Transitioning to a new ethernet cable standard like Cat8 leaves many wondering – what are the real differences compared to the Cat5e and Cat6 cables we know? Will upgrading improve my network? Is it worth the cost for my needs?
This guide will examine those questions in plain language, cutting through specifications to reveal what Cat8 delivers vs typical Cat6, and when deploying next-gen cabling future-proofs your infrastructure.
Understanding Ethernet Cable Categories
The relied-upon ethernet cables shuttling data between our devices come in different types, or categories. Each has its own set of capabilities based on specifications published by the IEEE industry group over the last 30+ years:
- Cat 3 – 10 Mbps networks circa 1990
- Cat 5 – 100 Mbps networks circa 1995
- Cat 5e – Gigabit ethernet, 1000 Mbps circa 1999
- Cat 6 – 10 Gigabit ethernet, 10 Gbps circa 2002
- Cat 6a – 10Gbps over longer distances circa 2008
- Cat 7 – Up to 10Gbps, shielded cable circa 2011
- Cat 8 – 25 and 40 Gbps networks circa 2016
Higher categories like Cat7 and Cat8 deliver faster maximum data transfer rates and increased bandwidth potential versus earlier iterations. They push boundaries to handle exponentially growing demands in the era of 4K video, cloud computing and IoT devices.
To simplify purchasing decisions, we‘ll focus this guide on explaining the nitty-gritty differences between the most widely used Cat6 cables and newer Cat8 – now readily available as enterprise networks migrate to 25, 40 or 100GbE connections.
Cat8 vs. Cat6 Ethernet Cables Compared
How exactly does Cat8 stack up to ubiquitous Cat6 ethernet cabling? Here are the key contrasts across crucial specifications for real-world networking performance:
| Specification | Cat 6 | Cat 8 |
|---|---|---|
| Max Speed | 10 Gbps | |
| Max Bandwidth | 500 MHz | 2,000 MHz |
| Max Length | 100 meters | |
| Shielding | Unshielded | Shielded |
| Min Bend Radius | 4x Cable Diameter | 8x Cable Diameter |
| Transmission Range | 1Gbps – 10Gbps | 25Gbps – 40Gbps |
With 4x higher bandwidth (2000 MHz), Cat8 supports up to 40 Gigabit per second (Gbps) speeds vs Cat6 at 10Gbps – crucial for transferring massive data sets. However, Cat8 cables only span ~30 meter distances vs. 100 meter Cat6 runs before degrading signal requires regeneration.
In short, Cat8 rapidly transports more data with less jitter/noise, but doesn‘t travel as far and costs more than battle-tested Cat6.
When to Adopt Faster Cat8 Cables?
Cat8 shines in high-performance computing networks transmitting enormous data loads that would choke older cable categories. For example:
- Scientific Research – transfer huge genome data sets from gene sequencers
- Finance – low-latency algorithmic trading at securities exchanges
- Media Production – 8K video editing requiring massive bandwidth
- Smart Cities – interconnect autonomous vehicles and HD security cameras
Conversely, Cat6 provides more than enough headroom for conventional business/home needs – like email, web browsing, mobile device syncing etc. Upgrading to Cat8 sees zero benefit for these simpler use cases limited to 1GbE speeds anyway. Some examples:
- Small office networks
- Connecting lobby WiFi access points
- POS register and inventory systems
- Network-attached printers
Before rewiring your entire building, analyze current network utilization along with storage and application demands to predict bandwidth needs 3-5+ years out.
Cost and Compatibility Considerations
While Cat8 delivers next-gen performance, more factors come into play when assessing upgrade options:
Pricing
Unsurprisingly as the newest standard, Cat8 carries steeper price tags. Expect to spend 20-40% more compared to equivalent Cat6 cable lengths:
- Cat6 25‘-50‘ spool: $15 – $60
- Cat8 20‘-50‘ spool: $25 – $150
Availability
The Cat8 landscape continues maturing – major retailers like BestBuy and MicroCenter now stock various options. But niche lengths/colors still remain harder to source than ubiquitous Cat6.
Hardware Compatibility
All connected equipment – routers, network cards, switches, modems etc. – must also support 25+GbE transmission to fully leverage Cat8 capabilities. Piecemeal upgrades cause bottlenecks, so budget for wider infrastructure enhancements if pursuing leap to Cat8.
Key Takeaways Between Cat8 and Cat6 Cables
-
For hyper fast networks, Cat8 is the superior future-proof choice – supporting up to 4x higher data speeds and bandwidth than common Cat6 ethernet cable variants.
-
With 10Gbps throughput, Cat6 still reliably handles typical office and home workloads – faster expensive Cat8 upgrades provide zero concrete improvements for average users…for now.
-
When predicting future network needs, analyzing expected bandwidth demand growth patterns across users/devices/applications is key before committing to next-gen cable installations.
Now that we‘ve covered the Crucial differences between Cat8 and Cat6, let‘s move onto some recommendations!
Good, Better & Best: Ethernet Cable Recommendations
Here are top-rated Cat6 and Cat8 products across budget and prosumer categories – whether optimizing day-to-day networks or maxing out bleeding edge infrastructure.
| Use Case | Good 👍 | Better 😃 | Best 🤩 |
|---|---|---|---|
| Budget Home/Office | Monoprice Cat6a – $15 | Amazon Basics RJ45 Cat6 Patch – $23 | N/A |
| Performance Networks | Tripp Lite Cat6 Snagless – $57 | Belden Cat6A Bonded Pair – $95 | Siemon Cat8 Shielded – $180 |
