Notes:
17. Receiver sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
18. Stressed receiver sensitivity is measured using the conformance test signal defined by IEEE 802.3, section 38.6.11. The conformance test
signal is conditioned by applying deterministic jitter and intersymbol interference.
19. The Receive Electrical 3 dB Upper Cutoff Frequency of the receiver is measured using the technique outlined in IEEE 802.3, section 38.6.11.
20. Return Loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.
21. With valid 8b/10b encoded data.
22. Time from rising edge of Tx_Disable to when modulated optical output falls below 10% of nominal.
23. Time from falling edge of Tx_Disable to when the modulated optical output rises above 90% of nominal.
24. Time from power on or falling edge of Tx_ Disable to when the modulated optical output rises above 90% of nominal.
25. Time Tx_Disable must be held high to disable transmitter. Measured from leading edge of Tx_Disable to when the modulated optical
output falls below 10% of nominal.
26. Time from SD deassert to SD assert.
27. Time from non-SD assert to SD deassert.
