Description
The HPE Aruba Networking 400G QSFP-DD to 4x QSFP56 100G 7m Active Optical Cable (R9B48A) delivers ultra-high-speed connectivity with superior reliability. Designed for modern data center and high-performance computing environments, this AOC splits one 400G QSFP-DD port into four individual 100G QSFP56 connections, offering streamlined deployment for large-scale networking fabrics.
This active optical cable enables fast and flexible 400G connectivity over a 7-meter optical link while reducing cable bulk and weight compared to traditional copper. Ideal for short-reach, high-density interconnects between switches and network devices.
