Notes:
1.Module circuit ground is isolated from module chassis ground
within the module.
2.should be pulled up with 4.7k – 10k ohms on host board to a
voltage between 3.15Vand 3.6V.
3.Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ pullup to
VccT inside the module.
4.Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host
may pull this contact up to Vcc_Host with a resistor in the range
4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+ module is
physically absent from a host slot.
5. RS0 and RS1 are module inputs and are pulled low to VeeT with
> 30 kΩ resistors in the module.
Digital Diagnostic Specifications
The transceivers can be used in host systems that require either
internally or externally calibrated digital diagnostics.

Notes:
1.When Operating temp.=0~70 ºC,the range will be min=-5,Max=+75
2. Internally measured
3. The accuracy of the Tx bias current is 10% of the actual current
from the laser driver to the laser
Typical Interface Circuit
Recommended power supply filter
Note:
Inductors with DC resistance of less than 1Ω should be used in
order to maintain the required voltage at the SFP input pin with
3.3V supply voltage. When the recommended supply filtering network
is used, hot plugging of the SFP transceiver module will result in
an inrush current of no more than 30 mA greater than the steady
state value
