455604 is a high-performance power and data bus cable, also known as a shielded twisted-pair cable. It is composed of two individually shielded twisted pairs of copper wires, with each pair having a distinct different insulation sleeve for data and power. The shielding reduces any external electromagnetic interference, or EMI, to keep the signal pure and free of interference. This cable is commonly used to connect computers, peripherals, and other equipment to a central power source, allowing all of the signals to travel together along a single cable. It is also used to connect various pieces of equipment, as well as allowing digital video signals to be sent over the same cable as analog audio signals.
