Lenovo 2M OSFP800 to 4x QSFP56 DAC, 800G | Direct Attach, Data Center

Built for short-reach 800G interconnects, Lenovo’s 2 m OSFP800 to 4 x QSFP56 DAC gives infrastructure teams a direct attach option for tightly packed racks and adjacent equipment. The cable is intended for environments where the shortest practical path is the right path: less slack, less congestion, and fewer cable-management compromises. The OSFP800 end connects to the host platform, while the four QSFP56 ends support breakout-style connectivity to compatible downstream devices. That makes it a strong fit for switch fan-out, aggregation, and high-density server connectivity in modern data center fabrics. Compared with optical assemblies, DAC can be a cost-effective choice for very short runs when the deployment stays within its reach envelope. At 2 m, this cable is aimed squarely at rack-scale interconnects where signal integrity, simplicity, and physical neatness are more valuable than extended distance. For teams building around 800G platforms, it helps keep the fabric compact and serviceable without adding unnecessary complexity.
