Use Case
C8220 is the pick when a server needs dual-rail 200G East-West for scaled-out inference rather than a single 800G uplink: two QSFP112 ports give independent paths to two leaf switches, and the SyncE/PPS timing chain makes it suitable for disaggregated AI clusters where precise time distribution matters.
