Notes:

1. Differential impedance is measured between D

2. These are unfiltered 20% - 80% values measured with a 550 MBd 101010 pattern.

3. Inter-channel Skew is defined for the condition of equal amplitude, zero ps skew input signals.

4. Deterministic Jitter (DJ) is defined as the combination of Duty Cycle Distortion (Pulse-Width Distortion) and Data Dependent Jitter. Deterministic

pattern with zero skew between the differential data input signals.

as for DJ and is measured with all channels operating.

6. The specified optical output power, measured at the output of a 2meter test cable, will be compliant with IEC 60825-1 Amendment 2, Class 1M

Accessible Emission Limits, AEL Regulatory Compliance section.
