The HP 850397-001 is a 3-meter, high-performance 100GB QSFP to 4x25GB SFP28 Direct Attach Cable (DAC), engineered to facilitate flexible and efficient connectivity between high-speed networking equipment. This innovative cable is designed to split a single 100GbE QSFP28 port into four independent 25 Gigabit Ethernet SFP28 ports. This functionality allows for versatile network configurations, such as connecting a high-capacity switch with QSFP28 ports to multiple servers or switches with 25GbE SFP28 interfaces, maximizing the utilization of available hardware and bandwidth. The cable provides a direct, low-latency, and cost-effective solution for short-distance links within data centers and between racks, ideal for deploying high-density networking environments that demand high throughput and low power consumption. The passive DAC technology ensures compatibility and optimal performance without the need for external power sources, making it a straightforward, plug-and-play option for upgrading existing infrastructure. Constructed with the highest quality materials, the HP 850397-001 cable is designed to withstand the rigors of a modern data center, offering reliability and durability for mission-critical applications. This product is a valuable tool for network administrators aiming to efficiently scale their network bandwidth and accommodate the growing demand for data processing and storage capacity.
