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 XYZStage to align The fiber and PD

Future Plans

Solder VCSEL and test today Test PD separately to double check pins/light
