FTTC is not just a poor alternative to FTTH in technical terms. It's also a fantastic way to kill competition. It's difficult to believe this was not part of BT's rationale for pursuing that route.
Why? Because by introducing FTTC, you kill LLU from the exchange, without introducing a suitable alternative.
To remain fully competitive, competitors would need to move from the exchange to the cabinet where they would take Sub-Loop Unbundling (SLU). From the competitors' point of view, the economics of exchange access and cabinet access are vastly different. Moving into an exchange gives you access to around 10,000 lines, whereas a cabinet only gives you access to a few hundred at the most.
On the other hand, if FTTH were introduced from the start, you would have a ready-made replacement to LLU with roughly similar economics: you just replace copper unbundling with fibre unbundling. FTTC on the other hand ensures there is no direct replacement for LLU.
So it's not only a strategy that holds this country back, it's one that affirmatively kills competition and begins the long, dark route back to the days of the Post Office. Ofcom really need to get a handle on what's happening.
