Lenovo ThinkSystem 3m Passive DAC SFP+ Cable

Equipment Overview

The Lenovo ThinkSystem TCH 3M Passive DAC SFP+ is a 3-meter passive copper cable designed for direct-attach connectivity between servers and switches within the Lenovo ThinkSystem family. Its primary purpose is to establish a high-speed 10GbE link with minimal latency, making it suitable for data center and enterprise rack deployments. The cable integrates SFP+ connectors on both ends, providing a reliable, cost-effective alternative to optical transceivers for short-range interconnects. This model is intended for use in environments where consistent, low-power 10 Gbps throughput is required between adjacent equipment.
