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