Anyone know the correct dimensions for the new ONT housing

[link to this post]

Openreach have published the following fact sheet but the sizes quoted for the new ONT housing/case that can hold either a Huawei or Nokia 1+0 ONT is clearly wrong as the sizes quoted are for the larger legacy case that also housed a BBU, the new one is a smaller compact case which appears to be slightly bigger than a double socket.

Does anyone know what the correct sizes are?

That's not a ‘larger legacy case’ shown in your link ....

not seen one of whatever it is, but it’s not the old style housing.

The case holds the ONT at one end ( the right hand side shown in the photo) and the other end is for cable management.
The ONT can still be mounted directly without the case if required

would be nice if they had thought to provide suitably spaced holes to fit over a single back box. looks like it could be done as the ont sits to one side

From the developers guide "The enclosure fits over a standard single or double back box, with mounting holes that allow horizontal mounting over a double back box or vertical mounting over a single back box."

An interesting document.

A few queries,

1) it appears to be for installations where the FTTP is via an underground duct? Are these casings also used for an overhead FTTP installation?

2) I note that the pre-connectorised cable is available in 2, 5, 10, 15, 20 & 30 metre lengths. What happens if the longer lengths are a few centimetres too short?

3) What/where does that black connector connect to?

4) This new casing with external capping does not seem to utilise a CSP?

Sorry to be a pain!

Cheers!
