We have some QM9700 NDR switches connected with original InfiniBand cables. Will there be compatibility issues if we use them with your cables?

NADDOD InfiniBand cables comply with international standards, featuring excellent interoperability and compatibility. They work seamlessly with original cables.

What are the application scenarios of the O4Q56-400G-DACH cable?

It is mainly used to connect Quantum-2 NDR InfiniBand switches to HDR100 switches, ConnectX-6/7 QSFP56/QSFP112 network cards, and BlueField-2/3 DPUs.

Description

NVIDIA/Mellanox Compatible DAC 3m (10ft) 400Gb/s OSFP to 4x100Gb/s QSFP56 InfiniBand HDR Passive Copper Splitter Cable

NADDOD O4Q56-400G-CU3H is a passive Direct Attach Copper (DAC) cable with an OSFP-based twin-port 2x 200Gb/s connector to four QSFP56. DAC cables are the lowest-cost, lowest-latency, near zero power consuming, high-speed links available due to their simplicity of design and minimal components. Main use is linking Quantum-2 NDR InfiniBand switches to HDR100 switches, ConnectX-6/7 adapters, and/or BlueField-2/3 DPUs.

Questions & Answers

Ask a Question

If I only use one splitter of the 1-to-4 InfiniBand cable and leave the other splitters unconnected to the network card, will it affect the performance of the used splitter?

No, it won't. Once the port is configured for splitting, the device internally recognizes four logical sub-ports. Each splitter corresponds to a separate logical sub-port, so they operate independently without interfering with one another.

Why are there no NDR AOCs?

OSFP transceivers are big and heavy, which makes the fibers inside the AOC easy to break. A 2-splitter cable has 3 large transceiver ends, while a 4-splitter one has 5. This almost certainly increases the risk of fiber breakage during installation—especially for 30-meter AOCs.

What is the maximum transmission distance of the O4Q56-400G-DACH cable?

The passive DAC can provide a maximum transmission distance of 3 meters.
