  1. Metrics and Methods for TTC-PON System Characterization (An overview) Dimitrios-MariosKolotouros PH-ESE-BE

  2. Setup ** * * *Generators 1 & 2: Stanford Research Systems, CG635 **Generators 3: Agilent, 81130A D.M. Kolotouros, S. Baron PH-ESE-BE

  3. Downstream • BER • Specifications : 28.5dB • Measured : 30.8dB • Safe split ratio : 1:64 • Margin : 6dB D.M. Kolotouros, S. Baron PH-ESE-BE

  4. Downstream • Payload • Trigger : 1/25ns • Trigger type (T and F) : 630Mbps • Broadcast data : 590.8Mbps • Unicast data : 9.23Mbps D.M. Kolotouros, S. Baron PH-ESE-BE

  5. Downstream • Jitter of the recovered clock D.M. Kolotouros, S. Baron PH-ESE-BE

  6. Latency (Downstream & Upstram) D.M. Kolotouros, S. Baron PH-ESE-BE

  7. Latency (Downstream & Upstram) D.M. Kolotouros, S. Baron PH-ESE-BE

  8. Upstream • Custom protocol D.M. Kolotouros, S. Baron PH-ESE-BE

  9. Upstream • Reference BBER and PLR • CID : 3200 bits • Δφ : 0⁰ • Preamble : 1120 bits • Comma length : 16 bits • Data length : 2032 bits D.M. Kolotouros, S. Baron PH-ESE-BE

  10. Upstream • Effect of the CID length ONU1 O-CDR BBER ONU1 N-CDR BBER ONU1 O-CDR PLR ONU1 N-CDR PLR D.M. Kolotouros, S. Baron PH-ESE-BE

  11. Upstream • Effect of the Dynamic Range α=3dB ONU1 ONU2 D.M. Kolotouros, S. Baron PH-ESE-BE

  12. Upstream • Effect of the Dynamic Range ONU2 O-CDR BBER ONU2 N-CDR BBER ONU2 O-CDR PLR ONU2 N-CDR PLR D.M. Kolotouros, S. Baron PH-ESE-BE

  13. Upstream • Effect of the Preamble length ONU1 O-CDR BBER ONU1 N-CDR BBER ONU1 O-CDR PLR ONU1 N-CDR PLR D.M. Kolotouros, S. Baron PH-ESE-BE

  14. Upstream • Effect of Phase step ONU1 ONU2 Δφ= 0o Δφ= 150o Δφ= 300o D.M. Kolotouros, S. Baron PH-ESE-BE

  15. Upstream • Effect of Phase step ONU2 O-CDR BBER ONU2 N-CDR BBER ONU2 O-CDR PLR ONU2 N-CDR PLR D.M. Kolotouros, S. Baron PH-ESE-BE
