1) _{Into multimode fiber, 62.5 µm or 50 µm diameter.}
2) _{Deterministic Jitter is that jitter measured by a bathtub scan, using a 2}7_{–1 NRZ PRBS, and extrapolating to}
1 BER.
3) _{Total Jitter is that jitter measured by a bathtub scan, using a 2}7_{–1 NRZ PRBS, and extrapolating to 1x10}–12 _BER.
4) _{Jitter (pk-pk) is measured using a 2}23_{–1 NRZ PRBS and a Digital Communications Analyzer.}
5) _{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.
6) _{Receiver characteristics are measured with a worst case reference laser.}
7) _{Average optical power at which the BER is 1x10}–12_{. Measured with a 2}23_{–1 NRZ PRBS and ER = 9 dB.}
8) _{See Figure 3.}
