What is the difference between OSFP-800G-ACCH and OSFP-800G-DACH?

OSFP-800G-DACH is a passive copper cable with a connector that does not contain active components, provides a direct electrical connection between the corresponding cable ends, and has a maximum transmission distance of 2m. An ACC is a passive DAC with a pre-emphasis equalizer lC included in each end, which can extend the length of the cable; OSFP-800G-ACCH can extends the length to 3m, 4m, and 5m while maintaining low latency and low power consumption of 1.5W per end.

Description

OSFP-800G-CU2H Compatible 2m (7ft) Twin-port 2x400Gb/s OSFP Finned Top to 2x400Gb/s OSFP Finned Top Passive Copper Cable

NADDOD OSFP-800G-CU2H is a 2x400Gb/s twin-port OSFP (Octal Small Formfactor Pluggable) Finned Top to 2x400Gb/s twin-port OSFP Finned Top Direct Attached Copper cable (DAC). 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. Using the Octal Small Formfactor Plug (OSFP) and containing eight high-speed electrical copper pairs, each operating at data rates of up to 100Gb/s. NADDOD’s cable solutions provide power-efficient connectivity enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.

Questions & Answers

Ask a Question

Why are there no NDR AOCs?

OSFPs are very large and heavy and the fiber breaks easily. A two-splitter cable will have three large transceiver ends. A four-splitter cable will have five transceivers. That would almost certainly make it easy to break the fiber during installation - especially for a 30 meter AOC.

What is the maximum transmission distance of the OSFP-800G-DACH cable?

The passive DAC can provide up to 3M.

We have some QM9700 NDR switches connected with original IB cables, if we use them together with your cables will there be any incompatibility problems?

NADDOD IB cables meet international standards, with good interoperability and compatibility, and are able to be paired together with the original cables.

I have ordered several cables from NADDOD to test on the NVIDIA 9790 switch, and I'm delighted to have received such high-quality high-speed cables here. The pricing was reasonable, and the delivery was fast.

The NADDOD technical team is highly professional, and their expertise has provided me with a new understanding of my network architecture. Finally, I purchased 800G cables from them to connect my NDR switch, and the connection is working well now.
