Bare Copper Wire vs. CCA Wire

We use only pure bare copper on patch cables to guarantee our quality, we do not use any CCA or CCS or other materials.

What is CCA wire?
CCA is the abbreviation for “Copper clad aluminum＂wire.
Compare to pure copper wire, CCA wire is cheaper and in lower weight. However, the tensile strength of CCA wire is also lower than that of pure copper wire, and it is easier to be broken down. It may also cause transmission failure in construction.
Even it is claimed to have the same conductivity with “slightly” higher resistance, there will be data loss in the transmission. This will cause the transmission speed to slow down and it won’t able to meet the transmission speed requirements in the long run.

As more and more data is transmitted over the Internet cable and the application of PoE, these problems will eventually emerge. Long-term and reliable partnerships are not an easy job, we insist to pure copper wire only, with 100% component test. We provide reliable products to our partners and continue to deliver good quality products to our customers.
