We get asked constantly, "Isn't fiber risky? What if wireless is better?" Fiber is a highly stable, very reliable forty year hard asset that you can take to the bank, because unlike nearly every other kind of community infrastructure (roads, water, sewer), you can increase fiber capacity without digging new ditches or having to hang more fiber on poles. You just change out the equipment at each end, which is a fraction of the cost of building new fiber.
Fiber is future proofing your community and your economic development future.
Wireless, by comparison, once the capacity of the existing radios is reached (which happens every three to four years), you have to replace pretty much everything. Do a fair thirty year life cycle comparison of fiber and wireless, and fiber is cheaper.
Infinera just announced that they have been able to push eight terabits of data across 800 kilometers of fiber, and they expect to be able to do that across 2,500 kilometers of fiber in the near future.
Fiber is a good investment.
