Hi Jack, lu deals with channel spacing thus: "Conventionally, DWDM signals are separated by 50 GHz frequency spacing, but the 1,022-channel system operates at a record high density of 10 GHz channel spacing. Each channel occupies only 10 GHz of frequency bandwidth, making this an ultra-dense WDM transmitter." they sniff that "soliton technology is not as reliable as photonic and considerably more expensive". Geoff, do you have a view on the reliability of solitons? I don't have a view on reliability in real-world applications-as far as I know there are no soliton-based systems in use today. The Qtera and Corvis field trials are designed to answer these and other questions. I will say that I think we sill see soliton-based systems in general availability long before we see GA of DWDM systems using 10GHz channel spacing-I think that is an example of them kiddin' ya.
