What is the range of this, how often do you need to amplify and regen the
40G signal compared to 10G?
You can run the same distance as you do with your 10G system.
It;s mostly driven by dispersion, crosstalk and snr if you have many
amps. Milage varies with span design, but is not much different than
10G (as the symbol speed is till 10G).
Can 10G optical amplifiers be used?
Yepp..

Ah, so it's actually 4 different wavelengths within the ITU-grid
alottment of one single 10G wave?

How does the fact that you need to amplify four times the photons in the
same wavelength space affect things? Just needs to be taken into
consideration when calculating the amount/number of
amplification/amplifiers?
Is this something in production or alpha/beta test with the DWDM
manufacturer?
I'm curious here, don't photons cause a lot of
reflective jitter because of their large size ??
