There is a BT pole right outside my house and I have an ethernet cable that runs from the outside top corner of my house into the inside of the property into my lounge.
Rather than than have a lot of fiber cable tacked around the house is it possible to connect the fiber cable directly to the ethernet cable and then use this to connect to my router somehow?
If I've understood you right, the answer is no.
Fibre carries light, ethernet carries electricity, so they're chalk and cheese.
You obviously can't connect a fibre cable to an Ethernet cable directly, light doesn't travel too well through copper apart from anything else.
However, it might be possible to site the ONT (optical modem) so that you could utilise the Ethernet cable to connect to the hub.
Why do you have an Ethernet cable that runs from the outside top corner of your house running anywhere ?
If you had (for example) an inside Ethernet cable you could ask that the ONT be positioned near it (so the Ethernet cable could connect to the ONT ) , and then the other end of the Ethernet cable could connect to the router, but you can’t have the ONT outside so any Ethernet cable outside is of no use unless you bring it inside the property.
I was under thr impression exterior ONT’s do exist but openreach do not offer one and will not connect to third party equipment. Is that correct?
No, they don't provide exterior ONTs. I assumed you meant the Ethernet cable ran internally.
I think the ethernet cable was there purely to be utilised for a old landline connection.
luckily i do have an internal ethernet cable that i can use to conmect the ONT to the router. I was just wondering if there was some clever poe based thingy that might be able to bridge between the fibre amd ethernet and save clopping a load of cable to the building.
Sorry for the confusion yes there is an ethernet cable that runs from outside to inside. There is also another one internally that goes from where the first one ends to the location of the router.
If the cable outside was used in the provision of a telephone service it won’t be Ethernet , and there is no external ONT so I can’t imagine where you got that impression, probably confusing a CSP , a customer service point , sometimes referred to as splicing point , simply an enclosure where the internal and external fibre cables are spliced together and an ONT , the optical network termination (mains powered)
This might be a bit of overkill but i guess i could use a fibre media converter at each end?
