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.
