Network Cable Comparison
Cat6 vs. Cat6A: Which Network Cable Is Better for Your Glendale Business?
Cat6 and Cat6A look almost the same at the wall jack, but they differ in speed over distance, heat handling for PoE, size, and cost. Here’s how to decide which one belongs in your Glendale office, clinic, studio, or storefront.
What Cat6 and Cat6A Actually Are
Cat6 and Cat6A are both categories of twisted-pair copper Ethernet cable defined by the TIA-568 standard. Each has four twisted pairs, uses the same RJ45 connector, and works with the same switches, computers, and access points. The difference is in how the cable is built and how much data it can carry reliably over distance.
Cat6 is rated to 250 MHz. It carries 1 Gbps across the full 100 m channel and 10 Gbps over shorter runs, typically up to about 55 m depending on how tightly cables are bundled. Cat6A, the “augmented” version, is rated to 500 MHz and carries 10 Gbps across the full 100 m. It’s also built to resist alien crosstalk, the interference between neighboring cables in a bundle, which is what limits Cat6 at 10 Gbps.
At Network Cabling Company Glendale, we install both, and most of our commercial projects use a mix. The right answer depends on what each drop connects to and how long you plan to keep the cable in the wall.
| Specification | Cat6 | Cat6A |
|---|---|---|
| Bandwidth | 250 MHz | 500 MHz |
| 1 Gbps distance | 100 m | 100 m |
| 2.5 and 5 Gbps (NBASE-T) | Typically 100 m | 100 m |
| 10 Gbps distance | About 37–55 m, depending on bundling | 100 m |
| Alien crosstalk resistance | Not specified | Specified and tested |
| PoE support | PoE, PoE+, and PoE++ (IEEE 802.3bt) | PoE, PoE+, and PoE++, with better heat handling in large bundles |
| Typical outside diameter | About 5.5–6.5 mm | About 7–8.5 mm |
| Relative cost per drop | Lower | Typically 25–50% higher |
When Cat6 Is the Right Choice
For a large share of everyday connections, Cat6 is all you need. Most desktop computers, laptops on docks, VoIP phones, printers, and POS terminals connect at 1 Gbps, which Cat6 delivers across the full 100 m with room to spare. It also handles the 2.5 and 5 Gbps speeds that many newer devices and access points use, over typical office run lengths.
Cat6 is smaller and more flexible than Cat6A, so it fits more easily into crowded ceilings, older conduit, and tight wall cavities. That matters in older Glendale buildings along Central Avenue and San Fernando Road, where pathway space is often limited.
Cat6 is usually enough for
- Standard desks and workstations at 1 Gbps.
- VoIP phones and conference room phones.
- Printers, copiers, and label printers.
- POS terminals and payment devices.
- Short runs where 10 Gbps is needed under about 55 m.
- Budget-sensitive projects with short planned occupancy.
When Cat6A Is Worth It
Cat6A earns its extra cost wherever speed, distance, or power demands are high, or where you expect to keep the cable through several equipment upgrades.
Wi-Fi access points. Wi-Fi 6E and Wi-Fi 7 access points increasingly ship with multi-gigabit uplinks, and higher-end models support 10 Gbps. Industry guidance for wireless cabling recommends Cat6A to each access point so the cable won’t be the bottleneck when you upgrade. In a Brand Boulevard office tower with dense Wi-Fi needs, that’s usually the deciding factor.
High-power PoE. PoE++ can deliver up to 90 W at the switch to PTZ cameras, displays, lighting, and access points. Carrying that much power through large bundles creates heat, and Cat6A’s larger construction dissipates it better, which helps protect performance over time.
10 Gbps workstations. Glendale’s animation, post-production, and design firms regularly move large media files between workstations and shared storage. Cat6A delivers 10 Gbps at full distance, so an edit bay at the far end of a floor gets the same speed as one next to the rack.
Choose Cat6A for
- Wi-Fi 6E and Wi-Fi 7 access points.
- PTZ and multi-sensor IP cameras on PoE++.
- Edit bays, render stations, and CAD workstations.
- Medical imaging workstations and connected equipment.
- Runs longer than about 55 m that need 10 Gbps.
