Transceiver Digital Diagnostic Monitor (Real Time Sense) Characteristics
(T
Notes:
1. Temperature was measured internal to the transceiver. Valid from = -10 °C to +85 °C.
2. Reference voltage is 3.3 V.
3. Valid from 0 to 50 mA, avg.
Transceiver Timing Characteristics
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. With RX input power less than -6dBm and greater than -21dBm.
