The Extreme Networks 25G Passive DAC SFP28 1m is a premier networking solution designed to elevate data transfer capabilities in data centers and high-performance network environments. This copper direct-attach cable spans 1 meter (3.28 ft), engineered for high-speed performance and reliable, low-latency connectivity between 25G-ready devices. Ideal for short-reach interconnects between servers, top-of-rack switches, and storage appliances, this passive DAC offers a cost-effective, plug-and-play alternative to optical fiber while maintaining robust signal integrity. The 1-meter length keeps cabling neat, promotes streamlined airflow, and simplifies cable management in dense rack layouts. As part of the Extreme Networks ecosystem, this SFP28 DAC cable delivers smooth interoperability with Extreme switches and a wide range of third-party 25G-capable ports, making it a versatile choice for leaf-spine fabrics, rack-to-rack links, and other high-bandwidth deployments. Whether upgrading a data-center fabric, supporting latency-sensitive workloads, or accelerating scalable storage networks, this DAC delivers consistent performance, easy deployment, and a favorable total cost of ownership.

• High-speed 25G performance with low latency - Capable of delivering 25 Gbps data rates with deterministic copper signaling to support time-sensitive applications, this passive DAC minimizes jitter and backpressure while maintaining tight latency budgets. It enables rapid data transfers between servers, ToR switches, and storage systems, enhancing virtualization, real-time analytics, and high-speed backups. Built for dense data-center fabrics, the 25G link benefits from precise terminations, reliable copper conductors, and stable signal integrity across short reaches.
• SFP28 form factor, passive copper DAC - The SFP28 duplex interface on both ends makes this a straightforward direct-attach copper solution for 25G interconnects. Being passive, it requires no external power or active electronics, reducing cabling complexity and energy consumption while offering a compact, field-ready option for rack installations. The SFP28 standard is widely supported across 25G-enabled devices, ensuring broad compatibility in mixed-vendor environments where fast, predictable interconnects are essential.
• 1 meter length optimizes data-center cabling - A precisely measured 1-meter (3.28 ft) reach suits many top-of-rack and server-to-switch scenarios, allowing tidy cable runs, minimal slack, and improved airflow. This length helps reduce bend radius stresses and simplifies cable management in dense racks, helping to keep pathways clear for cooling and maintenance while delivering consistent electrical characteristics for stable 25G signaling.
• Plug-and-play deployment with plug-and-play convenience - Designed for immediate use in compatible ports, this DAC requires no drivers or configuration. Simply insert into SFP28 ports on both devices, verify link status, and begin transferring data at 25G speeds. This ease of deployment accelerates time-to-value for new rack deployments, data-center refreshes, and temporary lab setups, while minimizing operational overhead and risk of misconfiguration.
• Broad compatibility and reliability for data-center fabrics - Engineered for robust interoperability with Extreme Networks devices and many third-party 25G-capable switches and NICs, this DAC cable is built to endure continuous operation in demanding data-center environments. High-quality copper, careful shielding, and precise manufacturing deliver dependable performance across varying temperatures and workloads, with durability that supports hot-swapping during maintenance windows in many environments.
