Juniper QFX10002 Hardware Manual page 34

The default configuration is independent 40-Gigabit Ethernet for all 72 ports. For 100-Gbps or 10-Gbps
channelization operation, the ports operate within port groups. Every 3 ports compose a port group. See
Table 11 on page 25 and
Table 11: QFX10002-72Q Port Capacities
Per Port Group
1 x100 Gbps
3 x 40 Gbps
12 x 10 Gbps
The second and sixth port in each 6XQSFP+ socket can be configured to support:
• 100-Gigabit Ethernet using 28-Gbps QSFP28 optical transceivers and 100-Gbps active optical cables
(AOCs). When a QSFP28 transceiver is inserted into the ports marked with a fine black line
underneath the socket and the port is configured for 100-Gigabit Ethernet, the two adjacent ports
are disabled and the QSFP28 is enabled for 100-Gigabit Ethernet.
• 40-Gigabit Ethernet using QSFP+ optical transceivers or 40-Gbps direct attach copper (DAC) cables.
• 10-Gigabit Ethernet using DAC breakout cables (DACBO). When configured for channelization, a
breakout cable converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet
ports.The two adjacent QSFP+ ports in the port group are also configured for channelization at the
same time. You cannot configure a single port for channelization.
Switch Ports
Each of the 24 QSFP28 ports support:
• 100-Gigabit Ethernet QSFP28 transceivers
• 100-Gigabit Ethernet active optical cables (AOCs)
• 40-Gigabit Ethernet QSFP+ transceivers
• 40-Gigabit Ethernet QSFP+ DAC cables
• 40-Gigabit Ethernet QSFP+ to 10-Gigabit Ethernet SFP+ direct attach copper breakout (DACBO)
cables
The remaining ports support:
