The Cisco CVR-QSFP-SFP10G (also known as the QSFP to SFP+ adapter or QSA module) enables data centers and enterprise networks to maximize investment protection and simplify upgrades. It allows network operators to insert a 10G SFP+ optical or copper transceiver into a 40G QSFP+ slot, delivering full interoperability and reducing the need for dedicated 10G ports.
