Optical Transmission at >/= 100Gbps Rates
John, this goes back to the recent announcements concerning Internet2's "upgrade" to 100 Gbps, as outlined above at: tinyurl.com .
Earlier today I came across, quite by accident, the following account of Oki Data's 160 Gbps experiment while snooping for information about a polarization mode dispersion and chromatic dispersion (PMD/CD) mitigation startup, and it caused me to wonder what all the celebration over I2's move to a 100 Gbps rate was all about. Consider, in the case of I2, there were ten (10) 10Gbps channels "in the middle" put through an inverse multiplexer at each end in order to achieve a single rate of 100 Gbps "at the ends." And, in the Oki case an even higher optical data signaling rate of 160 Gbps was used "in the middle" without resorting to inverse multiplexing of multiple wavelengths at the ends. Your thoughts? Anyone? Tom Swift, have you anything to say about this that you'd like to share? I may simply be missing a very basic point, somewhere along the line. Here's the Oki announcement, accompanied by a photo, below, of the optical TDM device that was used almost a year ago, taken from a March 2006 article in Lightwave Magazine:

Oki Electric attains 160-Gbit/sec data transmission
March 16, 2006 Tokyo, Japan -- Oki Electric Industry announced that it has achieved experimental 160-Gbit/sec data transmission over a distance of 635 km, in a field trial conducted as part of a project consigned by Japan's National Institute of Information and Communications Technology (NICT).
