QSFP+ Transceivers
Table 1-11 lists the supported QSFP+ transceivers and provides a brief description of each.
SFP+ Transceivers
The enhanced Small-Form-Factor Pluggable (SFP+) 10-Gigabit Ethernet transceiver is a bidirectional
device with a transmitter and receiver. It has a 20-pin connector on the electrical interface and duplex
LC connector on the optical interface. Currently, the Cisco Nexus 2000 Series FEX supports the
short-range SFP and long-range SFP transceiver. Table 1-12 describes the SFP+ transceivers used with
the Cisco Nexus 2248PQ FEX.
