Conditions
Time from rising edge of
TX_DISABLE to when the optical
output falls below 10% of nominal
Time from falling edge of
TX_DISABLE to when the modulated
optical output rises above 90% of
nominal
Time from power on or negation of
TX_FAULT using TX_DISABLE
Time from fault to TX_FAULT ON
Time TX Disable must be held high to
reset TX_FAULT
Time from LOS state to RX_LOS
assert
Time from non-LOS state to RX_LOS
de-assert
Time from rising or falling edge of
Rate Select input until receiver
bandwidth is in conformance with
