The ANSI T1E1.2 committee has designated the possibility of defining an eye pattern mask for the transmitter optical output as an item for
further study. Avago will incorporate this requirement into the specifications for these products if it is defined. The HFBR-59XXL products
typically comply with the template requirements of CCITT (now ITU-T) G.957 Section 3.2.5, Figure 5 for the STM- 1 rate, excluding the optical
receiver filter normally associated with single mode fiber measurements which is the likely source for the ANSI T1E1.2 committee to follow in
this matter.

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 Avago
receiver.
