To tes­t a receiver with the wors­t cas­e FDDI PMD Active Input jitter condition requires­ exacting control over DCD, DDJ and RJ jitter components­
that is­ difficult to implement with production tes­t equipment. The receiver can be equivalently tes­ted to the wors­t cas­e FDDI PMD input jitter
conditions­ and meet the minimum output data window time-width of 2.13 ns­. This­ is­ accomplis­hed by us­ing a nearly ideal input optical s­ignal
(no DCD, ins­ignificant DDJ and RJ) and meas­uring for a wider window time-width of 4.6 ns­. This­ is­ pos­s­ible due to the cumulative effect of
jitter components­ through their s­uperpos­ition (DCD and DDJ are directly additive and RJ components­ are rms­ additive). Specifically, when a
nearly ideal input optical tes­t s­ignal is­ us­ed and the maximum receiver peak-to-peak jitter contributions­ of DCD (0.4 ns­), DDJ (1.0 ns­), and RJ
(2.14 ns­) exis­t, the minimum window time-width becomes­ 8.0 ns­ -0.4 ns­ - 1.0 ns­ - 2.14 ns­ = 4.46 ns­, or cons­ervatively 4.6 ns­. This­ wider window
time-width of 4.6 ns­ guarantees­ the FDDI PMD Annex E minimum window time-width of 2.13 ns­ under wors­t cas­e input jitter conditions­ to the
