Cat7 Ethernet Cable: Specs, Features, Pros & Cons
Most cable sold as "Cat 7" cannot claim the class printed on it, although Category 7 itself is a real ISO standard. The class is tested to a high bandwidth, with each pair wrapped in its own foil and a braid around the whole cable. The American standards body, TIA, never recognized it, so there is no Category 7 in the specification most US installers work to.
The standard was written around connector types that almost nothing uses, and the ordinary RJ45 on every switch, laptop and wall plate is not one of them. A cabling channel is only certified to a class when the connectors match the cable, so a "Cat 7" patch lead terminated in RJ45 plugs, which is what is sold online, does not form a compliant Class F channel. It is a well-built shielded cable wearing a label it cannot technically justify.
None of that makes the cable useless, because the construction is good, the shielding helps in electrically noisy environments, and it will run ten gigabit and the full power-over-Ethernet range without trouble.
The higher number suggests something faster than Category 6a, and it is not. Both are ten gigabit grades over the same hundred-meter channel, and the RJ45-terminated version cannot claim the standard printed on its jacket.
This grade makes sense only where the proper connectors are being used, which in practice means specialized shielded installations, mostly in Europe, built with matching outlets and patch cords.

Where the Cat7 Ethernet Cable trails the median

How this VS Score was computed
Score 73: each known spec is measured against the median of all ethernet cables (8 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 75% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

| 10 Gigabit Ethernet | Yes | 63% of the class have it | 2 | +100.0 |

| Native RJ45 connector | No | 75% of the class have it | 2 | −96.0 |

| Multi-gig (2.5G / 5G) | Yes | 75% of the class have it | 1.5 | +75.0 |
| Typical shielding | S/FTP (braid over foiled pairs) | U/UTP (unshielded) | 1.5 | +75.0 |
| Shielded construction | Yes | 38% of the class have it | 1 | +50.0 |

Not scored: Gigabit Ethernet (standard for the class (88% have it)); 25G / 40G Ethernet (not applicable: only 13% of this class have it); Alien crosstalk limits (unknown: not scored); Conductor material (unknown: not scored); Snagless boots (unknown: not scored); PoE++ (Type 4, 90 W) (standard for the class (88% have it)); Backward compatibility (standard for the class (100% have it)).
Editor’s note
Category 7 is the most misunderstood cable on the market, and the confusion is worth untangling before you buy it. It is a real standard, but an ISO one: Class F in ISO/IEC 11801, published in 2002, tested to 600 MHz with every pair individually foiled inside an overall braid. TIA never recognized it. There is no ANSI/TIA category 7.
The catch is the connector. Class F was written around GG45 and TERA connectors, not the ordinary RJ45 that every switch and laptop on earth uses. A channel only certifies to Class F if the connectors are Class F too. Almost every cable sold online as "Cat 7" terminates in a standard RJ45, which means the finished link certifies to Class EA, the Cat 6a level, regardless of what the cable itself could do. You are buying Cat 6a performance in a heavier jacket.
That is not to say the cable is bad. The individually shielded pairs help in electrically hostile places, running alongside mains cable or through plant rooms, and the shielding lowers emissions in environments where that is regulated. But shielded cable is only as good as its bonding: the screen has to be continuous and grounded at both ends, and a shielded cable terminated into an unshielded socket is worse than plain unshielded cable, because the screen becomes an antenna.
Equipment makers standardized on RJ45 for 10 Gigabit, TIA revised Category 6 into 6a to suit, and Cat 7 was left as a European specialty plus a marketing label on consumer patch cords. If you want shielding, buy shielded Cat 6a and connectors to match.

The bottom line
The Cat7 Ethernet Cable earns a VS Score of 73, above the median of the 8 ethernet cables it is measured against (a score of 50 is level with that median).
- Who it’s for
- Shielded ISO installations in electrically noisy environments, terminated properly in GG45 or TERA connectors.
- Who should look elsewhere
- Any ordinary network. Terminated in RJ45, as retail cords are, it certifies no higher than Cat 6a.
- The trade-off that matters
- Better shielding and bandwidth on paper, undone in practice by a connector ecosystem almost nobody uses.
- The main alternative
- Cat6a Ethernet Cable: the same ten gigabit on connectors every device already has
