network
The PLC-2/4 Cable network is a type of communications cable with shielding and twisted pair elements used in high speed data transfer. The cable consists of two to four insulated copper conductors, surrounded by an outer dielectric sheath. The conductors are twisted together to reduce interference from outside sources such as other cables. To further reduce interference, the PLC-2/4 cable is shielded with a metallic Mylar foil and four to seven braided aluminum shield wires that are also tinned-copper-clad steel (TCCS). The outer jacket is made of polyvinyl chloride (PVC) and is designed to protect the twisted pairs and the shielding from external mechanical hazards. The shielding is designed to prevent leakage of signals, while the twisted pair element of the cable reduces interference. PLC-2/4 cables are most commonly used in cable modems, digital broadband networks, and digital video systems.
