Juniper QFX-SFP-1GE-LX SFP (mini-GBIC) Module

The optical transceivers installed in QFX Series devices support digital optical monitoring (DOM) and digital diagnostic monitoring (DDM). DDM not only performs optical monitoring but also electrical monitoring, such as power supply voltage. You can view the diagnostic details for these transceivers from the CLI by issuing the operational mode CLI command show interfaces diagnostics optics. The command does not give any output for copper transceivers or transceivers not purchased from Juniper Networks.
