SFP timing parameters for SFP management

Parameter	Symbol	Min.	Max.	Unit	Unit Conditions
TX_DISABLE Assert	t_off		10		Time from rising edge of TX_DISABLE to
				μsec	when the optical output falls below 10% of
time
					nominal
TX_DISABLE	t_on		1	msec	Time from falling edge of TX_DISABLE to
					when the modulated optical output rises
Negate time
					above 90% of nominal
Time to initialize,					From power on or negation of TX_Fault using
including reset of	t_init		300	msec
TX_FAULT					TX Disable.
TX Fault Assert	t_fault		100	μsec	Time from fault to TX fault on.
Time
TX_DISABLE to	t_rest	10		μsec	Time TX Disable must be held high to reset
reset					TX_Fault
