QSFP28 EVB Active Module Performance Evaluation Test Board QSFP+
QSFP28 EVB Active Module Performance Evaluation Test Board QSFP+
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.
