Cisco CVR-X2-SFP10G
X2 to SFP+ Adaptor module, Original Cisco
Product Highlights
Upgrading your 10 Gigabit Ethernet infrastructure shouldn't mean ripping out perfectly functional switches. The Cisco CVR-X2-SFP10G OneX Converter Module solves this exact problem by converting a 10 Gigabit Ethernet X2 port into a 10 Gigabit Ethernet SFP+ port — letting you adopt the smaller, more widely available SFP+ form factor without replacing your existing hardware.
This genuine Cisco adapter plugs directly into any supported X2 slot and accepts standard SFP+ transceiver modules, giving you the flexibility to use either X2 or SFP+ optics across your network. It's hot-swappable and plug-and-play, so there's no downtime and no configuration overhead during deployment.
The CVR-X2-SFP10G is ideal for organizations running Cisco Catalyst 3560-E, 3750-E, 4500, 4900, 6500 Series, or Nexus 7000 switches that want to standardize on SFP+ optics across campus, data center, or service provider environments. By enabling a gradual, node-by-node migration from X2 to SFP+, this converter module protects your existing investment while giving you a clear path to modern transceiver technology — all at a fraction of the cost of a full hardware refresh.
Features & Benefits
Seamless Form Factor Conversion
The CVR-X2-SFP10G converts a 10 Gigabit Ethernet X2 port into a 10 Gigabit Ethernet SFP+ port at full line rate. This allows you to use modern, cost-effective SFP+ transceivers in legacy X2 slots — eliminating the need to upgrade switches or line cards just to change optic form factors.
Hot-Swappable, Plug-and-Play Design
The module is fully hot-swappable and requires no software configuration. Simply insert the converter into an X2 slot and plug in your SFP+ transceiver — the port comes up automatically. This minimizes maintenance windows and simplifies deployment for network operations teams.
Investment Protection for Legacy Infrastructure
Rather than replacing entire switches or supervisor modules to gain SFP+ connectivity, the OneX Converter Module extends the useful life of your existing X2-equipped platforms. This translates directly into capital expenditure savings and a smoother, phased migration strategy.
Broad Cisco Platform Support
The CVR-X2-SFP10G is supported across a wide range of Cisco switching platforms including the Catalyst 3560-E, 3750-E, 4500, 4900, ME 4900, and 6500 Series, as well as the Nexus 7000 Series. This broad compatibility makes it a versatile tool for multi-platform environments.
Deployment Scenarios
Campus Network Migration
Organizations running Catalyst 3750-E or 3560-E switches with X2 uplink ports can use the CVR-X2-SFP10G to adopt SFP+ optics incrementally. This enables a phased migration to SFP+ without disrupting campus access or distribution layer connectivity.
Data Center Interconnect Standardization
Data centers with mixed X2 and SFP+ platforms can standardize on a single SFP+ transceiver inventory. The converter module eliminates the need to stock both X2 and SFP+ optics, reducing spare parts overhead and simplifying procurement.
Service Provider Edge Upgrades
Service providers running Catalyst 4500 or 6500 Series chassis at the network edge can leverage the CVR-X2-SFP10G to connect to newer SFP+-based equipment upstream without replacing edge switches that are still within their operational lifecycle.

Frequently Asked Questions
| Part Number | Product | Key Difference |
|---|---|---|
| CVR-X2-SFP10G= | Cisco OneX Converter Module (Spare) | Identical module sold as an individual spare — same functionality as CVR-X2-SFP10G but orderable separately outside a bundle. |
| CVR-QSFP-SFP10G | Cisco QSA Module (QSFP to SFP+) | Converts a QSFP+ port to SFP+/SFP rather than X2 to SFP+ — designed for newer 40G-capable platforms needing 10G/1G downlink flexibility. |
| CVR-X2-SFP | Cisco TwinGig Converter Module | Converts one X2 port into two 1G SFP ports instead of one 10G SFP+ port — suited for GbE downlinks rather than 10GbE migration. |
