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) _{For GbE applications only.}
4) _{Jitter (pk-pk) is measured using a 2}7_{–1 NRZ PRBS and a Digital Communications Analyzer.}
5) _{Measured at nominal data rate. These are unfiltered 20% - 80% values.}
6) _{Receiver characteristics are measured with a worst case reference laser.}
7) _{Fibre Channel PI Standard.}
8) _{Average optical power at which the BER is 1x10}–12_{. Measured with a 2}7_{–1 NRZ PRBS and ER = 9 dB.}
9) _{Measured at the given Stressed Receiver Eye Closure Penalty and DCD component given in Fibre Channel}
