Table 13. EEPROM Serial ID Memory Contents - Address A2h, Byte 110 (AFCT-5705Z family only)
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 function
1
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. AFCT-5705Z does not respond to state changes on Rate Select Input Pin. It is internally hardwired to full bandwidth.