- Long-term leases or owned buildings where cable will stay 10+ years.
Installation Differences That Affect Your Project
Cat6A performs as rated only when it’s installed correctly, and it’s less forgiving than Cat6. These are the practical differences that show up on a Glendale job site.
| Consideration | Cat6 | Cat6A | Why it matters |
|---|---|---|---|
| Pathway fill | More cables per J-hook, tray, or conduit | Fewer cables fit in the same space | Crowded high-rise ceilings may need added pathway. |
| Bend radius | Smaller minimum bend | Larger minimum bend | Tight turns can degrade performance. |
| Termination | Standard jacks and panels | Larger, Cat6A-rated jacks and panels | Every component must match the category. |
| Shielded options | Usually unshielded (UTP) | UTP or shielded (F/UTP) | Shielded cable must be bonded and grounded correctly. |
| Weight and handling | Lighter, easier to pull | Heavier, slower to pull | Adds labor time on large projects. |
| Testing | Certified to Cat6 | Certified to Cat6A, often with alien crosstalk checks | Test reports prove the plant meets its rating. |
How Much More Does Cat6A Cost?
Cat6A typically costs about 25 to 50 percent more per drop than Cat6. The cable and connectors are more expensive, and the larger, stiffer cable takes longer to pull, dress, and terminate. In the Glendale area, a typical commercial Cat6 drop runs about $150 to $300, while a Cat6A drop runs about $225 to $450.
That gap looks significant on a quote, but labor, not materials, is the biggest part of any cabling job, and most of that labor is the same for both categories. Replacing Cat6 with Cat6A after the ceilings close costs far more than installing Cat6A the first time.

| Warehouse or light industrial | Cat6 | Cat6A | Long runs to high ceilings often favor Cat6A, with fiber where runs exceed 100 m. |
How to Decide for Your Building
- List what each drop connects to. Desks, phones, access points, cameras, and workstations each have different speed and power needs.
- Measure the longest runs. If a drop needs 10 Gbps beyond about 55 m, it needs Cat6A or fiber.
- Check your PoE plans. High-power cameras, displays, and access points in large bundles are a strong case for Cat6A.
- Consider how long you’ll stay. On a long lease or an owned building, Cat6A usually pays for itself over the life of the cable.
- Walk the pathways. Confirm there’s room for Cat6A’s larger size in ceilings, conduit, and wall cavities before committing.
- Insist on certification. Whichever category you choose, require test reports on every run, labeling, and as-built documentation.
Choosing the right category is only half of the job. The cable performs to its rating only when it’s planned, supported, terminated, and tested as part of a complete system, which is why the installation matters as much as the cable.

Frequently Asked Questions
Can I mix Cat6 and Cat6A in the same building?
Yes. Many Glendale businesses use Cat6 for desks and phones and Cat6A for access points, cameras, and high-demand workstations. Each individual run should use components of one category from end to end.
Will Cat6A make my internet faster?
Not by itself. Your internet speed is set by your carrier service. Cat6A improves speed and reliability inside your building, especially for 10 Gbps connections, access points, and high-power PoE devices.
Is Cat6 still a good choice in 2026?
Yes, for 1 Gbps devices such as most desks, phones, printers, and POS terminals. It also supports 2.5 and 5 Gbps over typical run lengths. For access points and anything that needs 10 Gbps at full distance, Cat6A is the better long-term choice.
Do my switches need to be upgraded to use Cat6A?
No. Cat6A works with existing 1 Gbps and multi-gigabit switches using the same RJ45 connectors. You get the extra capacity whenever you upgrade to 10 Gbps equipment.
Should I choose shielded or unshielded Cat6A?
Unshielded (UTP) Cat6A works well in most offices. Shielded Cat6A can help near heavy electrical equipment or in high-interference areas, but it must be bonded and grounded correctly to work as intended.
Is Cat7 or Cat8 better than Cat6A?
For typical business networks, no. Cat7 is not a TIA-recognized category for RJ45 installations, and Cat8 is designed for very short data center links of up to 30 m. Cat6A remains the standard choice for 10 Gbps horizontal cabling.
