Cisco CVR Port Converters and Adapters - Refurbished, Used, New

Best Selling

Cisco CVR port converters and adapters let one pluggable port type accept a different module, so an existing switch or router port can run the optic or cable a link needs. This collection carries new, refurbished and used Cisco CVR adapters. Refurbished and used units are tested before they ship.

Which Cisco CVR adapter do I need?

Start with the port on your switch or router, then the module you want to run in it.

QSFP port, 10G or 1G link: CVR-QSFP-SFP10G. Cisco states that it converts a QSFP port into an SFP or SFP+ port and supports all SFP+ optics and cable reaches plus several 1 Gigabit Ethernet SFP modules.
X2 slot, Gigabit links: CVR-X2-SFP. Cisco lists the Catalyst 3750-E and 3560-E Series, the Catalyst 4500 E-Series Supervisor 6-E and the Catalyst 4500 E-Series 6-port 10 Gigabit Ethernet line card among its platforms.
40G CFP port, four 10G links: CVR-CFP-4SFP10G. Each converted port takes a Cisco 10GBASE SFP+ module.
100G CFP2 port, CPAK optic: CVR-CFP2-CPAK10. Cisco supports it with CPAK modules that use a 10x10G electrical interface, such as the SR10 and 10x10G LR types, at the 100GBASE Ethernet rate only, not OTN rates.
SFP+-only switch, 40G at the far end: CVR-4SFP10G-QSFP. It takes four SFP+ ports and presents one QSFP+ port, so a 10G platform can link to a 40 Gigabit Ethernet port using a QSFP+ optic, active optical cable or active copper cable.

Are optics included with these adapters?

Cisco states that SFP+ modules for the CVR-CFP-4SFP10G are ordered separately, and that the CVR-CFP2-CPAK10 has no optics of its own, so reach and connector type come from the CPAK module you install. For anything else included, check the listing.

Does the CVR-4SFP10G-QSFP plug straight into the switch like a transceiver?

No. Cisco describes it as a housing with an attached cable, 1.75 m in total length, that mounts on a separate bracket or a 2RU tray holding up to eight adapters. Check the listing for whether mounting hardware is included.

How do I confirm my platform supports a CVR adapter?

Cisco's data sheets for these adapters refer to Cisco's transceiver compatibility matrices for the supported switch and router models. Check your exact chassis or line card there before ordering.
