15. Inter-channel Skew is defined for the condition of equal amplitude, zero ps skew input signals.
16. Rise and Fall Times are measured between the 20% and 80% levels using a 550 MHd square wave signal.
17. The Signal Detect output will change from logic “0” (Low) to “1” (High) within the specified assert time for a step transition in optical input
18. The Signal Detect output will change from logic “1” (High) to “0” (Low) within the specified de-assert time for a step transition in optical
19. Sensitivity is defined as the average input power with the worst case, minimum, Extinction Ratio necessary to produce a BER < 10
20. The stressed receiver sensitivity is measured using 2.6 dB Inter-Symbol Interference, ISI, (min), 30 ps Duty Cycle Dependent Deterministic
21. The stressed receiver eye opening is measured using 2.6 dB ISI (min), 30 ps DCD DJ (min), 6 dB ER (ER Penalty = 2.23 dB) and an average
22. Return loss is defined as the ratio, in dB, of the received optical power to the optical power reflected back down the fiber.
23. Signal Detect assertion requires all optical inputs to exhibit a minimum 6 dB Extinction Ratio at P
