10 Consortuim Confidential 43Gb/s RZ-DQPSK (WP6 prototypes) Motivation Why 43 Gb/s RZ-DQPSK?  Suitable for long haul transmission in typical terrestrial networks (80 km spans with no Raman-amplification)  Allows upgrade of existing 10 Gb/s systems w/o change of infrastructure  Less sensitive to chromatic dispersion and non-linearities than conventional modulation formats as e.g. NRZ, RZ at 40 Gb/s  Less sensitive to PMD than other modulation formats as e.g. Optical Duobinary (ODB) Objectives:  Performance verification  Investigation of impact of nonlinear phase noise, due to Gordon-Mollenauer noise and cross-phase modulation (XPM)

11 Consortuim Confidential 43Gb/s RZ-DQPSK Experiments System set-up  9 amplifiers, 8 fibre spans (total 660km)  With 10 Gb/s MUX/DMUX  Dispersion map includes pre/under- compensation  Noise loading to adjust OSNR  Includes 13 dummy channels  Up to four 10 Gb/s NRZ-modulated neighbour channels (spacing: 50 & 100 GHz)

12 Consortuim Confidential 43Gb/s RZ-DQPSK Experiments Results BtB:  careful optimisation of the whole back- to-back setup, let to our knowledge to best back-to-back curve reported so far DWDM system tests:  Influence of OOK neighbours verified  System margin from EFEC limit in all cases > 3dB (Q=10dB)

14 Consortuim Confidential GMPLS performance and scalability Motivation  Investigate the performance and the scalability of an ASON/GMPLS optical control plane with respect to path provisioning

15 Consortuim Confidential GMPLS performance and scalability Number of nodes and LSA flooding impact  Effect of the number of nodes in path on the path setup time  Effect of LSA (Link State Advertisement) flooding on the path setup time

16 Consortuim Confidential GMPLS performance and scalability Scalability and LSA Threshold tuning analysis  LSA percentage: when the available link bandwidth changes by more that  %, an LSA flooding is performed (LSA  %)  The mean setup time decreases exponentially for LSA 0% till LSA 20%. After that, the decrease in nearly constant  Path setup time nearly linear with the number of the nodes taking part in the route

17 Consortuim Confidential Experimental GMPLS fault management for OCh transport ring networks Motivation  Propose enhanced GMPLS recovery schemes for OCh fault management in Rings when the link failure also affects to the control channel  Recovery of the control plane after a link failure Loss of LightOptical signal recovery Optical Protection delay ~ 100 ms First Ping without reply Each 100ms a ping from OCC1 to OCC3 is sent First Response after failure IP/ Control Restoration delay ~ 2100 ms OCC 1 OCC 2 OCC 3 Trans.
