Power output from lasers
• Typical power output from the GDS1250 TX is 0.364mW
• With the 5dB attenuator 0.0067mW (with the adjustment: 0.0605mW)
• Max power output from our laser is almost 2mW!
• Adjusted output to around 1mW (eyesafe)

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
