From detection of loss of signal to assertion of RX_LOS.
From detection of presence of signal to negation of RX_LOS.
Rising edge of TX_DISABLE to fall of output signal below 10% of nominal.
Falling edge of TX_DISABLE 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 specifi ed wavelength range.
