Hello,
I live in a two-story house (living room on the first floor) and the fiber arrives on the second floor in the bedrooms. I have therefore installed my fiber Wi-Fi box on the second floor connected to the ONT box, and the TV box is on the first floor, connected only via Wi-Fi, which has a significantly weakened signal due to the concrete slab.
In order to position the Wi-Fi signal at the center of the house, I was thinking of buying a long enough fiber optic cable to transfer the ONT box and the fiber box to the living room, but a "fiber technician" who came to help me advised me to instead install a powerline adapter next to the arrival on the second floor to transfer the signal from the ONT box to the fiber box via another powerline adapter on the first floor.
What do you think?
If the powerline adapter is indeed the solution, can the adapter on the second floor, which sends the signal to the first floor, also receive the decoded signal from the fiber box on the first floor?
Thank you in advance for your answers.

Hi,
a "technician" told you that?
He's mostly an idiot.
Or maybe,
he meant between the TV box and the internet box the powerline adapters, which is more doable and quite common, although not always perfect.
It's impossible to connect an ONT to a box via powerline adapters because you absolutely need a speed of 1 Gbit/s, which does not exist on powerline adapters.
A direct Ethernet cable is fine, but never powerline adapters, they can’t keep up.
You can use a long fiber patch cord, yes between the PTO and the ONT as well, but a fiber patch cord is more delicate and fragile than an Ethernet cable.
If the cable length is an issue, check out this solution.
Don't you need Wi-Fi in the bedrooms?
If you only have the TV box to connect upstairs, leave the box upstairs to provide Wi-Fi in the bedrooms and possibly some machines with a direct Ethernet connection.

First of all, thank you for your quick response.
So, I would like to provide you with some small details about my problem so that you can better enlighten me.
Actually, I have a Somfy alarm (which communicates via wifi) with most of the sensors on the ground floor, where the wifi is weak since it comes from the 2nd floor, which is problematic, hence my desire to lower the wifi box to homogenize the signal.
On Amazon, I saw these powerline adapters that are 1200Mbps, so they're suitable for fiber, right?:
https://www.amazon.fr/dp/B01F44TDI6?ascsubtag=AM_LN_AF____B________&tag=lmdn-api-21&linkCode=osi&th=1&smid=A1X6FK5RDHNB96
IF I leave the wifi box on the second floor by connecting it to a powerline adapter, I could place the 2nd powerline adapter in my living room and thus have 3 ethernet ports for the TV box, the TV, and the console, and a wifi repeater on the first floor? And that leaves me with a wifi signal on the 2nd...
Otherwise, since this is a renovated house, I have the option to pull an optical cable from the 2nd floor, run it down to the ground floor through the garage, and bring it back up to the living room through the holes I made to pass new electrical cables and thus connect the ONT box and the router in the living room... I would then need a 40m optical cable. It's cheaper since the cable costs only 35€ (compared to 120 for the powerline adapters), but it's more tedious...
And again, Thank you
PS: Once the message was sent, I reread your response and understood that I could therefore buy the connection kit you recommended since it is 40m and less fragile than fiber.
I was thinking of connecting the box on the first floor to bring down the wifi one floor down for a better-distributed signal and take advantage of its multiple ethernet connections for the TV and consoles.
So it's better that I forget the powerline adapters...

It's often said,
I'm going to remind you that Powerline adapters are the Achilles' heel of a fiber connection, even though they boast ultra-theoretical marketing speeds of several Gbit/s (the little g is intentional), in practice, the average speed still lags between 100 and 300 Mbit/s in the best cases, which is perfect for an ADSL connection, but a real burden for a fiber connection.
Not to mention the connection losses at the first interference that comes along.
If you're really allergic to Ethernet cables, although it's possible to run them from what you say, you could switch to a mesh Wi-Fi network, where you place your access points wherever you want or almost wherever you need them, it's more expensive, but much safer and more efficient than Powerline adapters.
If you need higher performance, you can even interconnect them via Ethernet (Ethernet backhaul).

Hello MicaDK,
Indeed, I agree with Brupala, powerline adapters are a hassle, you'll quickly hit a limit.
I had a similar issue at home where the fiber came into my hallway and I wanted a perfect connection upstairs, not via wifi with signal variability issues, so I had to run an ethernet cable which isn't really aesthetic...
I had seen a solution in copper, but I found the same thing in invisible fiber optic, I installed it and it's really incredibly thin and hardly visible.
The brand is discreet lan, here I'll send you the link to the kit you'd need, https://www.fibreos-shop.com/discreet-lan/1450-kit-complet-40-m-discreet-lan-deplacement-box-orange-bouygues-sfr-kit-complet-discreet-lan-compatible-free-connectique-vert-bleu.html
Just make sure to select the kit based on your provider (Bouygues, Orange, SFR...)
I hope I helped you :)
and ... There you go!-
Hello,
it's true that on the fiber connector side, Free uses an SC/UPC (blue) connector while all the others are SC/APC (green) on the box.
The PTOs are always SC/APC.
The two are not incompatible, but there will be a loss of laser signal if the two types of connectors are different.
We have often seen Freebox users putting their patch cable the wrong way: blue side to the wall and green side to the box, while it should be blue to blue and green to green, except in special cases, it works.

You can also directly use a SC/SC patch cable that is longer. Or even
And if needed something longer ...
The problem is the color :-)
You can even connect several together using through couplers. (single mode in the case of a box).

Hello Brupala,
The PTOs are in LC/PC (blue) and the invisible cords in LC/PC.
The difference lies in the cords,
for orange: SC/APC - LC/PC to the invisible cord and then LC/PC - SC/APC to the box.
for free: SC/APC - LC/PC to the invisible cord and then LC/PC - SC/PC (blue) to the box.
This also allows you to distribute an Ethernet network via invisible fiber optic throughout the house using RJ45 to single-mode 1FO gigabit converters. -

It is not connected to the PC, but to the box... ;-)
And it's not that invisible...
but very thin nonetheless (less than 1mm in diameter)
