光ファイバーインターネット Fibre optic cable broadband

Some fibre optic services don't quite get the fibre optic cable all the way to your house, to do so for every house would mean digging up an awful lot of the UK, so some get very close to your house with fibre optic cables and then use older cables that are already installed for the last few yards.

There are two main types of fibre optic provision in the country at the moment:

Fibre To The Premises (FTTP) - This is where you actually have a fibre optic cable all the way into your house and you use a fibre optic router that can read and send signals using laser light. This is actually a very rare type of broadband provision in the UK at the moment, and is only available in a very few areas. As the fibre comes right into your property there are no problems with loss of speeds at all, and some FTTP broadband providers can offer speeds of up to 1Gbps which is incredibly fast, and on a par with the very best broadband networks in the world.

Fibre To The Cabinet (FTTC) - This is where the fibre optic cable does not quite make it all the way to your house, but instead reaches as far as your local street cabinet. You've probably never noticed your local street cabinet, though they are incredibly common, they are usually green or gray (though confusingly some may also be underground, but this is rarer due to the flooding risk) and there will be one within a hundred yards or so of your home.

Between the street cabinet and your house the broadband supply will use your old BT copper telephone wire (or in the case of Virgin Media customers will use coaxial cable). As the last section is not on actual fibre optic cables there will be some loss in speed compared to FTTP services. Current maximum speeds on FTTC fibre optic is 100Mbps for Virgin Media (though they are trialling 200Mbps) and around 80Mbps for BT telephone line based suppliers. However these maximum speeds will probably rise in the future. The vast majority of current fibre optic broadband customers are on some kind of FTTC fibre optic supply.

The advertising governing body (the ASA) has deemed that all type of FTTP and FTTC broadband can be collectively described as "Fibre Optic Broadband" and for the rest of this buyers guide we will use the term for both types.
