HPE 845416-B21 Direct Attach Coppe100GB QSFP28 to 4X25GB SFP28 3M DAC

Detailed Specifications

This high-speed, passive copper breakout cable is engineered for reliable short-reach connectivity in modern data centers and high-performance computing clusters. It provides a cost-effective solution for connecting a single 100GbE QSFP28 switch port to four separate 25GbE SFP28 ports on servers, storage arrays, or other network appliances. The HPE 845416-B21 directly addresses the need for high-density port aggregation, enabling a streamlined and efficient top-of-rack network architecture. The core of this product's value lies in its passive Direct Attach Copper (DAC) design. This technology offers significantly lower latency and power consumption compared to active optical cables or transceivers, making it an ideal choice for in-rack communication where performance is critical. By splitting a 100Gbps uplink into four 25Gbps downlinks, it maximizes switch port utilization and reduces the total number of cables and transceivers required, simplifying infrastructure while lowering capital and operational expenses. Designed for seamless deployment, this 3-meter cable is perfectly suited for top-of-rack (ToR) or middle-of-row (MoR) configurations, connecting servers and storage directly to the aggregation switch within the same or adjacent racks. Its factory-terminated QSFP28 and SFP28 connectors ensure plug-and-play installation with compatible HPE networking equipment. The robust, pre-assembled design eliminates the complexities of fiber optic termination and provides a dependable, low-maintenance link for mission-critical traffic.
