FTTP install without grey box

I was speaking to an Openreach guy and was querying about the grey box.

He told me they dont always fit the grey box and can take the cable straight to ONT

In the case of an existing duct from pole to existing telephone point, the new fibre cable can be pulled in directly without any need for the grey box.

I don't think so!

The internal fibre is pre-terminatef  with a plug to fit the ONT. The 'free' end of that must then be spliced to the external fibre at the CSP ( grey box )

AFAIK it's not possible to fit a plug to the external fibre to allow it to connect to the ONT

@Bella123 I think the guy was telling you porkies - the FTTP uses totally different technology and cabling - and does require a CSP (outsisde grey box).

@Bella123 

That was how they did my install - back in late 2017. This was before they introduced the grey box for outside.

Re: FTTP install without grey box

There is a smaller internal CSP that can be used, maybe that's what he meant. But AFAIK, there's no way to request one, just pot luck as to whether the installer has one onboard & is willing to fit it.

Re: FTTP install without grey box

When i was questioning him about fitting the grey box he said 'we're supposed to but dont sometimes' like in the case of underground duct going directly to phone socket, how can they mount an external box in that case without digging outside to find the duct.

I think they use something called a field fit connector to connect the black wire to ONT

Re: FTTP install without grey box

They know where the duct is - otherwise how did they route the copper cable. IIRC, they don't, and haven't for many years, use 'field-fit' connections.

They may know where it is but they wont be digging up the driveway!
