What is was referring to was fiber from Time Warner. It is not offered thoughout their entire footprint, but even in the mostly rural village I work in that has a population of under 3,000, TWC provides dedicated business class fiber circuits. They have a pretty extensive fiber network and provide the fiber backhaul to many cell sites in their service footprint. All three cell phone towers in the village I work in, the Sprint tower and yes even the Verizon Wireless and AT&T Mobility towers are powered by Time Warner fiber provisioned at 1 Gbps. They offer speeds up to symmetrical 10 Gbps, the only limit is how much you want to spend.
Yes, as you said, they are pretty expensive. At work, the DOCSIS connection for 7 Mb/768 Kb (over provisioned to roughly 8/1) runs us $80/month. You're getting a little better deal at $180 for 25/5. The fiber connection was insane, we were paying like $650 for 5/5. Yes over $600 for 5Mb sym with 5 static IPs. When we switched our company phone system over to TWC and went with their PRI over fiber, that was increased to 10/10, and with the bundling discount, the data price dropped in almost half. Total average bill is about $1500 for the 10/10 fiber with 5 static IPs, PRI with unlimited local and long distance calling, 350 DIDs, 5 toll free numbers, a few thousand international minutes, the copper 7 Mb/768 Kb line and two DOCSIS phone lines.
One more thing, TWC over provisions by roughly 20%. You're connection should max out and test out in the neighborhood of 30/6.5.
Good luck!
