Determining Transceiver Support for the QFX5110

The port panel of the QFX5110-48S supports 48 logical 10-Gigabit Ethernet ports. These data ports (0 through 47) support either 1-Gigabit small form-factor pluggable (SFP) or 10-Gigabit Ethernet Ethernet small form-factor pluggable plus (SFP+) transceivers. You can also use SFP+ DAC cables and 10-Gigabit active optical cables (AOC) in any access port.

The remaining 4 QSFP28 ports (48 through 51) support speeds of 40 Gbps or 100 Gbps. Each port can be configured as an independent 100-Gigabit Ethernet port or as an independent 40-Gigabit Ethernet port. These port are usually used as uplinks. In 40-Gigabit Ethernet mode, these ports can be channelized using QSP+ to SFP+ DAC breakout (DACBO) cables.

You can find information about the optical transceivers supported on your Juniper device by using the Hardware Compatibility Tool. In addition to transceiver and connection type, the optical and cable characteristics–where applicable–are documented for each transceiver. The Hardware Compatibility Tool enables you to search by product, displaying all the transceivers supported on that device, or category, by interface speed or type. The list of supported transceivers for the QFX5110 is located at


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.
