This 1m (3ft) 1.6T OSFP XDR InfiniBand passive high-speed cable is purpose-built to deliver ultra-low-latency, high-bandwidth connectivity for NVIDIA/Mellanox-based high-performance computing (HPC), AI, and data center fabrics. Designed as a cost-effective, plug-and-play solution, it supports line-rate 1.6Tbps (1600Gbps) throughput with OSFP XDR form-factor connectors, ensuring seamless integration with next-generation InfiniBand HDR/QDR systems and compatible network switches, hosts, and accelerators.

Built with premium-grade copper conductors and a robust shielded design, the cable minimizes signal interference and crosstalk, maintaining consistent signal integrity across critical 1.6Tbps workloads. Its passive construction eliminates the need for external power or active signal regeneration, simplifying deployment while reducing overall power consumption. The top-closed, durable housing provides excellent protection against dust and physical damage, making it suitable for both rack-scale and edge computing environments with strict reliability requirements.

Fully compliant with InfiniBand industry standards and backward-compatible with mainstream NVIDIA/Mellanox OSFP-based hardware, this cable supports low-latency, high-throughput fabric expansion for AI training clusters, scientific computing, and real-time data analytics. With a 1m (3ft) form factor optimized for short-rack and top-of-rack (ToR) connections, it delivers reliable performance with zero configuration, making it an ideal choice for rapid network deployment, system upgrades, and lab testing environments.
