36. Optical Networking (Cognitive Amplifier)
BER
• Cognitive process based on:
• Adaptative process based on optical amplifier operation points discrete performance caracterization;
• Then a machine learning process based on neural networks is used for extrapolation of operating
region points and cognitive process feedback supported by channels bit error rate (BER);
• Goal: channels performance maximization (lowest noise figure with good flatness);
• Result: 400% (6 dB) QoS enhancement;

37. Adaptable Flexible Transponder
• Adaptive process:
• The QoS parameter (OSNR) is obtained through monitoring application, than in case of minimum threshold
point achieved, the transmitter modulation format is reconfigured to enhance performance;
• Goal: Keeping Tx/Rx rate even under drastic network conditions allied to spectral efficiency maximization;
• Result: Error free transmission for a 224Gbps signal under 22 dB OSNR degradation
• Reconfiguration:224Gbps (2 carriers, 28Gbaud x4 symbols) 16QAM;
224Gbps (4 carriers, 28Gbaud x2 symbols) DP-QPSK;

39. Final Remarks
 The main goal of this workshop is incentivate Brazil-UK
cooperation in High Speed Networks area
 From photonics to microelectronic devices, passing trough
physical layer reaching network controllers, both sides have a
stablished ecosystem to contribute!!!
 Joint participation in EU/Brazil calls is a good starting point!!!!
 Let’s start small, think big and move fast!!!!
