GIGALIGHT’s 800G QSFP-DD+OSFP/OSFP-RHS optical transceiver checker can be used to test QSFP/QSFP-DD/OSFP/OSFP-RHS module.The checker can read the internal memory EEPROM of the modules and display details of the EEPROM (such as the Part Number,Vendor Name,description and range.),monitor all DDM information.You can change the EEPROM if you know the module password. There are two types of ports1xQSFP/QSFP-DD + 1xOSFP/OSFP-RHS,GUI can be used optionally(not supported for simultaneous use).It combines the Serial Pattern Generator,Bit Error Rate Analyzer,estimate the FEC margin size.It provides common transmission rate for 8×53.125GBd PAM4 and 8×26.5625GBd PAM4.The friendly graphic user interface (GUI) provides clear monitoring for bit error rate, bit error counter,time,FEC margin size, status,selection of data rate and PRBS pattern.
