Following up on my previous post, let’s take a look at the pure 100G wavelength option. Right now they can do pure 40G waves and they think they can use what they learned getting to 40G to get to 100G on a single wavelength. From a network design point of view, this is quite desirable because everything new is inside the black box, all you have to do is buy the new black boxes. However, it has taken 40G some 8 years to become affordable relative to 10G, and even then just barely. If one is going to scale that solution by tens and hundreds without reducing prices at the same rate, it becomes unaffordable quickly.
- fiber-poor carriers can increase capacity forever
- the paradigm doesn’t change, network design looks the same as you scale
- each jump requires a technological leap of faith
- just because you figure out *how* doesn’t mean you can do it affordably in the same time frame.
- There are no real losers because the basic infrastructure that everyone has will still be just fine.
- The winners are those with limited fiber, because that limit no longer matters – they can always keep up. Cogent, for instance, is a big fan of this solution. So are VZ and AT&T, who have mostly older fiber and would have to dig in order to install new stuff at some point.
- If it requires new breeds of optical fiber to follow this route, then the eventual winners are those with empty conduits – Level 3 and Qwest.
