I will ask the engineer to splice on a new fibre connector for me

They don’t splice on those connectors.
The whole lead in cable from the CSP/fibreDP{if an MDU} would need replacing.

Definitely need a new cable to be installed. Call EE and get them to book an engineer

It likely bumped against other items in the utility room, causing shifting or rotating... I will ask the engineer to splice on a new fibre connector for me.

Just to say you can’t rotate those connectors - well you can but you will possibly damage the face - as they are an APC style connector- which means the face has an offset angle, it’s not flat. This is why the connectors are coloured green (rather than blue to distinguish them from their flat faced cousins). When the rest of the body of the connector is ordinarily present, then it locks the face in the correct orientation. It also stops the ferrule from working its way loose from the barrel in the body.

Rotating the connector will also lead to a loss of light and quite probably also allow dust ingress between the connector faces.

I cannot imagine why any competent engineer would think this was OK to leave. Just sheer bone laziness I guess.

There you go plenty of verbiage to quote the contact centre agent when they ask why it needs replacing! 🤩🫶

I agree. I will quote your word, haha. You can see in the picture that the white box in the lower-left is actually a legacy of the previous 1G ONT case (that Huawei one with backup power unit), which the previous engineer didn't remove because he said it was impossible (tbh it doesn't look good). Fibre cable is introduced there. I have a table next to, piled with clutter above and below, and I guess I may have accidentally bumped into the fibre cable.

Anyway, I am here to wait for the OR Engineer to show up. I might bribe him with a drink.

So they left the old ONT in place. Wow. Staggering levels of sheer laziness.

My original install was from 2019, so that had the older Huawei ONT which was encased inside the larger enclosure which had a BBU (battery backup unit). This can be reused with the newer ONTs - they do fit inside - just use some self adhesive or similar. Once the outer lid is shut they stay in place. This also has the benefit of protecting the connectors better than just the ONT on its own.

I also Brother labeled the outside LED window markings as the light sequence / order is different from the OG Huawei to the newer Nokias, Adtran etc. 2.5G units. This is entirely optional though.

Doing it this way minimises the clutter on your walls and also means you get the benefit of the BBU for power supply autonomy. In any event you don’t at all need both boxes in place, just the most recent one.

Were you there when they did the upgrade or did you leave it to someone else to supervise?

Happy ending.

The engineer came and put on a new green tap on the fibre. Removed that large white box that prevours ONT used. Behind it is a standard well panel hole. I will buy a new panel to make it look neat. Moving the new ONT down so it can be easily accessed without moving the table next to it.

Things learned: The fibre port caused speed issues on certain servers (where some were good, some were bad) and packet loss during gameplay. The actual internet experience was not noted unless tested. ONT indicator was solid green, and there were no disconnections. Putting the EE router and running a network diagnostic via the mobile app allows "bypass" Customer Service and book an engineer visit when a problem is detected.

Thank you to everyone for your help with this.

Yes, that’s the ONT model we originally have. But when we arrived, there was no backup power supply inside, only the ONT. We have a Zyxel 2.5G ONT now.

Great. 👍

It’s possible they simply put on a new “field-fit” SC-APC connector, depending on when the install was originally done. Otherwise they would have pulled in a new cable that has the SC-APC connector factory fitted (more durable and rugged than field-fit type connectors) and run that new cable back to the CSP.

Either way, sound like it was properly sorted. So well done.

“field-fit” SC-APC

Yuk …. naaaaarrrsty
