Since silkroad is private, I've had to wonder what benefit I could possibly get in following this thread. For me, the thread has turned into a fantastic incubator of ideas other than Silkroad. For example, I seem to recall finding out about SDLI on this thread and making little money off the tip.

No promoter of silkroad has been able to humble himself sufficiently to explain how the optical modulation scheme works. That is unhealthy!

However, I am looking forward to the day when someone can explain just what electronics technology (mm Wave mixers maybe? Pockels cells?) can consolidate enough data streams to drive a single optical modulator with 200Gbit bandwidth. If the 200 GBit data rate were a single serial data stream, the wavelength would be 3 x 10^10 cm/sec / 2x10^11/sec = 0.15mm (0.006"). It would take a very small microelectronic structure just to transmit and manipulate the signal for modulation.

To me DWDM has one advantage in that I can conceptually agree with combining a number of streams at 2.5GB ( as electrical signals they are: 3 x 10^10 cm/sec / 2.5x10^9 /sec = 25mm wavelength) optically because the technology for modulation is fathomable.

If such an explanation is way beyond the scope of this thread, then maybe someone has a bibliography that would better explain how the physics work.
