What is the transmission distance of the O4Q112-800G-ACC cable?

Active DAC can provide 4M and 5M.

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 have good interoperability ,compatibility. It can be used with original cables.

What is the difference between O4Q112-800G-ACC and O4Q112-800G-DAC?

O4Q112-800G-DAC is a passive copper cable. The connector of the passive copper cable does not contain active components and can provide a direct electrical connection between the corresponding cable ends. The longest transmission distance is 3m. O4Q112-800G-ACC is a passive copper cable with integrated equalizer circuit. It can extend the length up to 4 meters and 5 meters while maintaining low latency and low power consumption of 1.5W and 0.6W respectively.

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

It is mainly used for switches with OSFP ports, with the branch end connected to a 200G QSFP112 port of either ConnextX-7 network card or BlueFIeld-3 DPU.

Can the O4Q112-800G-ACC cable be used for 200G network cards with OSFP ports?

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

Description

NVIDIA/Mellanox MCA7J75-N004 Compatible Active Copper Splitter Cable, Twin Port 800Gb/s to 4x200Gb/s, OSFP Finned Top to 4xOSFP Flat Top, 4 meters

NADDOD O4Q112-800G-AC4 is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 4x200Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Flat Top Active Copper Cable (ACC) quad breakout (aka splitter) cable for Ethernet networking. The switch end OSFP has a finned top for additional cooling and the QSFP112 adapter end is flat topped and uses riding heat sinks on the OSFP cage. The ACC contains eight high-speed electrical copper pairs, each operating at data rates of up to 100Gb/s using 100G-PAM4 modulation. The “active” term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters.

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 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

Can this cable be compatible with the NVIDIA Spectrum-4 switch?

It can meet compatibility requirements.

If I only use 3 out of 4 branches of the branch cable and leave one branch uninstalled on the network card, will it affect the usage of the three branches?

No, it won't affect. After port configuration and splitting, internally in the device, it is recognized as multiple logical ports. Each branch of the cable corresponds to a logical port, and they do not affect each other.

Why are there no 800G AOCs?

OSFP is very large and heavy, and the fiber can break easily. A two-branch cable will have 3 large transceiver ends, and a four-branch cable will have 5 transceivers. This will almost certainly easily lead to fiber breakage during installation - especially for a 30m long AOC.

This product solves our issue for longer distances where DAC cannot be used. It is evidently more cost-effective than modules.
