Notes:
1) Rising edge of TX_Disable to fall of output signal below 10% of nominal.
2) Falling edge of TX_Disable to rise of output signal above 90% of nominal. This only applies in normal operation,
not during start up or fault recovery.
3) From power on or negation of TX_Disable.
4) From power on or TX_Disable negated during power up, or TX_Fault recovery, until non-cooled power level 1
part (or non-cooled power level 2 part already enabled at power level 2 for TX_Fault recovery) is fully operational.
5) From falling edge of stop bit enabling power level 2 until non-cooled module is fully operational.
6) From falling edge of stop bit disabling power level 2 until module is within power level 1 requirements.
7) From Occurrence of fault to assertion of TX_Fault.
8) Time TX_Disable must be held High to reset TX_Fault.
9) From assertion till stable output.
10) From Occurrence of loss of signal to assertion of LOS.
11) From Occurrence of presence of signal to negation of RX_LOS.
