2. Module identification

Connect JNP-QSFP-100G-CWDM module to JUNIPER QFX5200-32C switch, the module can be normally LINK, the port indicator light up; module information can be normally recognized by the switch, such as module type, model, serial number, rate, transmission distance, etc.; DOM data can be read, and DOM data are within the threshold range, no alarm phenomenon. The DOM data can be read, and the DOM data are all within the threshold range without alarms.
