Description
The Cisco CVR-4SFP10G-QSFP Reverse Adapter is designed to enable seamless connectivity between 10 Gigabit Ethernet SFP+ platforms and 40 Gigabit Ethernet QSFP+ links. This reverse adapter converts four SFP+ ports into a single QSFP+ interface, allowing organizations to leverage QSFP+ optics while preserving existing 10G infrastructure.
Ideal for data center and enterprise network environments, the CVR-4SFP10G-QSFP supports a cost-effective migration path to higher-bandwidth architectures without requiring immediate switch upgrades. Its compact, cable-based design provides installation flexibility while maintaining reliable signal integrity across supported QSFP+ modules.
This spare unit is well suited for network expansions, replacements, or staged upgrades where performance, compatibility, and scalability are critical.
