PARAMETER
Dice are tested at T
Tested at R
Voltage on BIAS pin is (V
Both the bias and modulation currents will be switched off if any of the current set pins are grounded.
Accuracy refers to part-to-part variation.
Assuming that the laser to monitor-diode transfer function does not change with temperature. Guaranteed by design and
characterization.
AC characteristics are guaranteed by design and characterization.
Measured with 622Mbps 0-1 pattern, LATCH = high.
PWD = (wider pulse - narrower pulse) / 2.
