Immersion-Cooled AOC Cable 200G QSFP56 SR4 Om3 Multimode

JTOPTICS® Immersion-Cooled 200G QSFP56 SR4 Active Optical Cable (AOC) is engineered for high-density networking and high-performance computing environments that utilize liquid immersion cooling systems. Designed to deliver exceptional performance under submerged operating conditions, this AOC provides 200Gbps aggregate throughput, enabled by 4 parallel optical lanes operating at 50G PAM4 with reliable Forward Error Correction (FEC).

Optimized for immersion-cooling architectures using dielectric fluids, the AOC incorporates advanced liquid-sealed structural engineering, material compatibility enhancements, and pressure-resistant optical housing to ensure long-term operational integrity. It maintains high-speed data transmission with excellent signal integrity, thermal resilience, and minimal power consumption—making it ideal for large-scale clusters and next-generation AI infrastructures.

The integrated MPO-12 connector supports high-density optical interconnect deployment, allowing flexible rack-to-rack connectivity in submerged systems. Supporting distances up to 70 meters over OM3 and 100 meters over OM4 multimode fiber, this cable provides reliable, low-latency connectivity for modern liquid-cooled server and switch platforms.
