"Combining the two accomplishments would produce 160 Gbits/sec across 1022 separate wavelengths--a total capacity of more than 163 Tbits/sec. While such a combination is impossible today, the confluence of such work appears to be where optical networks are headed in the future."

Dave, granted, the author states LU's claim that this is not achievable today. Reaching such rates would seem to violate the theoretical limits of the now-usable optical spectrum. To reach such data throughput rates it would seem to me that they would need to begin employing analog modulation schemes with higher bit-to-hertz ratios than that which is achievable through straight non-return to zero (NRZ) digital schemes, which is now the norm.

But they don't say that. I've predicted this before elsewhere on these boards, however, that at some point future breakthroughs in long haul fiber gain techniques will take place through analog QAM-like techniques on opaque networks which mimic the traditional platform topologies of the past, and possibly through muli-level CDMA transport in newer 'transparent' ones which truly mimic unencumbered ethers.

The Yipes Ehternet and the Tunable Laser articles which preceded this one were good finds, too. It seems like others are fast at work designing our ftth platform for us. Thanks. Frank
