Bit #
Status/Control Name Description
7
Tx Disable State
Digital state of SFP Tx Disable Input Pin (1 = Tx_ Disable asserted)
6
Soft Tx Disable
Read/write bit for changing digital state of SFP Tx_Disable function¹
5
Reserved
4
Rx Rate Select State
Digital state of SFP Rate Select Input Pin (1 = full bandwidth of 155 Mbit)²
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. AFBR-5705Z does not respond to state changes on Rate Select Input Pin. It is internally hardwired to full bandwidth.
