Teradyne GbX can handle the speed easily and you can get them in
small sections,perhaps augmenting your existing connector scheme?
The connectors with well controlled impedance tend to be large by
design, but it is possible to characterize and run smaller
connectors at the speeds you are looking at. Characterizing and
controlling isolation (xtalk) is as important as simple impedance
control. At 2.5Gbps you can also start benefiting from carefull
design of the launch into the connector you choose as this often
causes more signal degradation than the connector itself.
Enjoy...
