Notes:
1. An OMA of 49 uW is approximately equal to an average power of -15dBm, and the OMA typical of 16 uW 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 μm fiber and 2.03 dB for 62.5 μm fiber. Stressed receiver DCD
4. 1.0625 Gb/s Stressed receiver vertical eye closure penalty (ISI) min. is 0.96 dB for 50 μm fiber and 2.18 dB for 62.5 μm fiber. Stressed receiver DCD
5. These average power values are specified with an Extinction Ratio of 9 dB. The Signal Detect circuitry responds to OMA (peak-to-peak) power, not
6. Please refer to the AFBR-5921ALZ Characterization Report for typical values.
Table 10. Transceiver Timing Characteristics
(T
Notes:
1. Time from rising edge of TX Disable to when the optical output falls below 10% of nominal.
2. Time from falling edge of TX Disable to when the modulated optical output rises above 90% of nominal.
3. From power on or negation of TX Fault using TX Disable.
4. Time TX Disable must be held high to reset TX Fault.
5. Time from optical signal loss to SD Assert. See transceiver timing diagrams.
6. Time from optical signal recovery to SD De-assert. See transceiver timing diagrams.
