Flexible Optic Fiber Promises Cheaper Last Mile
bn0p writes "Ars Technica has an article on a Korean company that has developed a low-cost, flexible, plastic optical fiber that could bring cheaper 2.5 Gbps connections to homes and apartments. While not as fast as glass fiber, it is significantly faster than copper. In related news, Corning recently announced a flexible glass fiber that can be bent repeatedly without losing signal strength. The Corning fiber incorporates nanostructures in the cladding of the fiber that act as 'light guardrails' to keep the light in the fiber. The glass fiber could be as much as four times faster than plastic fiber. Neither fiber is available commercially yet, but both should help with the last mile problem when they are deployed."
If you don't have other reasons to dig trenches etc, then wireless is typically far cheaper because the installation costs are zero.
Engineering is the art of compromise.
Not in the United States anyway, our "last mile problem" has a lot more to do with entrenched telecom and cable companies with regional monopolies than any sort of fiber bendiness.
I don't think the cost of the actual cable will change the equation very much. I've been out of it for more than ten years, but even then you could get fiber for less than $1/foot - I assume it's even cheaper now. I have to believe most of the cost lies in planning, getting permits, and digging trenches.
What I don't get is why we seemingly refuse to invest for the long-term in the United States. Sure, some companies do, generally the smarter ones. But when it comes to public infrastructure, politicians haven't found a way to inform the public that by spending 2x as much now, we're saving 20x as much over the next n years.
I know that technology evolves at a rapid rate, but if we invest more money now and use the same amount of energy* now (compared to doing investing less money and the same amount of energy), then we can use the energy that's left over from not having to double our efforts next year for other causes.
*energy here is refering to human capital.
