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 ad-
ditive). 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
