Transceiver Timing Characteristics
Parameter
LOS Assert Time
LOS Deassert Time
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.
