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-DAC 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-DAC 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.

Can the branch end of the O4Q112-800G-DAC 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

Cisco Compatible Passive Copper Splitter Cable, Twin Port 800Gb/s to 4x200Gb/s, OSFP Finned Top to 4xQSFP112 Flat Top, 1m

NADDOD O4Q112-800G-CU1 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 passive Direct Attach Copper (DAC) quad breakout (aka splitter) cable for 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 four 200G ends support 2-channels of 100G-PAM4 (200G) and use a flat top QSFP112 connector cage adapters. 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

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.

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.
