Update 15 June 2018
Hi All,
Well believe it or not I am finally live with my fibre. YAY!!!
It only took about 9 months and 10 days from ordering to completion.
Yesterday two very friendly OR engineers arrived to perform the final commissioning of the fibre inside my house.
They were pleasantly surprised to find that the fibre was already inside my house and that they didn't need to run it from the outside. I explained that was done months ago and they were very surprised. Must be some good internal comms in OR.
Anyway they spent about 1hr mounting the ONT and stripping the fibre cable down to the actual fibre (which I didn't realise was so thin) so that they could add the connector.
It actually took them 3 goes to get the connector working well but they think it may have been a faulty tester of the quality of the line rather than the connector.
They connected the fibre directly to the ONT. No CSP or any other joint box etc
They tested the line and showed me I had 14db which they said is good.
We then wasted a bit of time testing the line with their bt router with them not realising I was getting my fibre through Cerberus and not BT. As a tip to others make sure they are aware of this as they assume you are a BT customer.
I couldn't get my routers to work (tried 2 different ones) and I called Cerberus who were very quick to help.
At first their was confusion why the line was not working but it ended up being a simple case of the order needing to change from in progress to complete on both OR and BT's systems.
I let the OR engineers leave as they assured me everything was physically good with the line.
It took 2 hrs for the order to change to complete and my router immediately managed to connect to the cerberus systems.
By the way I am using a brand new Unifi USG gateway / router.
So now on to the speed results:
My initial speed test was disappointing. I was only getting 100mb but over 30mb upload.
I checked my router and realised it was syncing with the ONT at 100mb rather than 1gb over Ethernet.
This stumped me for a bit and after some googling I decided to change the Ethernet cable. Intermediately my router synced at 1gb to the ONT.
So I ran tests again.
My first run I got 332 / 32 about. I was very excited. However about 5 mins later my line dropped. It came back up and I retested.
This time I constantly got just over 300 / 30. Around 308 / 32.
I think the ONT re synced at a slower speed to the OR network after it first dropped to get more stability.
So far it has been stable since and I was expecting 300 and not 330 anyway.
My ping times seem really good at 3ms on speedtest.net.
I have discovered a potential issue though that I wanted to check with you guys if it is an issue.
If I upload a file and then simultaneously download my download speeds more than halve. The download speed drops to around 120mb.
I thought one of the advantages of fibre was that the upload and download channels don't interfere with each other like dsl does.
Is my thinking wrong and is this expected behaviour with fibre?
I'll try post some photos later of the ONT as it seems to be a new one with the batteries built into it. They are irrelevant as I am not getting voice with the fibre but it seems Ofcom mandate that the ONT has battery backup for emergency calls no matter if you have voice or not..
P.S. Dslchecker now shows 330/50 fttp as being available. I assume that change took place as soon as my order changed to complete.
