Hi,

thanks for your answer, but those are the part numbers for the X2 transceivers... and i am wondering which SPF+s are supported when using the OneX X2-to-SFP+ converter...

Michael.

I'm sorry, misunderstood your question

included below is the table, SFP+ Modules, this is probably the documentation you found.

LR is goin to be supported, internal talks give 04/2011 as an estimate

let me know if this answers your questions.

Hey Michael,

There is a OneX transceiver that is compatible on the 4900M with IOS 12.2.50SG.  It basically plugs into a X2 port and concerts it to a SFP+ port.

You can use the SFP+ cables that have the optics built on the ends of the cable (the cost of the cable is cheap.)

These are copper based, like the TwinAX CX4 cables.

The cables come in 1, 3 and 5 meters.

SFP-H10GB-CU1M=     >>>Cisco 10GBASE-CU SFP+ cable, 1 meter (Version -02)

SFP-H10GB-CU3M=     >>>Cisco 10GBASE-CU SFP+ cable, 3 meter (Version -02)

SFP-H10GB-CU5M=     >>>Cisco 10GBASE-CU SFP+ cable, 5 meter (Version -02)

All this sounds great and that is why we went that way for a customer BUT there are compatibility issue with the cables right now.

I'm working through this.

So as an alternative we might use the SFP+ optic and fiber cable instead.

SFP-10G-SR=     >>>Cisco 10GBASE-SR SFP+ Module for MMF

Hope this helps.

ping me as needed.

Hi Ajay,

I need to deliver a solution to a customer with 4900M and Nexus 5000 but the Onex code in the Dynamic Configuration of 4900M isn't showed. I found the code CVR-X2-SFP10G of the Onex only in the http://www.cisco.com/en/US/prod/collateral/modules/ps5455/data_sheet_c78-547521.html.

I also saw this post with this consideration of the twinax cables. This issue about the twinax cables are now resolved or it's better deliver SFP+ optic with fibre cable  yet?

Thanks!

Heine.
