Durability and Installation 

Both types of cables are quite sturdy, but the stiffer and thicker CAT8 can be trickier to install, especially in tight spaces. If you're a DIY network wizard, CAT7 cables might give you less of a headache during setup.  

  • Gaming: Cat7 vs Cat8 cable 

In the realm of gaming, both CAT7 and CAT8 cables are more than capable of providing a smooth, lag-free experience, as they offer high-speed data transfer that far exceeds the requirements of online gaming. CAT7 is ample for most gamers, supporting up to 10 Gbps bandwidths, while CAT8, with up to 40 Gbps, is overkill for current gaming needs. The difference in performance is negligible, so CAT 7 cable for gaming is generally the more cost-effective choice for most setups. 

To Sum It Up 

So, in Cat7 vs Cat8, which Ethernet cable should you choose? It really comes down to your specific needs:  

CAT7 cables: High-speed, cost-effective, longer cable runs, and perfectly suitable for home and small office networks. 

CAT8 cables: Top-of-the-line speed, more expensive, ideal for professional and enterprise environments where cutting-edge performance is required. 

Remember, the best choice for your setup isn't necessarily the one with the highest specs on paper, but the one that aligns best with your network demands and budget considerations. 

And there you have it, friends!
