Product Features
Technical Overview
This direct attach cable utilizes twinaxial copper construction to deliver 25 Gbit/s throughput over distances up to 3 meters. The SFP28 connectors on both ends are designed to interface seamlessly with SFP28 network ports, providing a direct electrical connection that eliminates the need for separate transceivers. The passive architecture means the cable operates without signal amplification, reducing complexity and potential points of failure in the link.
The cable supports 25GBase-CU standards, ensuring interoperability with compliant networking equipment. Its copper core facilitates high-speed data transmission with minimal latency, while the robust jacket material protects against physical wear and electromagnetic interference. This combination of specifications makes it suitable for high-performance computing, storage area networks, and data center interconnects.
