Immersion-Cooled AOC Cable 100G QSFP28 SR4 Active Optical Cable Om3 Multimode

JTOPTICS® Immersion-Cooled 100G QSFP28 SR4 Active Optical Cable (AOC) is purpose-built for high-performance, high-density optical interconnect systems within immersion-cooled data centers, enterprise computing networks, and AI/HPC clusters. Designed specifically to operate reliably in dielectric liquid immersion cooling environments, this AOC module delivers 100Gbps aggregate bandwidth using 4×25Gbps parallel lanes over multimode fiber.

This advanced AOC employs a liquid-cooling-optimized structural design, including immersion-grade sealing, pressure resistance, and material compatibility enhancements to prevent liquid ingress, ensuring long-term mechanical stability and optical performance. The integrated MPO-12 fiber interface and compact cable structure support low-latency, high-density rack interconnect applications with flexible installation in submerged environments.

Supporting transmission distances of up to 70 meters over OM3 and 100 meters over OM4, the cable is ideal for short-reach, high-speed connections between switches, servers, and accelerators within immersion-cooling systems. Engineered for superior thermal handling and minimal electromagnetic interference, it maintains stable performance and energy efficiency under high-compute workloads.
