5. +3.3V Volt Electrical Power Interface
The SFP-10GE-T has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage is not allowed for
continuous operation.
Caution: Power consumption and surge current are higher than the specified values in the SFP MSA
6. Low-Speed Signals
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals (see section
VII, "Serial Communication Protocol"). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to
host_Vcc
