QSFP28 EVB SFP Evaluation Board PAM4 Baud 25GBoud To 28GBoud

U9604 QSFP28 EVB

   This product is dedicated to the performance evaluation of active modules packaged with QSFP+ and QSFP28. The transmitting and receiving terminals have four inputs and outputs. The single-terminal NRZ rate ranges from 10G to 32Gbps and PAM4 baud rate ranges from 25GBoud to 28GBoud. And PAM4 50G, 100G, 200G products, using error code device, attenuator, oscilloscope and other equipment, to evaluate the active module of transmitting performance indicators (such as eye map related indicators), receiving performance indicators (such as sensitivity indicators), read and write module EEPROM information.
