Open Loop is pretty common in Europe. I have one electricity line, one gas line, one phone line but I can choose from multiple providers for each service. For gas and electricity whoever I buy from is responsible for putting the correct amount into the network. For the phone line for fiber to the cabinet internet they hook up their network at the exchange and patch my through. In all cases the providers have to pay a fee to the infrastructure owner that's a fixed regulated rate which pays for maintenance on the network. There is now point running more than 1 fiber optic cable to each house just like there isn't a point running more than one electricity or gas line to each house.
