How about using fiber optic cables for this? I saw a few videos on YouTube showing the installation for home internet

To what end? The runs aren't going to be long enough for fiber to provide a benefit, and the transceivers are more expensive for consumer use like this.

Much easier to conceal. https://lightera.com/invisilight-home-fiber-kit/

Worth knowing in this context: Telephones only want a twisted pair. Ethernet, popular with businesses for decades, also wants a twisted pair. Now, that pair must meet much stricter criteria to be suitable, such as Category 5 (for 100Mbit) or Category 5e (1000Mbit ie Gigabit) - but it really is just twisted pair cable, merely a tighter specification than your phone. Suppose you are a sparky (electrician) and you have…

I had the same thing in the house I bought, it was a nice surprise… there were 6 different phone jacks around the house in great locations for Ethernet (WiFi access points or just for a computer), and they all led down to the furnace room where they attached to a punch-down panel (basically they were all spliced into each other.) To my surprise they were all cat5 cables. With the house being built in 2003 this was su…

My mother moved into a retirement village a while back and I was pleasantly surprised to find Ethernet jacks in every room, in some cases more than one. There was no patch panel or anything which was a bit odd, maybe hidden in a service cupboard, but initially I just needed to get a connection from the router to the bedroom and established that these two jacks there were connected. Hooked it up, nothing worked no matter what I did.

On the next visit, with diagnostic gear to look at the wiring map, I found out that the Ethernet jacks were wired up for phone lines. Some genius had decided to run Ethernet to every room, with RJ45 wall sockets, but wired it up for phone lines, so it was simultaneously unusable for either phones or networking.

Same; this was the nicest unexpected surprise about buying this place. Condo built in 2006 with cat5 . Two bedrooms + living room all wired with rj11 phone jacks. Just snipped those off, wired up rj45, and attached the other ends in my utility closet to a patch panel with rj45 as well. I don't know if it's just cat5 or 5e, but it saturates a 2.5Gbe link and in-wall cable length is about 15-25 meters.

And you're lucky with that build time, if it was more recent it'd probably be CCA or even CCS. When we redid our place a few years ago I went and bought a drum of plenum cable and told the electricians to use that, so I know what went in there. Overprovisioned slightly but who cares, I had a whole drum of cable and a 48-port switch so may as well use it all.

The only problem with this is that for some god-afwful reason, anything built before the 2010s (?) placed electrical and phone sockets at hip level instead of ankle level. So you're staring at ugly sockets all day. So sadly you still have to punch holes. Then again, it isn't that much of a bother if all you have to do is punch a lower hole, relocate the socket and then plaster both holes up and repaint. Especially if…

Make it several weekend jobs are you get multiple lots of kudos from the wife :-).

In France (and probably everywhere) there is currently massive deployment of FTTH (fiber to the home) and removal of copper lines, since a decade.

Does this mean we could have kept the good old copper lines from 60 years ago and still enjoy 1 Gbit internet in residential areas?

I'm so confused why there is no discussion about RJ45 connector being backwards compatible with RJ11 (the RJ11 connector fits appropriately into the RJ45 socket) and that the G4201TM should have a RJ45 socket (like G4202TCP) instead of RJ11 to be most widely functional/compatible (even though you still can use a RJ11 cable with a RJ45 wall socket to overcome this, but you could use RJ45 cables too)...

And some cat5 cables will take gigabit speeds even though they’re not rated for it if they’re high quality enough too.

Cat5 is rated for Gigabit over spans of up to 100 meters. The 1000Base-T spec predates Cat5e.

Oh cool

"across a nice poured concrete driveway" I've worked with DB people and running lines under driveways for telco and cableco is BIG business and they will not find your request to bury fiber or cat5 to be even remotely unusual. The bad news about directional boring is they usually want "like a kilobuck" just to show up. Its a lot of heavy equipment and a lot of dudes to operate it all. The good news is if they're alre…

Probably should have mentioned that it's not a driveway in the US sense, where it's a strip of pavement with dirt on either side. More like a courtyard that butts up against the main house and guesthouse. There's no digging under it from the side. Incidentally, what does "DB" mean in the above?

I would guess directional boring. They can start a bore and sort of drive it around corners.

20 years ago when they were putting fiber in all over the place here, they would bore around a whole cul-de-sac in one go. In several cases breaking every water service line on their way through.

I have converted 'RJ11 phone plugs' to Ethernet in multiple rentals to the delight of the landlord. One should also not that event Cat 5 can carry 1Gbps (instead of 100Mpbs) and Car 5e can carry 10Gbps (instead of 1Gbps) depending on the length and other factors such as which switch is used.
