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
