T
Figure 1. Required Input Signal and Output Polarity
Note 1: Dice are tested and guaranteed at T
Note 2: Tested with R
Note 3: Both the bias and modulation currents will be disabled if any of the current set pins are shorted to ground.
Note 4: Guaranteed by design and characterization. This assumes that the laser to monitor diode transfer function does not change
Note 5: See the Typical Operating Characteristics for worst-case distributions.
Note 6: AC characteristics are guaranteed by design and characterization.
Note 7: Total I
Note 8: Input signal is a 622Mbps, 2
Note 9: Input signal is a 622Mbps, 11110000 pattern.
Note 10:PWD = (wider pulse – narrower pulse) / 2.
