We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.
The Juniper Networks Technical Assistance Center (JTAC) provides complete support for Juniper-supplied optical modules and cables. However, JTAC does not provide support for third-party optical modules and cables that are not qualified or supplied by Juniper Networks. If you face a problem running a Juniper device that uses third-party optical modules or cables, JTAC may help you diagnose host-related issues if the observed issue is not, in the opinion of JTAC, related to the use of the third-party optical modules or cables. Your JTAC engineer will likely request that you check the third-party optical module or cable and, if required, replace it with an equivalent Juniper-qualified component.
Use of third-party optical modules with high-power consumption (for example, coherent ZR or ZR+) can potentially cause thermal damage to or reduce the lifespan of the host equipment. Any damage to the host equipment due to the use of third-party optical modules or cables is the users’ responsibility. Juniper Networks will accept no liability for any damage caused due to such use.
The Gigabit Ethernet transceivers installed in EX4300 switches
support digital optical monitoring (DOM): You can view the diagnostic
details for these transceivers by issuing the operational mode CLI
command show interfaces diagnostics
optics.
The transceivers support DOM even if they are installed in ports configured as Virtual Chassis ports (VCPs).
