Network Ports

The QFX5220-32CD network ports (0 to 31) support:
400-Gbps QSFP-DD direct attach copper (DAC) cables
400 Gbps active optic cable (AOC) (starting in Junos OS Evolved Release 19.3R2)
100-Gbps QSFP28 transceivers
100 Gbps active optic break outcables (AOCBO) QSFP28 to four SFP25G interfaces
100-Gbps QSFP28 to 25-Gbps SFP28 direct attach copper break out (DACBO) cables (100 Gbps breaks
out to 4 independent 25-Gbps interfaces)
The 10-Gbps network ports 32 and 33 support small form-factor plus (SFP+) transceivers.

Setting Port Speed and Channelization

The default port speed for ports 0 through 31 is 400 Gbps. Only QSFP-DD optics inserted in these ports
will link without configuration. See
