Hi, if I was to trench fibre to my property approx 450m through a field what spec cable would be required if one of the alternative networks where to use it to connect to nearest roadside pole/duct? the cable would be in its own duct so it doesn't need to be armoured.

It would need to serve 2-3 properties so at least 4 core fibre. Also I wouldn't want to later on be limited to speed so would prefer to have it futureproofed to 1gbps? if possible.

Would 8 Core OM4 50/125u duct grade be suitable?

Thanks

I don't think any operator would consider connecting you if you were to do a DIY job of that kind. That's because they wouldn't take any responsibility for it, and who do you think would be accountable if you needed an engineer to address a problem in the future. That's why anything to be done beyond the master socket (DSL) or modem (fibre) is the responsibility of a telecoms company.

That depends on the optics each side, nothing to do with the fibre in the ground (to an extent, but the distance you're running here will be fine). Do you have the optics and equipment to terminate the fibre at your property?

Have you already agreed a connection with another network? As already mentioned I can't see any network provider agreeing to connect you up to their network via a DIY job like this

In any case you don't want any multi-mode fibre... Though that's really a bit academic, as others have pointed out already.

Is it possible they might be willing to use the ducting?  But I'd imagine there are certain standards it would need to conform to.

After all, its not the fibre that is the expensive part.

@tomtom  As Alex Atkin says Openreach have been known to use customer installed ducting but you would need to negotiate with them to find out the required specifications.

They are difficult to even contact at all so trying to arrange such a project would be a challenge.

Theres info about ducting here aimed at new site property developers. 
As you'll see, as long as the ducting conforms to their standards Openreach may use it. However they still remain responsible for cable installation expecting the developer to have installed draw ropes for their use at each end of the ducting.

Theres some more handbooks and guides for developers here

This absolutely. The trouble with using your fibre isn't actually technical but about who's responsible if something goes wrong. They need a demarcation point between the home installation, the bits that are your problem, and theirs. Using your fibre blurs that as your fibre is feeding their equipment.

You put a JCB through the duct and cut their fibre you repair the duct, they repair the fibre and send you a bill. 😊

The only complication is that it isn't just one person the duct is serving. Previous examples of this I've seen the duct was down a private drive. That basically meant all on one person's property so it's like one giant drop. In this case it's a part of their access network serving multiple people. They'd have to 'adopt' it and other than Openreach and VMO2 I'm not sure if any others would be prepared to do that.

[Alex Atkin UK]

The irony being presumably if Openreach adopted it THEN PIA kicks in and the alt-nets would come along.

[XGS_Is_On]

Nope: they'd need wayleave.

[Alex Atkin UK]

Really?  That seems counter productive.

[XGS_Is_On]

It's the law. Wayleave covers Openreach plant. PIA fibre in Openreach duct isn't Openreach plant and the PIA customer can't maintain in case of duct blockage or collapse.
