Notes:

1.Transmitter consists of 4 lasers operating at 10.3Gb/s each.

2.Minimum value is informative.

3.RIN is scaled by 10*log(10/4) to maintain SNR outside of transmitter.

4.Receiver consists of 4 photodetectors operating at 10.3Gb/s each.

5.Minimum value is informative, equals min TxOMA with infinite ER and max channel insertion loss.
