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).
Ah, so it's actually 4 different wavelengths within the ITU-grid alottment of one single 10G wave?
Can 10G optical amplifiers be used?Yepp..
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? -- Mikael Abrahamsson email: swmike () swm pp se
