Notes:
1. An OMA of 49 W is approximately equal to an average power of –15 dBm, and the OMA typical of 16 W is approximately equal to an average
2. An OMA of 31 is approximately equal to an average power of –17 dBm assuming an Extinction Ratio of 9 dB.
3. 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
4. 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
5. These average power values are specified with an Extinction Ratio of 9 dB. The loss of Signal circuitry responds to OMA (peak to peak) power,
power of –20 dBm, assuming an Extinction Ratio of 9 dB. Sensitivity measurements are made at eye center with a BER = 10E–12.
component min. (at TX) is 40 ps.
