My home is cat5e wired and I have 1gig fiber. I get near 1 gig speed."
"near 1 gig"

How do you live with yourself? You need Cat8 now!

:p

I also have 1gb down 1gb up fiber at my house. I built the house with Cat6 running everywhere. When the fiber company installed the ONT(router) they used Cat5e when converting from fiber to ethernet.

I get 950-980mbps up and down.

Quote from rockdd :
Technically ANSI/TIA spec compliant CAT 8 copper cabling can support 40Gbps up to about 30m. Designed for datacenter usage (e.g. rack to rack).

Also, spec compliant copper cabling allows for CAT 5e up to 100m at 1Gbps (2.5Gbps & 5Gbps also possible due to new spec lowering the signaling rate). CAT 6A is designed for up to 100m at 10Gbps. CAT 6 is generally not deployed if 10Gbps support is planned because it's only designed for 10Gbps at reduce lengths (~55m). CAT 6A or fiber would be the preferred choice for 10Gbps.
Came here to say this.

For home use edge cases, Cat6A is more than enough. For most home users, Cat5e is all you need, and if you're running something in a wall, by all means, future proof it with Cat6 (10Gbps up to 180ft/55m) or Cat6A (330ft/100m).
Quote from BrightWealth901 :
Also, beware, I've read that some cat 7/8 cables have a special connector that won't work in standardized rj-45 ports, but that was before cat 7/8 standards were finalized. Not sure if standards are final, and what the outcome was.
That was for Cat7 with TERA [wikipedia.org] connectors.
Quote :
Most manufacturers of active equipment and network cards have chosen to support the 8P8C for their 10 gigabit Ethernet products on [3] copper and not the GG45, ARJ45, or TERA. Therefore, the Category 6 specification was revised to Category A to permit this use; products therefore require a Class EA channel (ie, Cat 6A).
As of 2019 some equipment has been introduced which has connectors supporting the Class F (Category 7) channel.
Note, however, that Category 7 is not recognized by the TIA/EIA at the time of this writing.

As of 2017 there is no equipment that has connectors supporting the Class FA (Category 7A) channel.
Category 7A is not recognized in TIA/EIA.

Anyways, there's no point in buying a Cat8 cable, and considering it's UGreen shilling, it might actually be worse than a good Cat5e/6/6A cable.

If you're running your own wiring, you're buying a roll of plenum rated Cat6A anyways, and if you're Joe Sixpack buying patch cables, just grab Cat5e...

When upload speeds measured in hundreds or even dozens of megabits become common in the US, let me know! Those of us with symmetrical fiber are in the top 1% of the 1% when it comes to Internet speeds in this third world country. If people are "lucky" enough to have cable, they've got what, 20 Mbps tops?

And guess what? I was too lazy to replace the 10m or so of flat Cat5e I ran across my apartment to my desktop when I upgraded parts of my home network to 10GigE, so I just kept it in use. Both ends (NIC and Netgear switch) support 2.5/5GBASET, so it just auto-negotiated at 5 Gbps with no intervention necessary...

Anecdotes are not data but our 20 year old home was wired with Cat5E running 100Mbps. Some years ago, I upgraded to 1G everywhere and have recently tested all links at 2.5G with real NICs and switches :-)

Quote from oxyi :
40gb baseT does exist. You can do interconnect or hook up to supported devices.




40GBASE-T is a port type for 4-pair balanced twisted-pair Cat.8 copper cabling up to 30 m defined in IEEE 802.3bq.[118] IEEE 802.3bq-2016 standard was approved by The IEEE-SA Standards Board on June 30, 2016.[119] It uses 16-level PAM signaling over four lanes at 3,200 MBaud each, scaled up from 10GBASE-T.

There are no devices on the market that support it even though the standard exists.

What consumer devices support Cat 8? None that I'm aware of.
Devices don't need to support a physical spec of a CABLE. The only thing devices are concerned with are the connector and protocol those cables transit. Not their spec.

Quote from Ebbi :
The guage wire of the matched pairs matters. I agree on not hitting 40Gbps, but I also know from installing ethernet cable (as a job, and now on the side) for 20+ years that yes... the cable matters. Cat 5e is fine if you're rocking out your 100 Mbps Comcast/Spectrum internet over wifi and just need the connection from router to (Networking/WiFi)device.

But if you're rocking some of the new(ish) 1 or 2 Gbps Fiber connections, you minimally want Cat 6 installed, and especially if you're hardwiring anything. Go ahead and go run some speedtests.

Don't take my word for it, you can find all the info you need all over the internet.

I don't know how you got so many up votes for a completely false statement claiming to be an expert while simultaneously stating that cat5e can only to 100Mbps. cat5e can do 1000Mbps just fine, the only time you want cat6 is if you are doing long runs like wiring your house for Ethernet, the 6ft cable mentioned here is not a long run. On top of it, the product here is a cat8 cable, pretty much useless for any home user and typically only used in data centers.

I see that UGREEN shills are spamming their trash everywhere.

I've owned a handful of Ugreen cables over the last two years including an almost $100 fiber optic HDMI cable and they've been great so far. I think the Cat8 thing is a little silly but the $100 cable at the time was the cheapest on the market and it's done its job fantastically.

Docsis 3.1 does gigabit down, not symmetrical though. Mines 40 Mbps up I think, with Xfinity.

I would like to wager all my savings that this "Cat8" braided cable is less good than an average Cat6 cable.

Well if you've been installing cable for 20 years, then you'd know that Cat 5e is good for 1 Gbps.

Though if you somehow have a connection faster than 1 Gbps, then sure, upgrade to Cat 6. The price difference is negligible, and it allows you to futureproof yourself.

just as an FYI in our area at least our cable vendor doesn't even carry cat 5e. he said if a customer asks for 5e they just install cheapo thickkkk cat 6

That's funny, cause the internet says that CAT5E and CAT6 are both rated for 1gbps at 100m. CAT6 is however also rated for 10Gpbs at 100m.

So it seems your statement isn't entirely accurate. YIPES.

Quote from supersteals :
Many comments around Cat5e usage - Cat5e standards are one thing, but quality of cable matters as well. I had purchased a generic 50ft Cat5e cable to run between my access point and Router.. I kept getting speed just around 100 Mbps on WiFi. . It took a while to realize this because my internet is 200 Mbps, and I chalked up the speed to WiFi issue. One day I noticed that the AP was only reporting 100Mbps connection speed.. and after troubleshooting realized that this was due to the cable.
I purchased a yet another generic Cat6 cable (with better reviews on Amazon) and I finally get 200 Mbps on WiFi.

So cable quality matters, now if the run was say only 10 ft, I am pretty sure Cat5e would have worked just fine around 200 Mbps, but not if I had internet speed of 1Gbps…
Well, I think the discussion is assuming that the cables actually MEET the CAT5E or CAT6 standards. Your cable clearly did not. Certainly if you are unlucky enough to have a garbage cable it won't matter what CAT rating it says on the package!

Oh man, you crack me up. Don't go saying you live in a 3rd world country to anyone who lives in a 3rd world country. You'll get slapped silly for your blatant disregard for you American privilege.

You know why our internet is slow? It's because infrastructure for such a sparsely populated country is high. That's right USA is one of the least densely populated countries per square mile. We are so lucky that we don't live on top of each other in shoe boxes, even if it does keep us from having high speed fiber at everyone's house!

but yeah, I wish I could get fiber LOL.
