QSFP28 EVB SFP Evaluation Board With Four Inputs And Outputs 10G to 32Gbps

This product is designed to evaluate the performance of QSFP+ and QSFP28 packaged active modules with four input/output channels in each transmitting and receiving terminal. Single-terminal NRZ rates range from 10G~32Gbps and PAM4 baud rates range from 25GBoud~28GBoud. Supported modules include NRZ 40G and 100G products. And PAM4 50G, 100G, 200G products, using error meter equipment, attenuator and oscilloscope equipment, to evaluate the active module's transmission performance indicators (such as eye image related indicators), reception performance indicators (such as sensitivity indicators), read and write module EEPROM information, etc.

The real object is shown in the picture below:

Product:

1.QSFP+QSFP28 package interface, suitable for QSFP+, QSFP28, PAM4 50G100G200G optical module.

2.Support NRZ rate range: 10.3125G~32Gbps.

3.PAM4 baud rate ranges from 25GBd to 28GBd

4.Four-way TX, four-way RX electrical interface type: 40GHz 2.92mm female, CML level input/output;

5, support current real-time monitoring and overcurrent protection.

6, Support the power supply voltage deviation test, the voltage range is 2.8~4.V adjustable, meet the module deviation of the minimum 3.0V and maximum 3.6V voltage test, as well as real-time voltage monitoring, the default 3.3V output, according to the current module real-time adjustment of the output voltage, to ensure that the power supply voltage under different loads is stable within the range of 10mV.

7, support industrial temperature environment application.

8. The MCU I2C rate is about 100KHz, and data is transferred to I2C through MCU to read and write EEPROM information of module.

9, communication mode: USBHID, no driver, directly read and write I2C data to module and MCU through DLL API.
