ONT extension

Does anybody have any experience using a fibre extension kit for their ONT?

Such as this linked below?

Going to be doing some decoration works soon and I wondered if it would be worth burying on of these in the wall. Just want to know if the are reliable?

You don't need one. A single mode fibre patch cable with SC/APC connectors both ends and an SC/APC fibre coupler will be fine. Coupler between the incoming Openreach cable and your patch cable.

If you want to hide the extension get an invisible cable from Ali Express and the coupler to go with it. Nothing super interesting about the kit all passive and little to go wrong.

Thanks for the info

Don't bury fibre cable in the wall, bury a conduit if you have to put something in.

Big enough to get a pre-terminated cable through?

A preterminated cable will go through a 20mm conduit with no issues, use the swept bends rather than elbows though

Thanks

No doubt you want to move the ONT as you don't want it showing where it is, but you need to be careful with fibre, it is easy to damage, and what happens if something goes wrong at some point and Openreach have to come and sort it out? They not be happy that you moved the ONT.

Would it be easier just to have an Ethernet cable going from the ONT to your router?

Not really. Far more robust than people who've never handled it give it credit for. Nearly every issue is with the connectors.

That or when someone like me is trying to clear a tangled mess and pulls a little too hard and snaps it in two (luckily only multi mode running to a PC) as long as you don't do that its probably fine.

You normally can feel the bend limit on fibre cable, unless you are silly, it won't break. That said, the amount of times i've not got lc connectors into the module, and also knocking the sfp module on surrounding furniture worries me more than breaking it.

Yep, in my case I had a load of fibre tangled together behind a desk that had no visibility so pulling was the only way, it was 15 meter long which didn't help and it went through cable trays and ties so some force had to be used and then snap, its not a big deal if you have a spare cable or splicer available, in my case I can get hold of both easily so wasn't an issue. At the end of the day your more likely to get issues from dirt on the connectors.

how strong are the transceivers (sfp+) i've managed knock on my desk legs 🤔and other objects

Set up a Fibre network at my partner's house and yes it is more robust than some people think it is, but is it worth the risk? If I break fibre on the network I can replace it, but if it gets damaged going to the ONT, that is a different thing. Also, as I said above if Openrerach had to replace the ONT they may not be so happy.

I can see mine here is bent more than 90 degrees, but its working and I wont touch it.

Never broken any of those yet and have dropped a few, the switch is more likely to go first realistically, that is unless you are trying to break them or are using them in a kitchen / high dirt environment that kills electronics generally.

The whole point of the coupler and patch cable is the man is using his own cable for the extension. It breaks he replaces it, no harm done. The ONT isn't going to keel over because of a fibre break or being moved. The scenario I mentioned is how I believe your fibre is installed with a connectorised fibre, coupler and an internal fibre.

OP could use Invisilight for discretion. If you've a copper cable that's 0.9 mm in diameter that'd be good to see. Point is it's nothing to worry about and doesn't endanger the Openreach fibre or ONT.

Indeed. They are usually DoA or good to go for a long while. As long as attenuation is used where appropriate to ensure optics aren't overdriven.

As long as they don't damage the fibre going into the ONT and as I said before, if the ONT goes belly up for any reason and Openreach need to renew it, what will they say about it being moved? Does Openreach treat their ONTs like they do the master phone socket?

At the end of the day, it is up to people if they want to move the ONT and take that risk.

Agreed, I had ordered a 25m of SC/APC to SC/APC cable so that I could move the Modem (ONT) from the Living Room to one of the spare rooms upstairs the back of the house.
Sadly that arrived with I think 2 breaks in it so got a refund and got myself an Armoured version which works fine.

When installing the new cable I thought I had broke it due to it got tangled up due to being loose and no on a reel, but it was totally fine.

But yeah I agree, they either arrive broken or they work fine.

I don't think the ont is being moved. It's an extension.

Why would they need an extension if it is not going to be moved? Maybe they need a bit long fibre to bury into the wall, but the fibre is so thin it can be painted over and not seen.
