Cisco CVR-QSFP to Sfp10g QSFP-SFP Adapter Module

The Cisco CVR-QSFP-SFP10G (part number 74-9474-02) is a QSFP+ to SFP+ adapter (also known as a QSA - QSFP+ to SFP+ Adapter) that converts a 40 Gigabit Ethernet QSFP+ port on a Cisco switch into a 10 Gigabit Ethernet SFP+ port, allowing you to use standard 10G SFP+ transceivers or cables for lower-speed connections, crucial for flexible upgrades and port reuse in data centers.
