Eric,
The total number of calls is not astounding in itself, given that they are using four fiber pairs... they've pumped the lines to full bore to their current capabilities.
However, I think that your question concerning WDM and DWDM is the point here, and it is reflective of the current confusion caused by marketecturists. G. Gilder has a good time with this one. The point being, why call it dense? Dense compared to what? It's a term that will outgrow itself very quickly.
WDM is WDM. If further descriptors must be used, then perhaps WDM-4 or WDM-96, and eventually WDM 1024, and higher, etc., should be used.
Apparently, the British have not caught on yet to this new way to obfuscate issues. In answer to your question, then, they're all WDMs of one quantity or another. HTH,
Regards, Frank C. |
