IMOD is the total modulation current sink capability for a differential driver. IMOD = I
Refers to the voltage between the pin for which the compliance voltage is specified and VEE.
The pattern used is a repetitive sequence of eight 1s followed by eight 0s at 11.3 Gbps.
Measured using the high speed characterization circuit shown in Figure 3.
The pattern used is K28.5 (00111110101100000101) at a 11.3 Gbps rate.
Only includes current in the VCC pins.
Without laser diode loaded.
