Siemon 4x25Gb/s DAC, QSFP28 High Speed Interconnect, Breakout Passive Direct Attach Copper Cable

The Siemon 4x25Gb/s DAC QSFP28 High Speed Interconnect Breakout Passive Direct Attach Copper Cable provides reliable, low-latency connectivity for modern data centre and enterprise environments. It is compatible with QSFP28 and SFP28 networking equipment and offers a cost-effective OEM alternative while delivering exceptional performance, compatibility, and long-term reliability across multi-vendor network infrastructures.
It supports a 100Gb/s QSFP28 connection that breaks out into four independent 25Gb/s SFP28 channels, making it ideal for connecting high-density switches to multiple servers, storage systems, or network devices. It is suitable for cloud computing platforms, enterprise networks, hyperscale data centres, AI workloads, and high-performance computing environments where efficient port utilisation and high-bandwidth connectivity are essential.
It has industry-standard QSFP28 to 4x SFP28 interfaces and features a hot-pluggable form factor for quick, tool-free installation and replacement without disrupting active network operations. Its 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.
