The Cisco OneX Converter Module (model CVR-X2-SFP10G), also known as a converter module, is a hot-swappable input/output (I/O) device that slides into a 10-Gigabit Ethernet X2 slot on a switch. It converts the 10-Gigabit X2 interface into a single 10-Gigabit SFP+ interface. It is supported on many platforms using X2 interfaces. Which platforms are they? In fact, many people are confused about the CVR-X2-SFP10G compatibility. In this blog, I will give some knowledge about the compatibility for Cisco OneX CVR-X2-SFP10G Converter Module.
CVR-X2-SFP10G Supported SFP+ Modules and Patch Cords
Not all SFP+ modules can be used for Cisco CVR-X2-SFP10G OneX converter module. Table below lists the SFP+ modules and twinax cables that available.
| SFP+ Module Number | Description |
| SFP-10G-SR | Cisco 10GBASE-SR SFP-Plus transceiver module for MMF, 850nm wavelength |
| SFP-10G-LR | Cisco 10GBASE-LR SFP-Plus transceiver module for SMF, 1310nm wavelength |
| SFP-H10GB-CU1M | Twinax cable assembly, 1m, 30 AWG |
| SFP-H10GB-CU3M | Twinax cable assembly, 3m, 30 AWG |
| SFP-H10GB-CU5M | Twinax cable assembly, 5m, 24 AWG |
Table below lists the fiber-optic cabling specifications for the SFP+ modules that you install in the converter module. Each port must match the wavelength specifications on the other end of the cable, and the cable must not exceed the stipulated cable length. The SFP modules using fiber-optic connections need fiber-optic cables with LC/PC or LC/UPC connectors.
| SFP Module | Wavelength | Fiber Type | Core Size (micron) | Modal Bandwidth (MHz/km) | Cable Distance |
| 10GBASE-SR | 850 | MMF | 62.5
62.5 50 50 50 |
