Semester Summary Started off clueless Got hope after testing the practice board Worked on OLB Designed the transceiver and did the layout Tested and debugged It works!!! 11/18/2018

From laser driver specs Optical Link Budget From graph From Standard From Standard From schematics From laser driver specs 11/18/2018

Optical Link Budget 11/18/2018

Schematics 11/18/2018

Design Layout 11/18/2018

Test Results – Baseline Rx PRBS7 11/18/2018

Test Results – Baseline Tx PRBS7 11/18/2018

Test Results – Loopback PRBS7 11/18/2018

Test Results – Attenuated Tx PRBS7 – 5dB PRBS7 – 10dB 11/18/2018

Test Results – Attenuated Rx PRBS7 – 5dB PRBS7 – 10dB 11/18/2018

Test Results – Att. Loopback PRBS7 – 5dB Unshielded PRBS7 – 5dB Shielded 11/18/2018

Test Results – Att. Loopback D21.5 – 10dB Shielded 11/18/2018

Test Results – Alignment Rx PRBS7 11/18/2018

Test Results – Algn. Loopback PRBS7 11/18/2018

Test Results – Algn. Tolerance PRBS7 In x-direction ~ 0.5 μm tolerance Thanks to Group 2 for letting us borrow your PD! In y-direction ~ 0.75 μm tolerance In z-direction ~ 2 μm tolerance 11/18/2018

Monetary Budget 11/18/2018

Bill of Materials 11/18/2018

Final Gantt Chart 11/18/2018

Results Summary Baseline Rx, Tx, and Loopback successful Attenuation testing successful after discovery of fiber voodoo PRBS7 Loopback works for 5 dB, while D21.5 works until 10 dB attenuation Alignment testing cut short due to limited lab time 11/18/2018

Anticipated Progress for Week 17 HUH !! What progress ?? We done 11/18/2018
