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

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
