    Interface Support for the QFX10002

    The QFX10002 has quad small form-factor pluggable plus (QSFP+) ports for use as uplinks, downlinks, or as access ports. These 40-Gigabit Ethernet ports support QSFP+ transceivers, QSFP28 transceivers, QSFP+ direct-attach copper (DAC) cables, and DAC breakout cables (DACBO). Each QSFP+ port on either a QFX10002-72Q or a QFX10002-36Q can be configured to operate as a 10-Gigabit Ethernet interface by using a breakout cable or as a single 40-Gigabit Ethernet interface.

    The QFX10002 also supports using small form-factor pluggable (SFP) and small form-factor pluggable plus (QSFP+) transceivers to connect the management ports. These transceivers are not supported for use in the uplinks, downlinks, or access ports.

    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 QFX10002 is located at

    Caution: If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.
