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 I 0.3Gb/s each.
5.Minimum value is informative, equals min TxOMA with infinite ER and max. channel insertion loss.
