Notes:
1. Input Optical Modulation Amplitude (commonly known as sensitivity) requires a valid 8B/10B encoded input.
2. An OMA of 61 W is approximately equal to an average power of –14 dBm, avg with an Extinction Ratio of 9 dB.
3. An OMA of 49 W is approximately equal to an average power of –15 dBm, avg with an Extinction Ratio of 9 dB.
4. An OMA of 31 W is approximately equal to an average power of –17 dBm, avg with an Extinction Ratio of 9 dB.
5. 4.25 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 1.67 dB for 50 m fiber and 2.14 dB for 62.5 m fiber. Stressed receiver DCD
component min. (at TX) is 20 ps.
6. 2.125 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 1.26 dB for 50 m fiber and 2.03 dB for 62.5 m fiber. Stressed receiver DCD
component min. (at TX) is 40 ps.
7. 1.0625 Gb/s stressed receiver vertical eye closure penalty (ISI) min. is 0.96 dB for 50 m fiber and 2.18 dB for 62.5 m fiber. Stressed receiver
DCD component min. (at TX) is 80 ps.
8. These average power values are specified with an Extinction Ratio of 9 dB. The loss of signal circuitry responds to valid 8B/10B encoded peak
to peak input optical power, not average power.
