1) _{Fibre Channel PI Standard. Typical OMA values based on –6 dBm launched power (average) and 15 dB}
extinction ratio.
2) _{Into multimode fiber, 62.5 µm or 50 µm diameter.}
3) _{Deterministic Jitter is that jitter measured by a bathtub scan, using a 2}7_{–1 NRZ PRBS, and extrapolating to}
1 BER.
4) _{Total Jitter is that jitter measured by a bathtub scan, using a 2}7_{–1 NRZ PRBS, and extrapolating to 1x10}–12 _BER.
5) _{Jitter (pk-pk) is measured using a 2}7_{–1 NRZ PRBS and a Digital Communications Analyzer.}
6) _{Values are 20% - 80%. Measured at nominal data rate, unfiltered, using an O/E plug-in with a bandwidth of}
2.85 GHz or higher. Complies with FC 1x, FC 2x and Gigabit Ethernet eye mask when filtered.
7) _{Receiver characteristics are measured with a worst case reference laser.}
8) _{Fibre Channel PI Standard.}
9) _{Average optical power at which the BER is 1x10}–12_{. Measured with a 2}7_{–1 NRZ PRBS and ER = 9 dB.}
10) _{Measured at the given Stressed Receiver Eye Closure Penalty and DCD component given in Fibre Channel}
PI Standard (2.03/2.18 dB & 40/80 ps).
