Yes, they put the demo on Youtube – which basically consists of a hardware engineer named Dave pointing at and naming every cool device in his lab at Nortel, then hitting one with a hammer to show that it still works afterward.
He reminds me of someone from college, betchya nobody else is allowed to touch that hammer…
I think we can safely say that 100G is coming, it seems like the technical hurdles have been overcome across the board. The question now is making it economical and building a production device. What’s it going to cost?

Nortel using a pre-standard 100GbE client signal instead of 10×10GbE is one difference compared to the Ciena demo but probably more interesting is the different DWDM line interfaces. While both use dual polarizations and (D)QPSK modulation, Nortel uses coherent instead of differential detection which makes the solution more tolerant to PMD and other distortions. In addition, Nortel actually uses two wavelengths within one 50 GHz slot to transmit 112 Gbps.
