Can the NDR200 be interconnected with the HDR 200G?

No, the NDR200 is a dual-channel 112G PAM4, while the HDR 200G is a quad-channel 56G PAM4.

If I use only 3 of the 4 breakout branches and leave one branch unconnected, will the other three work properly?

No, it will not affect operation. After port configuration and breakout, the device recognizes the interface as multiple logical ports. Each branch corresponds to an independent logical port and does not affect the others.

We have some 800G OSFP port switches connected with original cables, will there be any incompatibility issues if we use them with your cables?

NADDOD cables comply with international standards and offer excellent interoperability and compatibility. They can be used together with original vendor cables without issue.

Can the branch end of the O4Q112-800G-CU1H cable be used for a 400G QSFP112 port network card?

In general, 400G QSFP112 network cards can support lower speeds such as 200G, so you can use this cable.

Description

NVIDIA/Mellanox MCP7Y40-N02A(980-9I75S-00N02A) Compatible DAC 2.5m (8.2ft) Twin-port 2x400Gb/s OSFP Finned Top to 4x200Gb/s QSFP112 Flat Top InfiniBand NDR Passive Copper Splitter Cable

NADDOD O4Q112-800G-CUCH is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) to 4x200Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) passive Direct Attach Copper (DAC) quad breakout (aka splitter) cable for 400Gb/s End-to-End Infiniband and Ethernet solutions. The 8-channel Twin port OSFP end uses a finned top form-factor for use in Quantum-2 and Spectrum-4 switch cages. The four 200G ends support 2-channels of 100G-PAM4 (200G) and use a flat top QSFP112 for use in ConnectX-7 adapters and BlueField-3 DPUs using riding heat sinks on the connector cage. 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.

Questions & Answers

Ask a Question

What are the main application scenarios for the O4Q112-800G-CU1H cable?

It is used with OSFP-port switches, breaking out to 200G QSFP112 ports on ConnectX-7 NICs or BlueField-3 DPUs.

What is the difference between O4Q112-800G-AC1H and O4Q112-800G-CU1H?

The O4Q112-800G-CU1H (DAC) is a passive copper cable without active components, providing the lowest cost, near-zero power consumption, and ultra-low latency for 800G to 4×200G InfiniBand and Ethernet interconnects within 3 meters. In contrast, the O4Q112-800G-AC1H (ACC) features an integrated equalizer circuit, extending the transmission distance up to 5 meters.

Can the O4Q112-800G-CU1H be used with 200G OSFP network cards?

No, it cannot be used. QSFP112 and OSFP are two different form factors with inconsistent sizes, and they cannot be used together.
