Notes:
1)
Time from rising edge of TX_DISABLE to when the optical output falls below 10% of nominal
2)
Time from falling edge of TX_DISABLE to when the modulated optical output rises above 90% of
nominal
3)
From power on or negation of TX_Fault using TX Disable
4)
Time from fault to TX fault on.
5)
Time TX Disable must be held high to reset TX_Fault
6) Time from LOS state to Rx LOS assert
7) Time from non-LOS state to Rx LOS deassert
