Hi Mike,

Belden list a number of STP cables related to categories in their
master catalogue (the one I've got is copyright 1993):
"DataTwist" (tm) Four:
Third party verified to Category 4
2 pair   4 pair
1597A    1456A - 24 Gage solid
1599A    1458A - 24 Gage solid, plenum rated
         1560A - 22 Gage solid
         1562A - 22 Gage solid, plenum rated
"DataTwist" (tm) Five:
Third party verified to Category 5
2 pair   4 pair
1589A    1584A - 24 Gage solid, RJ-45 Compatible
         1633A - 24 Gage solid
1591A    1586A - 24 Gage solid, plenum rated
Other than the data in the catalogue, that's all I know.
Both Farnell and RS (the two major broad line Electronic distributors in
the UK) list screened Category 5 cable from other vendors.
