We have some QM9700 NDR switches connected with original IB cables, if we use them together with your cables will there be any incompatibility problems?

NADDOD IB cables meet international standards, with good interoperability and compatibility, and are able to be paired together with the original cables.

Can the branch end of the O4O112-800G-DACH cable be downspeeded to NDR200?

Yes, it can be downspeeded to NDR200 for use with ConnectX-7 NDR200 OSFP port NICs.

Can the O4O112-800G-DACH cable be used with 400G IB NICs with QSFP112 ports?

No, QSFP112 and OSFP are two different package types with different form factors and cannot be used together.

Can NDR200 be used interconnected with HDR 200G?

No. The NDR200 is a 2-channel 112G PAM4 and the HDR 200G is a 4-channel 56G PAM4.

Description

NVIDIA/Mellanox MCP7Y50-N002 Compatible 2m (7ft) Twin-port 2x400G OSFP Finned Top to 4x200Gb/s OSFP Flat Top IB NDR Passive Copper Splitter Cable

NADDOD O4O112-800G-CU2H is an 800Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 4x200Gb/s OSFP Flat Top passive Direct Attach Copper (DAC) dual breakout (aka splitter) cable for 400Gb/s End-to-End Infiniband solutions. 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 an 800Gb/s Quantum-2 switch switch to OSFP-based 200Gb/s ConnectX-7 PCIe network adapter cards and BlueField-3 DPUs. NADDOD’s cable solutions provide power-efficient connectivity enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.

Product Highlights

Finned Top and Flat Top Unlock Optimal Application Scenarios

800G Breakout DAC integrates different heat sink designs of the two-end transceivers, unleashing powerful performance.

The 800G OSFP end transceiver adopts a finned top to provide the necessary thermal management when handling massive data, which is applied for Quantum-2 InfiniBand switches and Spectrum-4 Ethernet switches.

Each module on the two or four 400G OSFP breakout side has a flat-top design used in CX7 NICs and relies on heatsinks on the NIC ports to assist the module in cooling.

Questions & Answers

Ask a Question

I only use the No. 1 splitter IB cable and the rest of the branches are not installed on the card, which will affect the use of the No. 1 splitter cable.

No effect, after the port is configured with a split port, it is recognized as four logical ports inside the device, and each branch corresponds to a logical port, which does not affect each other.

Why are there no NDR AOCs?

OSFPs are very large and heavy and the fiber breaks easily. A two-splitter cable will have three large transceiver ends. A four-splitter cable will have five transceivers. That would almost certainly make it easy to break the fiber during installation - especially for a 30 meter AOC.

What is the maximum transmission distance of the O4O112-800G-DACH cable?

The passive DAC can provide up to 3M.
