Progress Report • Tested and verified functioning Rx • Tested and verified functioning Tx • Updated our board design • Ordered additional parts • Ordered and received second board
Rx Testing • Test with input from pattern generator • Very good eye pattern 40dB Attenuation 70dB Attenuation
Tx Testing - Conservative 0dB/205ohm 0dB/515ohm
Tx Testing - Aggressive 0dB/810ohm
GabE Board Design 2.0 • Fixed power connector • Changed orientation of VCSEL • Gave the ground plane around the Tx chip more space • Aggressive design strives to achieve LC spacing but violates many design rules
Upcoming Week • Build GabE Board Design 2.0 • Begin extensive testing of new design • Loopback tests • Attenuation
