The Cisco QSFP to SFP or SFP+ Adapter (QSA) Module offers 10 Gigabit Ethernet and 1 Gigabit Ethernet connectivity for Quad Small Form-Factor Pluggable (QSFP)-only platforms. It allows smooth and cost-effective migration to 40 Gigabit Ethernet by providing an option to use lower-speed Small Form-Factor Pluggable (SFP) or Enhanced Small Form-Factor Pluggable (SFP+) modules in empty QSFP ports or when the other end of the network is running at lower speeds.
The Cisco CVR-QSFP-SFP10G network media converter is ideal for users requiring high-speed, 40-gigabit-per-second, single-mode QSFP+ to SFP form factor conversion for long-distance, high-capacity, low-delay optical network applications.
