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

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

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.
