Axiom 845418-B21-AX 100GBASE-CR4 QSFP28 to 4 SFP28

Support high-density 100 GbE architectures with this Axiom 100GBASE-CR4 QSFP28 to 4 SFP28 passive DAC cable. The breakout format lets one QSFP28 port connect to four SFP28 endpoints, making it a strong fit for fan-out designs where port utilization and rack efficiency are priorities. By using passive direct attach copper, it avoids the added cost and power requirements of separate optical modules while keeping short-reach links straightforward to deploy. This cable is well suited to environments that need to distribute bandwidth across multiple 25 GbE connections from a single 100 GbE uplink. That makes it useful in leaf-spine fabrics, aggregation layers, and storage or compute clusters where predictable short-distance performance is more important than long-haul reach. The result is a cleaner cabling plan with fewer parts to source, install, and maintain. For teams standardizing on HPE-compatible infrastructure, Axiom provides a replacement path that aligns with enterprise procurement needs. When the goal is to maximize port density and keep short-run interconnects efficient, this passive DAC breakout cable delivers a focused, cost-conscious answer without adding complexity.
