SFP timing parameters for SFP management

Parameter				Symbol	Min.	Max.	Unit			Unit Conditions
TX_DISABLE Assert								Time	from	rising edge	of TX_DISABLE to
				t_off		10	μsec	when the optical output falls below 10% of
time
								nominal
TX_DISABLE								Time	from	falling edge	of TX_DISABLE to
				t_on		1	msec	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 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
