Description
Digital state of SFF TX_ DISABLE Input Pin (1 = TX_DISABLE asserted)
Read/write bit for changing digital state of SFF TX_DISABLE function¹
Digital state of the laser fault function (1 = Laser Fault Detected)
Digital state of the SFF Sig_Det Output Pin (1 = Signal Detect DeAsserted)
Indicates transceiver is powered and real time sense data is ready. (0 = Ready)

Notes:
1. The response time for soft commands of the AFBR-59R5LZ is 100msec as specified by the MSA SFF-8472
2. Bit 6 is logic OR’d with the SFF TX_DISABLE input pin 8 either asserted will disable the SFF transmitter.
3. AFBR-59R5LZ meets the MSA SFF-8472 data ready timing of 1000 msec.
4. The logic level of the register “Signal Detect State” is inverse to the “Signal Detect” HW pin.
