What full fibre actually changes in an office

A supplier will call almost anything fibre. The distinction that matters is where the fibre stops.

Full fibre to the premises, FTTP, means the optical line reaches your building. Fibre to the cabinet, FTTC, stops at a street cabinet and finishes the journey on a copper pair. The second one can still be sold with a fibre-shaped advert. It is slower, and it gets worse as the copper gets longer.

What changes when the line actually arrives at the door is usually quieter than the brochure. Files sync without the afternoon queue. A video call stops being a gamble. A hosted phone system has a chance of sounding like a phone system, because the calls are no longer fighting a line that was already full.

What does not change is the far meeting room. If the Wi-Fi was weak before the install, it is still weak. Fibre does not walk through brick. The router matters as much as the circuit. A box nobody can log into, with a configuration nobody wrote down, will waste a good line.

Ask three plain questions before you sign. Does the fibre enter this building, or a cabinet? What speed is left when the office is busy, not at midnight on a test? Who holds the login for the router the day after the engineer leaves?

Lead times are part of the answer. A wayleave, the permission to bring a cable across someone else's land or a landlord's riser, can take longer than the install itself. If the building needs one, it should be said at the start, not after the order confirmation.
