Description
Digital state of SFP Tx Disable Input Pin (1 = Tx_ Disable asserted)
Read/write bit for changing digital state of SFP Tx_Disable function Note 1)
Digital state of SFP Rate Select Input Pin (1 = full bandwidth of 2.488 Gbit) (Note 2)
Digital state of The SFP Tx Fault Output Pin (1 = Tx Fault asserted)
Digital state of The SFP LOS Output Pin (1 = LOS asserted)
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-5745Z does not respond to state changes on Rate Select Input Pin. It is internally hardwired to full bandwidth.
