SFP-50G-CU2.5M Cisco 25/50GbE SFP56 2.5m Direct Attach Copper Cable

This Cisco SFP-50G-CU2.5M is a direct attach copper (DAC) cable designed for high-speed data connections over short distances. It is commonly used to link network devices such as switches, servers, or storage systems within racks or across adjacent racks, where low latency and reliable throughput are critical.

Built for data centers and enterprise networks, this cable supports both 25G and 50G Ethernet speeds, making it suitable for environments requiring scalable and efficient connectivity. Network engineers and IT professionals often rely on these cables for cost-effective, straightforward connections without needing additional optical transceivers.

Key Features

• Delivers robust 25/50G speeds using SFP56 form factor
• 2.5 meter length ideal for rack-to-rack or in-rack setups
• Energy-efficient passive copper design
• Compatible with a range of Cisco switches and devices
• Low latency connection for performance-critical applications

This cable is typically deployed in data centers where short-range, high-bandwidth connections are frequent. It helps reduce equipment complexity by eliminating the need for separate transceivers and fiber cabling while maintaining signal integrity. In practice, it supports fast data transfer in environments like server farms, storage networks, and high-performance computing clusters.
