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
