U9601A 10G SFP+Test board

one, SFP+Test board type and communication interface type:

1、 SFP+Single-channel test board adopts parallel port andUSBTwo communication interfaces.

2、 Parallel andUSBTwo communication interfaces realize simulationI²C, The rate control is 100Kbps, Easy to be compatible with high and low speeds I²Cmoldpiece.

two, SFP+Test board functions:

1、 SFP+The functions implemented by the single-channel test board are: compatible11.7Gmodules at all speeds below;

2、 Parallel andUSBTwo communication interfaces are implementedI²CCommunication;Hardware control moduleTxDisableand hardware monitoringLOS，TxFaultstate;

3、 Real-time temperature monitoring,Real-time transmission and reception current measurement monitoring and overcurrent protection;Pull bias voltage output control, output voltage range from2.9~3.8VContinuously adjustable output between the two, suitable for the pull-bias voltage test of the module, the output voltage is high and the error is smaller than that of the5mV, Not affected by the total current of the external module;

4、 Hardware and software implementation modulesTxDisableandPower OnOFF（ Switching power), hardware and software are controlled independently.

5、 USBThe interface can support separate power supply (the current of the optical module is less than100mAin case).

three,  Notes:

1， Notice PCBAThere are also devices behind the bottom of the board. Conductive objects cannot be placed on the test to prevent short circuit from burning the board.

2, Adjust the input voltage to 5V, Do not turn the voltage up or reverse it to avoid burning the board.

3, test 10GWhen the module is used, it supports high-speed signals.TX，RXElectric signal wires need support18GFrequency signal cable.

Four,  SFP+The actual figure of the test board is described as follows:
