Right Choice of the 3rd 40G Coherent Tech.
3dB of incensement from Coherent tech. than non-coherent tech. that is, 2 times performance.
| 11.5GBaud, 1 carrier |
11.5G Baud, 2 carriers Better non-linear performance than QPSK Mature industrial chain |
22.4G Baud, 1 carrier Better non-linear performanceSame industrial chain as 100G coherent |

ePDM-BPSK, That’s It
PBS=Polarization Beam Splitter PBC=Polarization Beam Combiner
40G@1 λ
90ps DGD tolerance at 1dB penalty(Operation over very old fibre)
±60,000 ps/nm chromatic dispersion tolerance at 1dB penalty
Excellent nonlinear performance
Smoothly upgraded from today’s 10G/40G WDM
80ch x40G transmission distance: >2000km – same as 10G ULH
Beta version for trial: 2011Q3
