NVIDIA AOC splitter, IB twin port HDR, 200Gb/s to 2x100Gb/s, OSFP to 2xQSFP56, 15m

The NVIDIA AOC Splitter is a high-performance active optical cable solution purpose-built for InfiniBand HDR networks. Designed to maximize port density and streamline data-center interconnects, this intelligent splitter takes a single 200 Gb/s HDR InfiniBand link from an OSFP host and fans it out into two independent 100 Gb/s QSFP56 channels. With a reachable length of 15 meters (49.21 feet), it blends long-reach flexibility with compact cabling, making it ideal for server racks, compute clusters, HPC environments, and AI-accelerated workloads where latency and bandwidth matter most. This twin-port HDR splitter combines robust signal integrity with a plug-and-play design, enabling administrators to simplify topology while preserving the performance of their InfiniBand fabric.

• Ultra-fast bandwidth split: Transforms a single 200 Gb/s InfiniBand HDR link into two discrete 100 Gb/s streams, enabling parallel data paths and improved network utilization without the need for extra host ports. This helps you scale out high-demand applications, accelerate data transfers, and optimize fabric efficiency across racks and clusters.
• Twin-port HDR capability: Maintains HDR InfiniBand characteristics across both outputs, delivering low latency, high reliability, and predictable performance for time-sensitive workloads such as HPC simulations, deep learning model training, and data-intensive analytics. The splitter preserves the quality of the original link while enabling dual-channel operation.
• OSFP input to QSFP56 outputs: Specifically engineered for OSFP host ports on the input side and dual QSFP56 endpoints on the outputs. This configuration supports modern, high-density data-center architectures and simplifies integration with a range of network devices and switches that support QSFP56 copper or optical interfaces.
• Extended reach with a compact form factor: The 15-meter (49.21-foot) length offers flexible deployment options within racks and cabinets, reducing the need for excessive patch cabling and enabling cleaner, more maintainable topologies. The AOC design minimizes electromagnetic interference and supports clean, organized data-center layouts.
• Durable, plug-and-play AOC design: As an Active Optical Cable splitter, it ships with integrated optics and electronics designed for reliable operation in data-center environments. Its rugged build, straightforward connection procedure, and low power consumption help administrators deploy high-speed links quickly while maintaining system uptime.

How to install NVIDIA AOC Splitter

Installing the NVIDIA AOC Splitter is a straightforward process designed to minimize disruption to your existing InfiniBand infrastructure. Follow these steps to ensure a proper setup and optimal performance:

• Step 1: Power down the host and ensure the system is safe for installation. Identify the OSFP host port that will feed the AOC splitter input and verify compatibility with HDR InfiniBand networks.
• Step 2: Connect the OSFP input end of the splitter to the designated host port using a compatible OSFP cable. Verify that the connector is fully seated and aligned to avoid insertion damage.
• Step 3: Connect the two QSFP56 outputs to their respective QSFP56 endpoints or adapters in your network devices. Use high-quality QSFP56 cables or optical links that match your deployment requirements and bandwidth goals.
• Step 4: Route the 15-meter AOC cable through the rack in a manner that minimizes bending and ensures a clean path with good airflow. Avoid sharp bends, kinks, and pressure points that could affect optical performance.
• Step 5: Power on the devices and verify link status. Use your fabric management tools to confirm that the single 200 Gb/s input is recognized and that the two 100 Gb/s outputs are independently negotiated. Run basic connectivity and throughput tests to confirm dual-path operation.
