1. ECE 4006B Fall, 2002, Group 3, Man Le Progress Report Period (November 15-21, 2002) Finished alignment tolerance testing with Rx board (S7911 and PDT- A85A30) Life is back in our Tx board - Solved problems and changed all components as stated last week (replaced Rmod, lowered VCSEL…) - Soldered new Tx board - Result: good open eyes (conn VCSEL) Thanks to group 1 for spec sheet on unconnectorized VCSEL, tips on alignment tolerance testing on Tx board, and loaning us a Rx board Need to trade unconn VCSEL for conn PD (if interested see us) Progress: Continue Working on alignment tolerance testing on Tx board Focus on the final paper Next Week:
