No you only have ONE fibre and by magic and flashing lights and 'Time Division Multiplexing' it's all sent down ONE Fibre if you have more than one ISP service they change the ONT to a four port one (These are four Ethernet outputs), you do not need anymore 'drop' fibre lines.

In theory you can send unlimited amount of "light" signals down a single fibre cable - its dependent on the technology at either end and the quality of the fibre. TDM is the most basic multiplexing system.

Rumour has it that they are fitting Nokia ONT’s on Huwawei exchange stuff now.

My understand is that it would still work apart from any proprietary testing/diagnostics, is that others understanding?

you just nab a second fibre from the csp.

This is only true for the older manifold FTTP deployments (pre-connectorised cables to the property).

I didn't realise that had changed with the newer conectorised installs .. I do understand where i screwed things up with that comment.

Yeah legacy FTTP (pre 2017-ish) was blown fibre tubing from the manifold (hence its name) into the premises CSP. I believe Openreach used to blow a 4-core fibre bundle (aka blown fibre unit) about 1mm diameter total that contained within the bundle blue, orange, green and red fibre cores - used in that order, from the manifold to the CSP.

These days of connectorised Openreach FTTP, its just a single core of glass in that drop cable from the CBT port. If you need more cores, they need to hook you up to another port (difficult in some urban areas if there are any spare ports!) and then run another drop cable.

Openreach still used blown fibre to install leased lines into premises. I have a 12-core fibre bundle in 'shotgun' tubing (one used one spare) - the bundle about the same overall size as the 4-fibre bundle above, coming from the fibre joint enclosure in the footway chamber up to the equivalent of an FTTP internal CSP - maybe just a smidge larger 😎

When they ran the internal leg (for the second time, long story) they didn't even bother to get the compressor out, they just pushed the fibre down the tube by hand straight off the bin lid sized 2000m reel. Went in like a charm!

Huawei OLT's have always been able to be software configured to be compatible with other brands of ONT - after all they are GPON standard compliant. However for whatever reason (possibly operational, support, monitoring and management software/tools training etc) Openreach decided to keep their estate single vendor.

Haven't seen this happen yet.

I've seen quite a few examples of installs not being able to be completed because the engineer brought a Nokia ONT instead of a Huawei ONT.

In 1 case the engineer spent over 2 hours (including on the phone with the DCoE) trying to get the ONT registered without success.
Another engineer was sent with a Huawei ONT which worked immediately.

The OP's install couldn't be completed initially as the engineer tried (and failed) to register a Nokia ONT to the Huawei OLT.

So if it is happening, some specific configuration needs changing as at the moment how OpenReach have the OLT setup it certainly doesn't work automatically between Vendors.

I notice the PON light on the ONT was flashing, he did as well.

The Quinn guy had to talk to BT OpenReach because he had a flashing PON light, he had only fitted a Nokia ONT instead of a Huawei ONT, but BT OR chap had to re-configure things, then we got the Solid PON light.

They could if they wanted to though John. Its not technically impossible - although I have no idea how Openreach currently organise themselves in terms of OAM software tools etc which may be the reason they strategically deiced to keep the OLT estates single vendor.

At some point, probably at the expiry of their long term support contracts, Huawei will gradually exit stage left as they are pushed out of markets.

So it seems.
I initially read that as he had changed the ONT.

Would be interested to hear from APTMAN if he does indeed have a Nokia ONT.

It can definitely be done on GPON.
Like I said it doesn't work automatically with OpenReach's setup.

I know it can be done on GPON.
I just know it isn't as simple as scanning the ONT barcode like with a normal install.

I'm a bit surprised nobody picked up on APTMANs original comments about the Nokia ONT.
If I had read his post correctly the 1st time round I would have commented that it's the 1st we've seen this happen.

He mentioned a few times on the kitz forum that he was going to ask his ISP for a 4 port ONT to be installed during his install as he intended on running multiple services.

I asked exactly that in 2019, and was told it wasn't possible - no 4-port ONTs for new installs.
