Cable manufacturers?


How many cable companies actually manufacture their own cable? 

Perhaps Mogami, Belden, Canare and a few others. I am willing to bet most cable companies do not manufacture their own cable, but simply buy cable, throw on some techflex or other custom jacketing, and do nice terminations. 

Anyone have any any actual Information?

For USA long-term thinking is a year or two out, for Chinese its 2-3 centuries . 
Chinese debt = zero, US debt three times what it could pay in 80 years .
Duh , . In 10 years yuan will be de-facto reserve currency .
 In 100 years there might be no USA at all let alone it's currency.
