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
