Passive Direct Attach Copper Cable

        X-Krama's high-speed Direct Attach Cable (DAC)  uses silver-plated conductors and foamed insulated core wires as materials, and adopts wire-pair shielding and overall shielding to form a high-speed cable. High-speed cables have excellent attenuation performance, low delay and anti-interference, and can realize high-frequency broadband transmission. There are 30~24AWG specifications and various structures such as 2P, 4P or 8P.

        The advantages of DAC cables have become the preferred solution for users in short-distance application scenarios, and are widely used in data center interconnection scenarios such as SATA storage devices, RADI system scenarios, core routers, and 10G or 40G Ethernet.
