Siemon 25Gb/s DAC, SFP28 High Speed Interconnect, Passive Direct Attach Copper Cable

The Siemon 25Gb/s DAC SFP28 High Speed Interconnect Passive Direct Attach Copper Cable delivers reliable, low-latency connectivity for modern data centre and enterprise environments. It is compatible with SFP28 networking equipment and provides a cost-effective OEM alternative while ensuring outstanding interoperability, performance, and long-term reliability across multi-vendor network infrastructures.
It supports data transfer rates of up to 25Gb/s, making it ideal for connecting switches, servers, storage systems, and network adapters in racks or between adjacent racks. It is suitable for enterprise networks, cloud computing platforms, virtualised infrastructures, and high-performance computing environments where high-bandwidth, short-range connectivity is essential for maintaining efficient network performance.
It has industry-standard SFP28 interfaces and features a hot-pluggable form factor for quick, tool-free installation and replacement without disrupting active network operations. The passive construction doesn’t need external power, which helps to reduce energy consumption while maintaining good signal integrity over short cable distances.
Each cable is tested for compatibility, durability, and reliability across supported platforms, while its advanced shielding minimises EMI to ensure data transmission is stable, secure, and consistent in demanding networking environments.
