Received Parts

Received all parts from DigiKey and Jameco

Received an excess of SMA connectors

All parts accounted for

Received PCB 3 PCBs arrived on time Immediate problem

Ground plane not connected to power connector’s ground

Oops! Problem rectified with an

alligator clip

Building Soldered a transmitter and receiver pair

Short was discovered and unaccounted for Soldered second transmitter

Testing

Bypassed the ground problem with alligator clip

Discovered that the laser is not lasingUsed digital camera to confirm, as well

as red Rx LOS light on GBIC Pattern Generator

Continued testing and debugging will be required to determine the problem

Midterm Report

Draft nearly completedWill be posted to website by 5:00pm

tomorrow

Upcoming Week

Finish ReportContinue Testing and Debugging

in order to determine the problem(s)

Modify schematics and board design accordingly
