Cisco SFP-50G-CU2.5M 25/50GBASE-CU SFP56 Cable 2.5 m | DAC, LSZH — SFP-50G-CU2.5M

Maintain low-latency connectivity between adjacent devices with Cisco’s 25/50GBASE-CU SFP56 cable in a 2.5 meter length. This direct attach copper assembly is designed for short-reach links where optical transceivers are unnecessary, helping reduce cost, power draw, and cable management complexity in high-density environments. The LSZH jacket adds a practical advantage for installations where reduced smoke and halogen content matter, such as data center pathways, enclosed racks, and regulated facilities. At 2.5 meters, the cable gives teams enough reach for clean routing between top-of-rack switches, servers, and aggregation points without excess slack. For infrastructure teams standardizing on Cisco optics and interconnects, this cable fits the role of a simple, dependable link component: no extra configuration, no transceiver pairing, and no unnecessary overhead. It is a straightforward choice when the requirement is to preserve port speed and keep the physical layer disciplined. Ideal For Connect top-of-rack switches to adjacent servers in a dense rack Link neighboring switches in a leaf-spine or aggregation layer Replace short optical runs where DAC is sufficient Standardize short-reach cabling in data center rows Why This Product 1 Shorter 2.5 meter reach for cleaner rack routing 2 LSZH jacket for enclosed-space cabling requirements 3 Direct attach copper instead of optical transceivers 4 Cisco-matched interconnect for SFP56 environments
