From detection of loss of signal
to assertion of RX_LOS
From detection of presence of
signal to negation of RX_LOS
fall of output signal below 10%
of nominal
to rise of output signal above
90% of nominal. Time
indicated is under steady-state
temperature conditions.
TX_DISABLE HIGH before
TX_DISABLE set LOW
TX_Fault will assert before the
device is outside of specified
wavelength range
