Channel Parameter Estimation for Polarization Diverse Coherent Receivers
J. C. Geyer,Fabian N. Hauske,C.R.S. Fludger,T. Duthel,C. Schulien,M. Kuschnerov,K. Piyawanno,D. van den Borne,E.-D. Schmidt,Bernhard Spinnler,H. de Waardt,Berthold Lankl,Bernhard Schmauss +12 more
TL;DR: In this paper, a robust in-service estimation of fiber channel parameters from equalizer parameters of a polarization diverse coherent receiver is presented, which is derived from a theoretical fiber channel model.
Proceedings ArticleDOI
Carrier phase estimation for coherent equalization of 43-Gb/s POLMUX-NRZ-DQPSK transmission with 10.7-Gb/s NRZ neighbours
D. van den Borne,C.R.S. Fludger,T. Duthel,T. Wuth,E.-D. Schmidt,C. Schulien,Erich Gottwald,GD Giok-Djan Khoe,H. de Waardt +8 more
TL;DR: In this paper, the influence of 10.7-Gb/s neighbors on 43-g/s polarization-multiplexed NRZ-DQPSK transmission combined with digital coherent equalization is analyzed.
Proceedings ArticleDOI
Optimizing power consumption of a coherent DSP for metro and data center interconnects
TL;DR: Several options for reducing power consumption of DSP used for coherent interfaces are discussed, put in perspective with the needs of metro and data center interconnects for an overall optimized solution.
Proceedings ArticleDOI
Optical Performance Monitoring from FIR Filter Coefficients in Coherent Receivers
Fabian N. Hauske,J. C. Geyer,M. Kuschnerov,K. Piyawanno,T. Duthel,C.R.S. Fludger,D. van den Borne,E.-D. Schmidt,Bernhard Spinnler,H. de Waardt,Berthold Lankl +10 more
TL;DR: In this paper, a robust and precise optical performance monitoring technique from FIR filter coefficients in coherent receivers with digital equalization is presented, where residual chromatic dispersion, DGD and OSNR are simultaneously estimated from measured 111 Gbit/s data.
Proceedings ArticleDOI
Joint-polarization carrier phase estimation for XPM-limited coherent polarization-multiplexed QPSK transmission with OOK-neighbors
M. Kuschnerov,D. van den Borne,K. Piyawanno,Fabian N. Hauske,C.R.S. Fludger,T. Duthel,T. Wuth,J. C. Geyer,C. Schulien,Bernhard Spinnler,E.-D. Schmidt,Berthold Lankl +11 more
TL;DR: In this paper, joint polarization carrier phase estimation for XPM-limited channels with significant improvements over standard methods was demonstrated on measurements of 43 Gb/s NRZ-CP-QPSK with 10.7 Gb /s OOK neighbors.
