The SFP+ Passive Direct Attach Copper (DAC) Cable is a high-performance, cost-effective solution for short-reach 10Gb Ethernet and 10G Fibre Channel connections. Designed for maximum port density and low power consumption, this passive twinax cable enables hardware manufacturers and data-center operators to achieve efficient, flexible, and scalable network architectures.
With excellent signal integrity and zero active components, SFP+ DAC cables deliver ultra-low latency and reliable 10G performance—ideal for server-to-switch links, storage networks, and high-density rack environments. Each assembly meets or exceeds the electrical and mechanical requirements defined by Gigabit Ethernet and Fibre Channel industry standards.
