Cost comparison
•
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

3. Transmission Set-Up
• 17-TWRS spans:
•
Average length and loss of 88km and 20dB respectively.
• SSMF slope-matched DCF module every 4 spans.
• EDFA only amplification.
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

4. DWDM Spectrum
• 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.

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