A brief video produced by Communications Supply Corporation (CSC) explains the "triple whammy" that has caused a spike in the price of cables - including and particularly copper-based twisted-pair cables.
In the past CSC has issued documents, or briefs, keeping its customers up to date on the pricing of such items as copper, polyvinyl chloride (PVC) and fluorinated ethylene propylene (FEP). The recently produced video does that as well, further explaining that all these materials have gone up in price and cable manufacturers have been unable to absorb their increased costs.
