What is the difference between O2Q112-800G-ACC and O2Q112-800G-DAC?

O2Q112-800G-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. O2Q112-800G-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 of O2Q112-800G-DAC cable?

It is mainly used for switches with OSFP ports. And the branch end connected to a 400G QSFP112 port of either ConnextX-7 network card or BlueFIeld-3 DPU.

Can the O2Q112-800G-ACC cable be used for 400G network cards with OSFP ports?

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

Description

NVIDIA/Mellanox Compatible 0.5m (1.6ft) Twin-port 2x400Gb/s OSFP Finned Top to 2x400Gb/s QSFP112 Flat Top Passive Copper Splitter Cable

NADDOD O2Q112-800G-CUA is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 2x400Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Flat Top passive Direct Attach Copper (DAC) dual breakout (aka splitter) cable for 400Gb/s End-to-End Ethernet solutions. The 8-channel Twin port OSFP end uses a finned top form-factor for use in OSFP switch cages. The two 400G ends support 4-channels of 100G-PAM4 (400G) 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.

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

I only use branch 1 for a two-part cable. Branch 2 is not installed to the bandwidth. Will it affect the use of branch 1 cable?

No, it won't affect.. After the port is configured with a split port, it is recognized as two logical split ports inside the device. Each branch line corresponds to a logical split port and doesn’t 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.

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.
