Unanswered Question
Nov 13th, 2008

Dear all,

is there any way to intyerconnect a Cisco 6509 (which only takes XENPACK interfaces to my knowledge) with a NEXUS 7000 which only takes SFP+ interfaces with 10GB speed? What could I do here to be future proof?


I have this problem too.

A main feature of Cisco 10GBASE SFP+ modules includes Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link.

Connectors: Dual LC/PC connector (-SR and -LR), You can use OFC cable for connecting the 6509 to NEXUS 7000

So there is basically a cable that looks like SFP (SFP+) on one end and like GBIC (XENPAK) on the other?

Is this Twinax cable?

You need an LC to SC patch cord. The LC site connects to SFP optic and the SC site connects to Xenpak optic
