Connecting 2.5G to 10Gig Xenpak Module interface

Unanswered Question
Jul 2nd, 2008

Hi All,

We are exploring a possibility to connect a 2.5G output from a DWDM node to 7600 router having a 10Gig xenpak module. Is this possible ?

Any help is really appreciated

A 2.5G interface cannot be connected directly to a 10G interface.

What are you trying to accomplish?

We are trying to use the esiting 10Gig port as temporary solution to connect a 2.5g or even 1 Gig output from the DWDM.

Any help would be really appreciated

This would be no differet than plugging a 100Base-FX port into a 1GigE port. It just can't be done without some type of mediation device (switch, router, other?).

It is not clear what your network looks like so it is challenging to propose solutions.
