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.
