Immersion-Cooled 800G QSFP-DD SR8 Active Optical Cable Om3 Multimode

JTOPTICS® Immersion-Cooled 800G QSFP-DD SR8 Active Optical Cable (AOC) is an advanced high-bandwidth optical interconnect solution engineered specifically for immersion liquid-cooled AI data centers, hyperscale cloud platforms, and HPC supercomputing environments. Designed to withstand full liquid immersion in dielectric cooling fluids, the cable features a sealed optical engine structure, corrosion-resistant components, and optimized heat dissipation for long-term reliability and thermal stability.

The module utilizes 8 parallel lanes of 100G PAM4 signaling, delivering an aggregate 800Gbps transmission capability and enabling ultra-high-speed, low-latency interconnects for GPU clusters, switch fabrics, and computing accelerators. It supports up to 100 meters transmission over OM4 multimode fiber, making it ideal for short-range server-to-switch and switch-to-switch connectivity inside immersion tanks.

Equipped with a MPO-16 APC male optical connector, the AOC ensures extreme signal integrity, low optical loss, and minimized reflection, meeting demanding requirements of high-performance, high-density networking architecture.
