Description

NVIDIA/Mellanox MCA7J65-N004 Compatible ACC 4m (13ft) Twin-port 2x400Gb/s OSFP Finned Top to 2x400Gb/s QSFP112 Flat Top Active Copper Splitter Cable

NADDOD O2Q112-800G-AC4H is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) to 2x400Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Active Direct Attach Copper (ACC) dual 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 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. The "active" term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters while maintaining very low-latency and very low-power.

Questions & Answers

Ask a Question
Q:
What is the difference between O2Q112-800G-AC1H and O2Q112-800G-CU1H?
A:
The O2Q112-800G-CU1H is a passive copper cable. It contains no active components in the connectors and provides a direct electrical connection between both ends, with a maximum transmission distance of up to 3 meters. The O2Q112-800G-AC1H is an active copper cable (ACC) with an integrated equalization circuit. This allows it to support longer reach — up to 4 or 5 meters — while maintaining low latency and low power consumption (approximately 0.6 W to 1.5 W, depending on cable length).
Q:
Can the O2Q112-800G-AC1H cable be used with 400G network cards that have OSFP ports?
A:
No. QSFP112 and OSFP are different form factors with different physical dimensions, so they are not compatible and cannot be used together.
Q:
If I only use one branch of a 1-to-2 cable and leave the other branch unconnected on the network card, will it affect the operation of the first branch?
A:
No, it will not affect the operation of the active branch. After port configuration and breakout, the device recognizes the interface as two independent logical ports. Each cable branch maps to its own logical port, and they operate independently.
