Cisco SFP-50G-CU3M 3 m 25/50GBASE-CU SFP56 Cable | DAC, Enterprise — SFP-50G-CU3M

Keep short-reach 25/50 GbE connections direct and predictable with the Cisco SFP-50G-CU3M copper cable. At 3 meters, it is suited to rack-level and adjacent-rack interconnects where optical transceivers are unnecessary and a passive copper path is the right fit. This cable is designed for environments that want to preserve port density, reduce component count, and simplify physical connectivity between compatible SFP56 interfaces. The LSZH jacket is a practical choice for enclosed equipment rooms and other installations where reduced smoke and halogen content are preferred. For network teams building out leaf-spine fabrics, top-of-rack aggregation, or short server-to-switch runs, a direct attach copper cable can be a cost-efficient way to maintain high throughput without adding the complexity of separate optics and fiber patching. It is a straightforward fit for infrastructure teams that value clean rack design and consistent link behavior. Ideal For Connecting adjacent switches in a rack or across neighboring racks Linking servers to top-of-rack switches over short distances Building short-reach 25/50 GbE interconnects without optics Deploying in equipment rooms where LSZH cable is preferred Why This Product 1 3 meter reach for rack-level connections 2 Direct attach copper instead of optics 3 LSZH jacket for cleaner installations 4 Built for 25/50GBASE-CU environments
