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.
Serial Interface for ID and Digital Diagnostic Monitor
The SFP+MX transceiver support the 2-wire serial communication protocol as defined in the SFP+ MSA. The standard SFP+ serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, This SFP+ transceivers provide an enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X(A0h), so the originally monitoring interface makes use of the 8 bit address(A2h), so the originally defined serial ID memory map remains unchanged. The structure of the memory map is shown in Table1.

Digital Diagnostic Specifications
The SFP+MX transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.
| Parameter | Symbol | Units | Min. | Max. | Accuracy | Note |
| Transceiver temperature | DTemp-E | ºC | -45 | +90 | ±5ºC | 1 |
| Transceiver supply voltage | DVoltage | V | 2.8 | 4.0 | ±3% | |
| Transmitter bias current | DBias | mA | 0 | 80 | ±10% | 2 |
| Transmitter output power | DTx-Power | dBm | -7 | +1 | ±2dB | |
| Receiver average input power | DRx-Power | dBm | -13 | 0 | ±2dB |
Notes:
1. Internally measured
2. 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
