Thats pretty thin. Should be 22 or 23 for quality Cat7.
If you need a long, flat ethernet cable this should be an acceptable option. If you're actually seeking a good Cat7 option you'd do better with something else.
Good luck!

no noticeable difference between my solid copper cat 6 when using for IP cameras

This cable would work fine for a POE camera.
There's not even a point to using anything above Cat6a as far as copper cabling goes.
Since he'd already made the cables of varying lengths, I figured might as well run a test. How long can mis-wired Ethernet cables convey a signal? The shorter ones worked fine. Around 25 ft was when we started having problems sustaining Gigabit speeds (they'd occasionally fall back to 100 Mbps). And the 50+ ft cable was incapable of Gigabit, only 100 Mbps. For comparison, properly twisted pairs are supposed to be capable of Gigabit up to 100 meters (330 ft).
Granted, this will depend heavily on the electrical noise where your cables lie. But if Gigabit speeds are necessary, I'd be reluctant to use flat Ethernet cables (which lack twisted pairs) if they're longer than about 20 ft.
(And if you're curious, the T-568 standard was made to maintain backwards compatibility with 4-conductor RJ11 telephone lines. Where the inner pair are phone line 1, and the outer pair are phone line 2. In a pinch, you can use adapters to plug a landline telephone jack into an Ethernet cable, and use the Ethernet cable as a telephone line. That's the sole reason why you can't terminate Ethernet cables color/stripe, color/stripe, color/stripe, color/stripe.)

I have been buying Cable Matters network cables lately. No issues. 30 foot is $11.50. 3C says it has been as low as $8, but not lower than $10 since the Before Times.

pecosdave, do you have a good patch cable vendor you like?

Could some who does provide an answer, please?
The rest of us only have their own experience, those they speak to, and the hive mind.

Oh, and ChatGPT. Not sure this answer is accurate, but whatever.
me: Why are flat ethernet network cables not reliable?
ChatGPT: Flat Ethernet network cables are generally not considered less reliable in terms of their ability to transmit data or maintain a network connection. However, there are a few considerations to keep in mind regarding flat Ethernet cables that may affect their reliability in certain situations:
Interference and Performance: Flat Ethernet cables are typically more prone to interference and crosstalk compared to round, shielded cables. The design and construction of flat cables can make them more susceptible to signal degradation, especially over longer distances or in environments with a lot of electronic interference.
Distance Limitations: Due to the design and construction of flat Ethernet cables, they may have limitations in terms of the maximum distance they can reliably transmit signals. This limitation might affect performance over longer runs compared to traditional round Ethernet cables.
Durability: Flat Ethernet cables may be less durable and more prone to damage compared to round cables. The flat design may make them more susceptible to bending, kinking, or crushing, which can affect their reliability over time.
Conductor Size and Signal Quality: Some flat Ethernet cables may have smaller conductors or a different configuration of conductors compared to standard round Ethernet cables. This can affect the overall signal quality and may impact performance and reliability.
Heat Dissipation: The flat design of these cables may impede heat dissipation compared to round cables, potentially causing them to heat up more, especially under heavy data transmission loads, which can affect their reliability.
Compatibility Issues: Some network equipment may not work optimally with flat Ethernet cables due to differences in the cable's design and specifications. It's important to ensure that your networking equipment is compatible with the type of Ethernet cable you're using.
While flat Ethernet cables can be convenient for certain applications, such as running them under carpets or along walls where a slim profile is desired, it's essential to consider the specific requirements of your network and choose the appropriate cable type accordingly to ensure reliable performance. If you need to cover longer distances or require higher performance, traditional round Ethernet cables may be a better choice.
Someone on Reddit suggested FS, but I haven't ordered from them yet. Many lengths and types of network cables. Here's an example from my notes.
FS 1.5ft (0.5m) Cat6 Snagless Unshielded (UTP) PVC CM Slim Ethernet Network Patch Cable, Yellow
https://www.fs.com/products/71924...&id=168
Often in racks 1ft cables are too short and 2ft cables are stupid long. 1.5ft cables are a good option to have.
Yes, there is rampant geographic fraud on eBay. The last cheap iPhone case I ordered what supposed to be from Philly, but was shipped from Shenzhen, and took a week longer than promised.

For 1Gbe internet from the ONT along a wall
Over door frames, etc
Light and easy to run, emergencies or hiding
Does not actually meet standards and may not meet specs, crosstalk, and/or wear out/break from usage. Shorter distances might be ok for general use. But longer runs may have issues.
Most people will rarely go above 100 so probably will not notice. But 32awg is a lot thinner than 22 awg most Cat7 is speced for.
