Measured with a laser equivalent resistive load.
Burst Enable Delay is measured as the time between the instant when the BEN+ signal going from low to high reaches 50% of its amplitude and
the instant at which the modulation current or the bias current (whichever takes longer) reaches 90% of its final value.
the instant at which the modulation current or the bias current (whichever takes longer) goes below 10% of its final value.
