requirements for the system.
Determining Transceiver 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
the Hardware Compatibility
CAUTION: 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
Tool.
