Low speed electrical control pins and 2-wire interface
In addition to the 2-wire serial interface, the SFP+ module has the following low speed pins for control and
status:
‧ TX_Fault
‧ TX_Disable
‧ RS0/RS1
‧ MOD_ABS
‧ RX_LOS
1 TX_Fault
.TX_Fault is a module output pin that when High, indicates that the module transmitter has detected a fault
condition related to laser operation or safety.
The TX_Fault output pin is an open drain/collector and must be pulled p to the Host_Vcc with 4.7k-10k
ohms on the host board
2 TX_Disable
TX_Disable is a module input pin. When TX_Disable is asserted High or Left open, the SFP+ module
transmitter output must be turned off. The TX_DIS pin must be pulled up to VccT in the SFP+ module..
3 RS0/RS1
RS0 and RS1 are module input rate select pins and are pulled low to VeeT with a > 30kΩ resistor in the
module. RS0 is an input hardware pin which optionally selects the optical receive data path rate coverage
for an SFP+ module. RS1 is an input hardware pin which optionally selects the optical transmit path data
rate coverage for an SFP+ module.
4 MOD_ABS
Mod_ABS is pulled up to Host_Vcc with 4.7k-10k ohms on the host board and connected to VeeT or VeeR
in the SFP+ module. MOD_ABS is then asserted “High” when the SFP+ module is physically absent from
a host slot. In the SFP MSA (INF8074i) this pin had the same function but is called MOD_DEF0.
5 SCL/SDA
SCL is the 2-wire interface clock and SDA is the 2-wire interface data line. SCL and SDA are pulled up to
a voltage in the range of 3.14V to 3.46V on the host.
6 RX_LOS
RX_LOS when High indicated an optical signal level below that specified in the relevant standard. The
RX_LOS pin is an open drain/collector output and must be pulled up to host Vcc with a 4.7k-10k ohms on
the host board.
RX_LOS assert min and de-assert max are defined in the relevant standard. To avoid spurious transition
of RX_LOS a minimum hysteresis of 0.5 dB is recommended.
