Nickel-plated copper is often used in high-temperature applications and withstands up to 450°C. Nickel plating also offers corrosion and wear resistance If the cable is designed for. Ultra-High Temperature Wire & Cables, which operate at 450°C, provide remarkable thermal resistance, making them excellent for demanding industrial applications. Depending on the temperature range, manufacturers use polyolefin copolymer, fluoroethylene propylene, polytetrafluorethylene as well as silicone, which is also found in baking. At significantly higher temperatures, PVC cables can no longer keep up and cables with other sheath materials are required.

DAC is a passive cable composed of copper conductors that transmit high-speed electrical signals differentially between devices. While its connectors resemble optical modules in appearance, DAC is not a true optical module—it lacks internal laser components and performs no electro-optical or optical-electrical. DAC, short for Direct Attach Cable, is generally translated as Direct Attach Cable or Direct Attach Copper Cable. DACs are classified into active cables and passive cables.
