• Port-density and spectral efficiency are factor 2.5 better for Metro 100G compared to 10G

• Break-even for 100G Metro is at ~ 6-7 x 10G

• 17-TWRS spans:• Average length and loss of 88km and 20dB respectively.

• SSMF slope-matched DCF module every 4 spans.

• EDFA only amplification.

Transmission Set-Up

The combination of the fiber type and the type of the neighboring channels represents the worst case scenario in today’s networks for 100G channels

• 80 WDM carriers spanning the full C-band.• 4 x 28G Duobinary subcarriers• 76 x 10G OOK.

• 100G super channel in the 1537 Wavelength band.

• ADVA Optical Networking offers a low-cost, high-performance 100Gb/s solution: • This solution is based on using 4x28Gb/s Duobinary carriers with direct-

detection.

• The high tolerance of this 100G solution to linear impairments has been confirmed• OSNR requirements that are similar to those of 100G coherent channels• A dispersion tolerance of +500 ps/nm• Negative penalty from the cascade of ROADMs

• The transmission of a 4x28G super-channel is demonstrated over one of the most challenging link configurations for 100G channel upgrades:• Transmission over 1500-km of TWRS fiber in the 1530nm regime.• 76x10G OOK channels co-propagated with the 100G channel.

Conclusions

Compared to the coherent 100G solution this solution trades off spectral-efficiency for lower cost, lower power consumption, lower

latency and a significantly higher tolerance to nonlinear effects
