TX_ DISABLE State

Digital state of SFP TX_ DISABLE Input (1 = TX_DISABLE asserted)

Note 1

6

Soft TX_ DISABLE

Read/write bit for changing digital state of TX_DISABLE function

Note 1, 2

2

TX_FAULT State

Digital state of the SFP TX_FAULT Output (1 = TX_FAULT asserted)

Note 1

1

RX_LOS State

Digital state of the SFP RX_LOS Output (1 = RX_LOS asserted)

Note 1

0

Data Ready (Bar)

Indicates transceiver is powered and real time sense data is ready. (0 = Ready)

Notes:

1. The response time for soft commands of the AFCT-701ASDZ is 100 msec as specified by SFF-8472.

2. Bit 6 is logic OR’d with the SFP TX_DISABLE input on contact 3; either asserted will disable the SFP+ transmitter.
