NVIDIA 980-9I118-00H030 | 400G to 2x200G InfiniBand HDR AOC Splitter, 30m

Q: What is the primary use case for this AOC splitter cable?
A: This cable is designed to connect a single 400Gb/s OSFP port on an NDR InfiniBand switch to two legacy 200Gb/s QSFP56 ports on HDR switches, network adapters, or DPUs. It enables efficient migration and integration between different generations of InfiniBand infrastructure in high-performance computing and AI data centers.

Q: Can I use only one of the two QSFP56 connectors?
A: Yes, after configuring the port for split mode, the OSFP port is recognized as two logical ports internally. Each QSFP56 connector corresponds to one logical port, so they operate independently without affecting each other.

Q: What is the difference between flat-top and finned-top OSFP connectors?
A: The 980-9I118-00H030 features a flat-top OSFP connector design, which has a lower profile compared to finned-top variants. Both provide the same electrical performance, but the flat-top design may offer different thermal and physical characteristics depending on the switch port requirements.

Q: Is this cable compatible with Ethernet applications?
A: While the cable uses similar 400Gb/s to 2x200Gb/s PAM4 signaling that supports both InfiniBand and Ethernet protocols, it is specifically designed and optimized for InfiniBand HDR applications. Compatibility with Ethernet depends on the host system and firmware configuration.

Q: What fiber type is required for this AOC?
A: This is an active optical cable with integrated, pre-terminated connectors and embedded multimode fiber. No additional fiber infrastructure is required—the cable is a complete plug-and-play solution with all optical components built in.
