Notes:

1. Transmitter consists of 4 lasers operating at 25.78Gb/s each.

2. Minimum value is informative.

3. Hit ratio 5x10^-5.

4. Receiver consists of 4 photodetectors operating at 25.78Gb/s each.

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

6. SRS is measured with vertical eye closure penalty of 1.8 dB max, J2 of 0.30 UI, and J9 of 0.47 UI.

7. Power value and power accuracy are with all channels on..

Note: When using this 100G QSFP28 ER4 transceiver in short-distance transmission, please add a LC fiber attenuator (≥9dB) to avoid receiver damage and overload.
