Cat6a Bulk Cable: The 10G Baseline
Quick answer / TL;DR: Short answer: choose Cat6a bulk cable when the link must carry 10G to 100 m. Expect a diameter around 7 to 8 mm and a bend radius that needs 25 mm or more. Decide shielded or unshielded before ordering, because the connector and panel must match the choice.
One category, three axes: shielding, conductor and jacket create the SKU.Cat6a is specified to 500 MHz and supports 10GBASE-T to the full 100 m channel. That is its reason to exist over Cat6.
The cost is a larger, stiffer cable that needs more conduit space and wider bends.
Why Cat6a
| Category | Bandwidth | 10G distance |
|---|
| Cat5e | 100 MHz | Not supported |
| Cat6 | 250 MHz | Up to 55 m |
| Cat6a | 500 MHz | 100 m |
| Cat8 | 2000 MHz | 30 m |
The 55 m figure for Cat6 is the reason Cat6a exists in horizontal cabling: most real runs exceed it.
Installation Consequences
- Larger diameter reduces conduit fill capacity
- Bend radius needs more space at corners
- Shielded versions need bonding at the panel
- Stiffer cable is harder to pull in bundles
- Termination takes longer than Cat5e
The bonding point is the one that fails inspections: a shielded cable connected to an unbonded panel behaves worse than unshielded.
Real-World Applications
A new office build expecting 10G to the desk uses Cat6a throughout, which avoids a future re-cable. A home with 30 m runs and 1G service does not need it, and Cat6 is cheaper and easier to install.

Practical Notes
Buy the connectors and panel from the same performance class as the cable. Mixing classes caps the link at the weakest part.

Frequently Asked Questions
Does Cat6a do 10G to 100 m?
Yes, within the 100 m channel.
Is it harder to install?
Yes. Larger diameter and stiffer jacket.
Shielded or unshielded?
Decide first; the panel must match.
