Replace coaxial cables with Ethernet

[confy]

Dear forum,

I want to apologize for using English but unfortunately my Swedish writing skills are not enough to write this post

So my house is full of coaxial sockets and channels and I was wondering if it will be possible to pull the cables and replace them with Ethernet.

A typical socket in a room:


Those channels seem to go up to the attic and by having a fast look on my attic I was able to found something like that:


Is anyone aware what kind of channels are those? Do you think that are channels for the coaxial cables? Are people here which managed to do something similar (replace coaxial with Ethernet) ?

Thank you all!

It's normally standard cable channels so you can swap the coax's with CAT. If you manage to pull out the coax's, they can be quite heavily stucked.......

 

[hempularen]

The channels may be for the coax cables or for elektricity or old phone lines. It should be possible to pull ethernet in the same channels. It may be tough to get more than one cable in each channel.

Those are ordinary 16mm conduits for cabling, nothing out of the ordinary. To answer your question - yes it’s fully possible to replace coax with Ethernet cabling. I would recommend UTP variant with less shielding in case you are planning on having two cables in same conduit since they take up less space than STP/FTP (which are probably overkill anyway). We’ve replaced all telephony cabling and sockets in our walls with Ethernet.

First thank you all for you replies, they are super helpful!

I am thinking to go with CAT6 UTP to be more future-proof, max distances are around ~30 meters so I can achieve speeds up to 10 Gbps and PoE which I am mostly interested!

For those short distances even CAT5e would probably work for 10GbE.
CAT5e are usually thinner than CAT6. With some luck and lots of cable lube you might be able to get three cables through.

Coaxial cables are usually run in series, which makes them non-ideal for ethernet unfortunately.

10 Gbps and PoE

These 2 are mutually exclusive. Anyway that is just nitpicking. If the cables are really stuck in some place where you can not replace the tubing you can run ethernet via MoCa adaptors.

A small nitpick: classical EtherNet was done from the beginning for RG8 - ie coaxial cable but this is i believe RG59 ie for cable tv. Which also at one time was used for EtherNet (multiple ethernet connections and one or two cable tv signals.)

Though it should be possible to pull through twisted-pair cabling in the ducts.
