This obviously doesn??™t include other
necessary capital expenses and the operational expenses of providing a data service
offering to customers, but these costs would be present regardless of the access-network
technology in use.
The costs to build and maintain the HFC plant are not as trivial. To build a modern HFC
network costs on the order of $30,000 per mile of plant (including head-end equipment
costs), and to maintain the network, costs are another $1000 per mile each year [8].
