Conditions/Comments
Time for the rising edge of ALS (Tx_DISABLE) to when
the bias current falls below 10% of nominal
Time for the falling edge of ALS to when the modulation
current rises above 90% of nominal
From power-on or negation of FAIL using ALS
Time to fault to FAIL on
Time Tx_DISABLE must be held high to reset Tx_FAULT.
