1m(3ft) Dell Compatible 400G OSFP Flat Top to 400G QSFP-DD Ethernet Active Optical Cable
The 400G QSFP-DD to OSFP-RHS active optical cable is a pluggable, parallel, fiber-optic QSFP-DD to OSFP-RHS AOC for Ethernet applications. It is designed for short-range multi-lane data communication and interconnect applicatijons. This active optical cable is compliant with IEEE 802.3bs-400GAUI-8, QSFP-DD MSA, and OSFP MSA.
Thin and lightweight AOC cables simplify cable management, enabling an efficient system airflow, which is critical in high-density racks. It is used extensively in cloud and supercomputers due to its low cost, high-value proposition, and increased reliability.
