CAT6 Requires Shielded Connectors?

As I recently posted in the ethernet group, for the purpose of reducing alien crosstalk, according to IEEE studies, the shield (foil) does not need to be grounded. Not grounding it reduces the problems with ground loops and such.

But my question wasn't about how to ground shielding in the connector.... My question was such shielding required at all.

If I find CAT6 cables with shielding in the connector, how am I going to determine whether it is connected to ground anyway?

The suggestion of some is that foil shielded cable helps against alien crosstalk, which seems likely to be a problem at 10G if cables are packed into a cable tray or raceway. Another solution is to put thicker outer insulation on which keeps the pairs farther apart. For that purpose, the IEEE found and I agree, ungrounded foil shield works.

IEC 60603-7-4 is for the unshielded 250 MHz connector (aka Cat.6). IEC 60603-7-5 is for the shielded beast.
