Few cable brands make their own product - Kimber, Transparent and Cardas do, but they are the exception. Most cable companies are a guy at his computer when he gets home from his day job who contracts out production to Belden, which would be U.S. made (some designs really are very advanced and there are but a small handful of manufacturers who have the requisite manufacturing expertise). Others have their designs made overseas, while some have it done in the U.S. and overseas.
