Notes:
1. Time from two-wire interface assertion of TX_DISABLE (A2h, byte 110, bit 6) to when the optical output falls below 10% of nominal. Measured
2. Time from two-wire interface de-assertion of TX_DISABLE (A2h, byte 110, bit 6) to when the modulated optical output rises above 90% of
3. Time from fault to two-wire interface TX_FAULT (A2h, byte 110, bit 2) asserted.
4. Time for two-wire interface assertion of Rx_LOS (A2h, byte 110, bit 1) from loss of optical signal.
5. Time for two-wire interface de-assertion of Rx_LOS (A2h, byte 110, bit 1) from presence of valid optical signal.
6. From power on to data ready bit asserted (A2h, byte 110, bit 0). Data ready indicates analog monitoring circuitry is functional.
7. Time from power on until module is ready for data transmission over the two-wire interface (reads or writes over A0h and A2h).
8. Time from stop bit to completion of a 1-8 byte write command. Measured from the stop bit, for a one t om four byte write the maximum cycle
9. Between STOP and START. See SFF 8431 Section 4.3

from falling clock edge after stop bit of write transaction.
nominal.
time is 40ms and for a five to eight byte write the maximum cycle time is 80ms.
