RCN provides broadband Internet, digital cable TV, and phone packages via three network types: coaxial cable, DSL, and fiber optic.
RCN’s “cable” HFC network is their most common option.
With cable, data is delivered via fiber to subscriber neighborhoods, where the data hops over to electrical signal to be sent via the coaxial cable network, which RCN originally installed for TV services.
leveraging existing copper lines for the last leg of the journey makes cable providers like RCN somewhat slower than fiber, but more cost-effective because RCN doesn't need to invest in fiber to homes.
Their fiber plans will terminate inside or very near the building, allowing download and upload speeds far above those offered through traditional DSL and cable providers.
Fiber-to-the-home is generally considered the best choice for Internet access, and true FTTH packages display the highest speed performance available on the market.
