Juniper ACX7100-32C Hardware Manual page 20

• Thirty-two quad small form-factor pluggable (QSFP28) transceivers (ports 0 through 31) that operate
at 100-Gbps speed when you use QSFP28 transceivers or at 40-Gbps speed when you use QSFP+
transceivers.
NOTE: You can configure port 31 as a 1-Gigabit SFP grandmaster port by using a QSA
adapter to convert the QSFP28 port to a 1-Gigabit SFP port.
• Four double density quad small-form factor pluggable (QSFP56-DD) ports (ports 32 through 35) that
are configured as 400GbE ports by default.
The QSFP56-DD network ports support:
• QSFP56-DD transceivers
• QSFP28-DD transceivers
• QSFP28 transceivers
• QSFP+ transceivers
• Active optical cables (AOC)
• Direct attach copper (DAC) cables
