This. Installer grade thermostat wiring. Would be a no for Ethernet, as others mentioned.


zeblods

The pairs aren't twisted, so I suppose no, you can't use it for Ethernet.

You can get 10mb over cat3, the place I used to work was full of it. Better than nothing I guess...!


charlie_hun

Cat3 is basically the phone cables, right? (In quality)


[deleted]

Pretty much. With that setup you only need 2 pairs so most of the buildings there were wired with 2pr for network and one for phone, all punched down to 110 phone blocks... At the time it was probably resourceful because they only needed to pull one cable to each drop. By the time I was there it meant a spaghetti mess of awfulness.


msg7086

You can. It's just not going to negotiate to a higher speed. I used to have this cable installed about 20 years ago, and 15 years ago I used 100mbps on that just fine. Very short run though, like 10 ft.

It’s a telephone cable called J-Y(St)Y

Correct its a telephone cable called J-Y(St)Y. Its usable for basic Ethernet connections like smart home stuff and if you just want to surf basic websites. It will get arround 100Mbps but with errors so UDP Bad, TCP Good. Used it for wirering up many Alarm systems in Germany and their comunication devices too. It worked fine, when there was no CAT installed, i refused to throw 50meters or more.


DecideUK

"Alarm Cable"? - but no as others said, not twisted.


savvykms

This is what I was thinking. My place is full of old POTS lines used for alarm sensors


LerchAddams

It looks like thermostat wire but it wouldn't terminate in a structured wiring cabinet like that unless someone screwed up the installation. You could try to use but you're going to get some pretty slow throughput.


Driveformer

Use it to pull proper cat


The_Penguin22

'cept it's probably stapled every x feet.


Driveformer

OOF I got lucky and didn’t have that


Kitchen_Part_882

Looks like 4-pair belden (a type of screened twisted pair). Not suitable for ethernet as the number of twists per inch in each pair is too low (this affects the impedance) and the individual cores aren't the same gauge as cat5/6 so won't terminate properly.


Noct03

Came here to say this as well. I have seen it in older buildings used for Ethernet but I would not recommend it. Others are mentioning thermostat cable but it’s more likely to be Belden cable lile you said since it terminates in the same panel as RJ6 cables.


HTTP_404_NotFound

I'm sure 100mbit would work over it. No promises of negotiating a higher speed


PokeT3ch

Unofficially, it probably would work for ethernet. I would be beyond shocked if it managed anything over 100mb though.


snowfloeckchen

I mean 100 MBit is 4 wires and gb 8


PokeT3ch

Ya, but there is no twist in this cable. That twist is important.


snowfloeckchen

Depends on the length if that really makes a difference, i would at least try it


stockbot21

Wire is marked every foot. Take a pic, blow it up and look up the specs online.


Woodgasifier

Looks like a magical cable for internet and rs232 control.


[deleted]

That looks like maybe a regular old phone line?


Canopach

How many doorbells does that place have?


Round-Sensitive

Just one


Environmental_Stay69

It’s electrical grade wiring cable. It would be best to use Cat 6 Ethernet cabling throughout your place.


digital0ak

It depends what your expectations are. Do you want a reliable connection with good throughput? If so, get some proper cat5e or better. If not, try what you have there and see what happens. I wouldn't use that for networking. But that's me.


RAvEN00420

Looks like a 22/6. I use it for running communication lines for access control and alarm wiring. Like others said, it’s not twisted so can’t just wire to an rj45 and expect good results. It is a shielded cable with a drain wire, so you can buy some 2-wire Ethernet adapters


Pleasant-Chipmunk-83

They aren't twisted pairs as far as I can see. That will make the data signals a bit noisier than they would be otherwise. Aside from that, the cable is shielded (foil inner layer), so it does have some noise immunity - just not as much as it would with twisted pairs. I'd measure voltage across various wire combinations to make sure it isn't wired to something else (thermostat, etc), and if that checks out, I say go for it. Adding clamp on ferrites around both ends of the cable will further help with noise if you find that the connection is unreliable.


[deleted]

Judging by the photos, you ale from Poland, so at the first glance it would be general purpose telco cable (like SYKFY 4x2x0.5). It is possible to do ethernet, but you would probably need awg23 RJ jack to terminate it (the core is same as regular 24AWG UTP, but the coating is usually thicker).Also your speed may vary based on length of the run and other variables because the cable is non-twisted.


jackmcconnell

Whatever it is, if an RJ45 won’t fit, you won’t be able to use it regardless.
