An Ethernet Crossover cable is used to connect two PCs directly together, without using a hub or switch in between. Each cable is made of 24AWG stranded pure copper conductor pairs with 50µm gold plated contacts (short body). Most budget cables skimp with only 10µm. Each cable features color matched, snagless, strain relief boots.Monoprice Cat6 cables are made of 100% pure bare copper wire, as opposed to copper clad aluminum (CCA) wire, and are therefore fully compliant with UL Code 444 and National Electrical Code TIA-568-C. 2 fire and safety standards, which require pure bare copper wire in Cat6 communications cables.
