Presenter: Kenny Haulk

2 This Week’s Highlights Tested Receiver with attenuation and shielding Measured power output from GDS1250 TX and our own VCSEL Alignment tolerance tests Loopback tests with attenuation and shielding Start work on final paper

3 Receiver Tests with Attenuation and Shielding RX w/o shield at 5dBRX w/ shield at 5dB

4 Receiver Tests with Attenuation and Shielding (continued) RX at 10dB attenuation TX off

5 Power output from lasers Typical power output from the GDS1250 TX is 0.364mW With the 5dB attenuator mW (with the adjustment: mW) Max power output from our laser is almost 2mW! Adjusted output to around 1mW (eyesafe)

6 Eyesafe TX test TX at 0dBTX at 5dB

7 Alignment Tolerance Setup

8 Alignment Tolerance Results Region where we get acceptable results is basically circular Although, we may have estimated the center wrong Able to get a good eye, at center, up to 820um away

9 Alignment Tolerance Results 1=10um

10 Loopback Attenuation Tests with Shielding 5dB w/o shielding 5dB with shielding No optical input

11 Loopback Attenuation Tests with Shielding (continued) 10dB w/o shielding 10dB with shielding 15dB with shielding

12 GANTT Chart

13 Plans for the Coming Week Attempt to clean up loopback results Complete the final paper
