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 > 30k

 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. RS1 is commonly connected to VeeT or VeeR in the legacy SFP 
modules. The host needs to ensure that it will not be damaged if this pin is connected to VeeT or VeeR in 
the 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
