Am I getting it wrong
Is Super fast fibre different from Fibre optic ?
I am with BT provider with BT infinity which I am told has fibre optic.
What Openreach calls "superfast fibre" is the same as "fibre optic", and shows that at least some of your broadband service is provided over fibre. For a few people, this fibre goes all the way from the exchange to the home; for most people, the fibre goes as far as a local street cabinet, and connects to the final bit of copper into the home.
The "superfast" label is used to indicate it can go faster than 25Mbps.
BT Retail (the ISP part of BT) uses the "Infinity" branding when they sell a "superfast fibre" service to you. It is the same thing, just two slightly different names.
I am switching to Vodafone . ( landline ,broadband internet ) Vodafone tells me that I can not get Fibre optic in my area which I found strange confusing as BT told me I have fibre I am paying them for that service
Unfortunately, the customer service agents at ISP's aren't always given the full details about *why* a "superfast fibre" service isn't available to you ... the computer just tells them "no", and they relay the message to you.
You've checked independently, and found the reason why: the fibre equipment is fully utilised, and cannot accept more orders.
In order for any more orders to be accepted, BT will have to install some more equipment - which might be as simple as plugging a new linecard into the cabinet, but could be as complex as installing a whole new cabinet.
Until then, a new order will only be accepted when one of the existing fibre subscriber cancels their service.
Would there be a risk that if the OP went to Vodafone that he could be put on the waiting list for their cabinet as its at capacity and his existing port be used by the next in the waiting list?
There is indeed a risk that, if the OP cancelled their BT service, their port would be freed-up and grabbed by a different order. Leaving them with no ability to order a fibre service with Vodafone.
The "waiting list" and "order queuing" mechanism is very new. I don't know how many ISP's make use of it yet - presumably not Vodafone though.
