My company throws these away. Manager claims they are bad and the connections over it are unstable. They are cat6a. I measured them with a Fluke and Fluke claims it's capable of 10g. How stupid are they?

Yes free for me. Took 10 5m home. From the trash bin so it's not stealing, right?

You'd actually be doing them a service if they pay for trash by volume. Also keeping them out of the landfill.

We don't use them cause they're a security concern apparently
If someone sneaks into the office and plugs into one of them it's fucking over or something
I feel like if someone snuck into the office they'll be able to do whatever they want regardless but what do I know im not a scammer i mean sysadmin/ciso

How do you "plug into them"?
Also if they are that concerned about security and have the possibility that someone tabs the cable, they should use fiber-optic, no?

Ah yes that's so secure, because an attacker wouldn't just unplug it and spoof the MAC address. Bunch of fucking retarded lobotomites.

I think it's more a concern of someone accessing the intranet/local servers.
Like plugging in a dodgy/compromised usb

If someone has physical access it is actually completely fucking over anyways regardless of what security measures you take. If a server, switch, pc, whatever was physically compromised all you can do is throw it in the landfill.

You couldn't access the servers with fiber wires.

Flat cables don't have shielding, so electrical interference affects them much more than round cables with proper shielding.
A properly shielded 10gb flat cable is twice as thick as that in the picture, since I've got a couple of those in my house.

This. But I'm pretty sure flat cables aren't actually standards-compliant.
Not that it should matter since ethernet is quite resilient.

I remember they have to have some sort of twisting on each pair to be compliant, some being more twisted around than other, while flat ones have them in parallel.

They are twisted. Otherwise having RX and TX +/- doesn't make any sense. In OP pic you can even see that they are twisted from the ripples on the isolation.

I have my own company which I got ISO 27001 certified.
One of the requirements was not having exposed ethernet ports outside the locked server room.

I could still have them if I secured them and wrote a detailed description why they're necessary, how I secured them, what my risk assessment is, how I mitigated any risks, what future mitigation might be necessary and when I plan to do them.
....or I could just remove the ports.

Not twisting would be madness.
They're probably 4 twisted pairs side by side.

>capable of 10g
Great then you need network gear that does that
then you need storage that can saturate it

I will never understand why tards will jump up and down to 10g when their internet is 1gbps at best and their "nas" is only peaking delivery of media at ~80MB/s

As retarded as it sound, it's still stealing if done on private property.
It's a grey area if done outside private property.
Don't get caught.

That's nice. Can you guarantee the entire shipment is to the same standard without fluking every single one, and that they will also meet spec after install?

You don't pay the fancy-enterprise-cable premium for a 'better' cable, you pay it for the guarantee that it is at a minimum good enough to meet spec, and if it's not you get it replaced on their dime.

anon, you dont need a 10g uplink if you want to send data within your local network.
yes, your 1g uplink is a bottleneck, but even if you were to somehow get a 10g uplink, who do you send your data to that also has 10g uplink? the only realistic answer would be a separate building that you still have control over. so that you can link your two buildings with 10g. but 10g to the internet doesnt make sense.
i myself have a 10g NIC in my PC as well as my home built NAS, simply because it cuts down my full disk backup time from like 3 hours to 20 minutes.

Anon the pairs are also twisted around eachother and (cat6+) have a plastic core that further reduces crosstalk. Twisting the pairs around eachother means that a single pair doesn't receive more crosstalk than another (i.e. in a flat cable, the pair on the side of whatever is causing interference will receive more)

it is and it isnt. technically someone could go after. humanistically, kinda of a dick if you do. some places just gave away pcs when they were past EOL.
my current comapny doesnt though and will make sure its not because theyre so big there are groups looking at them to make sure theyre not doing ewaste and if you take one of the machines home and then throw it out *they* supposedly will get flack for it.
sometimes the green agenda works against itself.

Every 3.5" hard disk made in the last 10 years can saturate 1000BASE-X by itself.
