Group 2 - Project Update April 1, 2004 Tyler Helble
Progress Report Finalized TX/RX Board Design Ordered TX/RX Boards from Express PCB Ordered Passives, VCSEL, and PD Soldered components Tested TX/RX Aggressive and Non- Aggressive Revised Gantt Chart Published Midterm Report
TX/RX Board Design
Aggressive Design Standard Design
PCB Board – Solder Side
PCB Board – Ground Plane
PCB Board – VCSEL, PD, Passives PD Hamamatsu S5973 VCSEL Lasermate Hamamatsu S5973
PCB Board – Soldered Components PD VCSEL
TX/RX Test Results Initial Tests Revealed no power to TX chips. Board was getting hot. Found solder link between power and ground, etched it out. Retested and obtained decent eye results using the probe. (VCSEL not attached yet)
TX/RX Test Results – using probe
TX/RX Test Results Received visible eye on Agilent osciliscope.
TX/RX Test Results RX board powered up, chips receiving power Aligned fiber using XYZ stage in lab No signal from the SMA connector Tried to detect signal with probe, no luck
TX/RX Test Results Using the XYZ Stage to align The fiber and PD
Future Plans Solder VCSEL and test today Test PD separately to double check pins/light detection Pray
