Notes:
6. Differential impedance is measured between D
7. The specified optical output power, measured at the output of a 2 meter test cable, will be compliant with IEC 60825-1 Amendment 2,
8. Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the low (“0”) state
9. These are unfiltered 20% - 80% values measured with a 550 MBd 101010 pattern.
10. Inter-channel Skew is defined for the condition of equal amplitude, zero ps skew input signals.
11. Deterministic Jitter (DJ) is defined as the combination of Duty Cycle Distortion (Pulse-Width Distortion) and Data Dependent Jitter.
12. Total Jitter (TJ) includes Deterministic Jitter and Random Jitter (RJ). Total Jitter is specified at a BER of 10
