CVR-QSFP-SFP10G Use Case
Enterprise Data Center Port Optimization
Leverage the CVR-QSFP-SFP10G QSFP to SFP10G adapter to convert underutilized 40GbE QSFP+ uplinks into 10GbE SFP+ ports. This enables rapid, non-disruptive 10GbE port expansion for servers and storage without forklift upgrades, delivering up to 30% CAPEX reduction, higher rack-density efficiency, and seamless integration with existing 10GbE infrastructure.
Multi-Vendor Network Integration in M&A
Deploy the CVR-QSFP-SFP10G adapter to bridge QSFP+ interfaces on one vendor’s core switches with SFP+ modules on another’s access switches during mergers or technology consolidations. This approach preserves legacy 10GbE assets, accelerates project timelines by up to 50%, minimizes interoperability issues, and maintains enterprise-grade performance and reliability.
Cost-Efficient Branch Office Connectivity
Use the CVR-QSFP-SFP10G QSFP to SFP10G adapter at remote or branch sites where only QSFP+ ports are available on compact routers. This simplifies inventory by eliminating the need for additional media converters, cuts OPEX through reduced spare-parts stocking, and guarantees robust 10GbE link performance for business-critical applications and disaster-recovery paths.

Which Cisco devices support the CVR-QSFP-SFP10G adapter?
The adapter is supported on Cisco Nexus 7000, Nexus 9000, Catalyst 6500/6800 series switches and UCS Fabric Interconnects with QSFP+ ports.
What data rates are supported by the CVR-QSFP-SFP10G adapter?
Each SFP+ port supports 10 Gbps, delivering up to 40 Gbps aggregate bandwidth from a single QSFP+ slot.
Is the CVR-QSFP-SFP10G adapter hot-swappable?
Yes. The adapter is fully hot-swappable, allowing installation or removal without powering down the switch or router.
Which SFP+ transceivers are compatible with this adapter?
It supports all MSA-compliant 10G SFP+ modules, including 10GBASE-SR, 10GBASE-LR, 10GBASE-ER and copper DAC SFP+ transceivers.
What cable types and distances can I achieve?
With the appropriate SFP+ module it supports multimode fiber up to 300 m (10GBASE-SR), single-mode fiber up to 10 km (10GBASE-LR) or copper DAC up to 10 m.
Does the adapter require any software configuration?
No special configuration is needed. Cisco IOS and NX-OS automatically recognize the adapter and connected SFP+ modules.
