Status/Control Name

Description

7

Tx Disable State

Digital state of SFP Tx Disable Input Pin (1 = Tx_ Disable asserted)

6

Soft Tx Disable

5

Reserved

4

Rx Rate Select State

3

Reserved

2

Tx Fault State

Digital state of the SFP Tx Fault Output Pin (1 = Tx Fault asserted)

1

Rx LOS State

Digital state of the SFP LOS Output Pin (1 = LOS asserted)

0

Data Ready (Bar)

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

Notes:

1. Bit 6 is logic OR’d with the SFP Tx_Disable input pin 3 ... either asserted will disable the SFP transmitter.

2. AFCT-5705Z does not respond to state changes on Rate Select Input Pin. It is internally hardwired to full bandwidth.
