Transcript Background to Sensitivity Motions

• Background to Sensitivity Motions:
– Specific Numbers in Motions Assume Elimination of Dynamic Adaptation
Penalty Test and associated 0.5 dB Dynamic Penalty as well as Reduction of
Connector Loss from 2.0 to 1.5 dB in Link Budget. Increases Both Static
Stressed Test and Simple Receiver Test Required Max. OMA by 1.0 dB.

• Motion:
– Adopt Following Parameters for Static Stressed Sensitivity Test in D1.0
in Table 68-4
» Maximum OMA of –6.6 dBm (TBC)
» Clock Sinusoidal Jitter Frequency of 40 MHz
» Clock Sinusoidal Jitter Amplitude of 0.1 UI
– Remove References to Sinusoidal Interferer Parameters in Table 68-4
– Add Line in Table 68-4 for Optical Signal to Noise Ratio of Stressed
Sensitivity Test Compliance Signal with Value TBD.

• Motion:
– For Draft D1.0 :
» Adopt 52.9.5 For OMA Measurement at TP2
» Define OMA Measurement of TP3 Compliance Signal With Same
Method But With Recommended Square Wave Test Pattern with
10 ‘1’s and 10 ‘0’s.
» Define OSNR Measurement of TP3 Compliance Signal With Same
10 bit Square Wave and Histogram Measurements of 0 and 1
Levels To Fit Gaussian Noise Distributions.

• Motion:
– Pursue Development of a Set of 3 ISI Impairments For the Stressed
Receiver Sensitivity Test Consisting of Pre-Cursor, Post-Cursor and Quasi
Symmetrical Impulse Responses.
– Define ISI Impairments Using A Set of Up to 5 Impulse Peaks with Single
Uniform Time Spacing, an Effective Pulse Response, and a Maximum PSR
Metric From popescu_1_0904 For The Difference Between the Compliance
Signal and The Defined ISI Impairments.
– Not Use PIE-L Metrics in Evaluating Suitability of ISI Impairments in the
Stressed and Simple Sensitivity Tests
– To Assume Transmitter Pulse Responses of Not Less Than 47 ps Rise/Fall
Times in Combination with The Channel Model in the Development of the
TP3 Compliance Signal.
