In last month's Nature, Photonics reported a nice combination of an old optical telecommunications trick with new photonic technologies. in doing so the researchers who performed the work have opened the door to using these new devices in standard telecommunications networks.

Optical communications achieves very high data rates through a combination of fast modulation of a single channel (around 10Gbps) and running multiple channels down the same fiber. Each channel is a slightly different wavelength (color), so the maximum bandwidth depends on how closely these channels can be spaced. The minimum channel spacing is set by the ability to separate light of different wavelengths.

I thought they already did this, Don't they use another way of seperating channels by the method in which Satalite works as well? Various bits of information within a single wavelength could produce a set of subchannels?

Reguardless, more speed using the same pipes is always a good thing.
