Direct Attach Copper CablesNVIDIA Mellanox Direct Attach Copper Cables are the lowest cost way to create 100G links. DACs are widely used to link servers to memory and storage subsystems because they are passive, consume zero power and have the lowest latency. Mellanox offers a wide range of products for 0.5m to 7m reaches, in SFP and QSFP form factors and data rates of QDR(40G), FDR10(40G), FDR(56G), EDR(100G) and HDR (200G).
In addition to meeting IBTA standards, LinkX certified cables are 100% tested in actual Mellanox systems to ensure optimal signal integrity and the best end-to-end performance. Mellanox DAC cables are designed for use in super computers that have the most stringent requirements. All Mellanox cables are tested to BER 1E-15 which is 1000x few errors than most others. Mellanox passive copper cables offer trouble free installation, long-term reliable operation and they work with 3rd-party switches and adapters.
