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.
