FTTC guarantees 15Mbps per customer, so for each 66 customers they provision a single GigE to the cabinet.

When it reaches the fibre within the FTTC exchange/headend it is then handed over to the ISP on GigE or 10 GigE and the service provider then decides how to contend the service from there.

FTTC doesn't suffer the same skinny pipe issues that cable does, it's guaranteed bandwidth to the cabinet, zero contention, guaranteed to the point where there's never going to be any contention between cabinet and exchange, and fatter core network pipes from that point on.

Doesn't mean there's no contention, depends on the service provider, but it's deeper down the network.
