• Deployment of a OUT-4 (100G) single alien wavelength
between São Paulo and Miami using Padtec transponders
– Distance: in the range of 10,000 km
– Modulation format DP-QPSK
– 50 GHz spacing
– Cromatic Dispersion Tolerance:
• Low : 45 ns/nm
• High :250 ns/nm
• LANautilus fiber pair, highly constrained submarine system
• 6 months testing regime - RNP, ANSP, FLR, Internet2
among others

• Meet all constraints without any change in the cable – operational
link
– Power and non linearity
• Non linear phase noise
– OSNR
– Pre FEC BER
• Upgrade without any penalty in the existing wavelengths
• Multivendor environment: Alcatel, Ciena and now Padtec
Challenges

Strengths
8 – © 2013 Internet2
• Padtec has a unique access to advanced 100 G DSP for coherent
detection
– Partnership and strategic investment with Clariphy
• Civcom and Padtec have been producing 100 G transceivers and
line cards for two year
– Deployed to T1 companies like Telefonica
– Deployed for regional operators like GVT
• Padtec made substantial investment in optical submarine business
– Optical regenerator with 6 amplifiers inside
– Depth higher than 8,000 m
– Sea trial in end of April/2014

• Two phases divided by segments:
– Phase 1
• Segment A: Fortaleza – Saint Croix
• Segment B: Rio – Fortaleza
• Segment C: Santos – Rio
– Phase 2: Miami – Saint Croix
• Longer segment will be analyzed first: Fortaleza – Saint Croix
– Transceivers modeling
– Link modeling
– Link simulation – VPI
– Laboratory tests: real network assembled at Padtec laboratories –
Campinas/Brazil
– Field trial
Steps of This Project

• Modeling concluded
– Transmitter and receiver
– Optical amplifiers
– Dispersion map
• Simulations of Segment A on the way – end of April
• Manufacturing of amplifiers for laboratory tests
– Only Segment A will be assembled in laboratory
• Next steps: simulation of Segment B and C
• Upgrade report for all segments
• Field trial in the beginning of 2015

Conclusion
11 – © 2013 Internet2
• Coherent technology is a breakthrough for system upgrade
• Padtec met key technologies for this project
– Coherent transceivers
– Coherent line cards
– DSP
– Optical amplification for ultra long distance system
• Modeling, simulation and experiment will be in advance to support
field trial
• Padtec has a huge background on optical transmission under
almost non linear regime
