Presentation Transcript

  1. ECE 135 – Group 3 Presentation 4 Bryan Chavez with Pat Cleary & Kevin Parker February 10th, 2005

  2. Work Summary • Further Research into VCSELs • Researched ROSA Solutions in place of PDs • Four Corners Analysis for multiple candidate VCSELs • Contact vendors • Further Optical Link Budgeting • Test and Build Tx Board

  3. GANTT Chart

  4. Background Work for Four Corners and Optical Link Budget • Eye safe limit → Pmax = 1 mW • From the 802.3 standard → extinction ratio = 9dB • Thus we see that Pmin = Pmax *10^(-9/10) • Pmin = .12589 mW • Maximum Link Power Budget Loss at Rx from 802.3 Standard = 7.5 dB

  5. VCSEL Four Corner Analysis (A) HFE439x-521

  6. VCSEL Four Corner Analysis (B) TO - 46

  7. VCSEL Four Corner Summary

  8. ROSA Datasheet

  9. Draft Optical Link Budget

  10. Tx Board Construction

  11. Tx Board Performance • 0 dB Attenuation • BER: < 10^-9 • 1 Minute Duration

  12. Tx Board Performance • 10 dB Attenuation • BER: < 10^-9 • 1 Minute Duration

  13. Tx Board Performance • 20 dB Attenuation • BER: < 2x10^-7 • 1 Minute Duration

  14. Tx Board Performance • 30 dB Attenuation • BER: NO SIGNAL • 1 Minute Duration
