Cisco SFP-50G-CU1M= 25/50GBASE-CU SFP56 Cable 1 m LSZH | DAC, 50G — SFP-50G-CU1M=

Keep high-speed links tight, simple, and cost-controlled with Cisco’s 1 meter 25/50GBASE-CU SFP56 cable. Designed for short-reach interconnects, it supports 25G and 50G direct attach deployments where latency, power draw, and rack density matter more than optical reach. This cable is a practical fit for top-of-rack and adjacent equipment connections in modern data centers. The LSZH jacket helps reduce smoke and halogen exposure in enclosed spaces, making it a better choice for facilities with stricter safety requirements. At 1 meter, it is sized for clean rack-to-rack or within-rack runs that avoid excess slack and preserve airflow. For teams standardizing on Cisco switching and high-speed server connectivity, this cable offers a straightforward way to maintain consistent short-distance performance. It is especially useful where SFP56-capable ports are being used to connect high-throughput devices without introducing the added expense of transceivers and fiber. In dense infrastructure, that simplicity translates into faster deployment, fewer parts to manage, and a cleaner physical layer. Ideal For Connect adjacent Cisco switches in a top-of-rack deployment Link servers to nearby switching ports in a dense rack Replace optical modules on short intra-rack runs Standardize short-reach 25G or 50G cabling in data center rows Why This Product 1 Shorter and simpler than optical transceiver plus fiber pairs 2 LSZH jacket better suited to enclosed rack environments 3 1 meter length helps reduce slack in dense cabinets 4 Direct attach copper lowers parts count for adjacent links
