The SFP+ 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.
Macroreer Offer 10GBASE Transceivers supported by optical interface over single-mode fiber-optic (SMF) and multimode fiber-optic (MMF) cables.
