To obtain full performance from a Cisco Nexus 3232C cluster-interconnect switch, the appropriate hot-swappable transceiver is the QSFP28. The Cisco Nexus 3232C switch supports 100 Gigabit Ethernet connectivity, and QSFP28 transceivers are designed to support this high-speed networking. QSFP+ and SFP+/SFP transceivers support lower bandwidths (40 Gbps and 10 Gbps respectively) and would not enable the full 100 Gbps performance that the switch is capable of delivering.
