  1. ECE 135. Opto-Electronics Design Project Spring 2006

  2. History of Offerings Spring 2004 Duke ECE 164.02   Electronics Design (14) Spring 2004 Duke ECE 164.02   Electronics Design (7) Spring 2003 Georgia Tech ECE 4006 C   Capstone Design Course (30) Fall 2002 Georgia Tech ECE 4006 B   Capstone Design Course (30) Spring 2002 Georgia Tech ECE 4006 C   Capstone Design Course (30)

  3. IEEE 802.3 Standards

  4. Final Gantt Chart

  5. Division of Labor

  6. Board Design • TX Schematic

  7. Board Design • RX Schematic

  8. Bill of Materials (BOM) * two Tx/Rx can be fabricated on one PCB board, prices based on 10,000 order aside from Maxim chips

  9. Gigabit Ethernet – Loop Back Test • Completed aggressive TxRx by adding SMA connectors • Test setup using XYZ stage • Note excessive fiber length due to VCSEL output

  10. Gigabit Ethernet – Loop Back Test • Looped Tx output into PD on aggressive Rx • 0dB attenuation • Stylish Goggles!

  11. Gigabit Ethernet – Loop Back Test • Scope set to 1 second persistence • 0db attenuation • 2db attenuation

  12. Gigabit Ethernet – Loop Back BER Test • 4db Attenuation BER of 0.2x10-10 • Signal lost at 5dB Attenuation • 0-3dB Attenuation BER of 0.0x10-10 (1 minute)

  13. Group Final Report

  15. Conclusion (cont’d) • Though Gbps Ethernet is important, that was not the core concept taught in the class (surprise?). • Learned how actual engineering works and for some it was a first taste in actual hands on experience in professional practice. • Even though this course was not lecture intensive, it is possibly one of the more important classes in ECE… We now understand why.

  16. Graduation (Party) Coming Soon…
