Lenovo ThinkSystem 3M Passive DAC SFP Cable

Usage Area

The Lenovo ThinkSystem TCH 3M Passive DAC SFP cable is deployed in enterprise data center racks to establish direct 10GbE links between Lenovo ThinkSystem servers and compatible switches. It is used for short-range, high-throughput interconnects within a single rack or adjacent racks, supporting server-to-switch and switch-to-switch topologies. The cable is suitable for environments requiring low-latency, high-reliability connections without active electronics. Typical applications include storage networking, virtualization clusters, and high-performance computing fabric links.
