The Gigalight 40G QSFP+ & 100G QSFP28 optics checker is designed to be used to test the QSFP+/QSFP28 optics (optical transceivers, active optical cables, and direct attach cooper cables). It can read the internal memory EEPROM of the optics and display the details (Part Number, Vendor Name, etc.) and monitor the DDM information. It can also change the EEPROM (the Write protect password is required) like the cloud programmer do. In addition, it can measure the power of the module. The QSFP checker combines the Serial Pattern Generator and Bit Error Rate Analyzer. The friendly Graphic User Interface (GUI) provides clear monitoring for bit error rate, bit error counter, time, status, power of the QSFP optics, selection of data rate and PRBS pattern.
