800G Active Optical Cables（AOC）
The 800G Active Optical Cable (AOC) series redefines data-center interconnect performance by combining the simplicity of a pluggable copper cable with the reach and signal integrity of embedded optics. Engineered in the compact QSFP112 form factor, each AOC delivers an aggregate 800 Gb/s bandwidth over four 200 Gb/s parallel lanes—ideal for next-generation spine-leaf fabrics, AI/ML clusters, and high-performance computing environments.
