800G QSFP-DD & OSFP Direct Attach Copper (DAC) Cables

800G DAC cable is a high-performance, low-power direct-attach copper cable for short-distance, high-speed data transmission in data centers.

The 800G DAC cable is OSFP MSA and IEEE 802.3ck compliant and supports data rates up to 800Gbps.The cables typically utilize 16 pairs of high-speed copper wires with a data rate of 106.25Gbps per pair.
Cable lengths typically range from 0.5 meters to 3 meters, depending on the application scenario.

FAQ About 800G DAC Cable

What is an 800G DAC cable?

An 800G DAC (Direct Attach Copper) cable is a high-speed, cost-effective, and low-latency interconnect solution used to transmit data at 800 Gigabits per second over short distances. It features integrated transceivers at both ends and connects directly into compatible ports, typically used in data centers, high-performance computing (HPC), and cloud infrastructure.

What's the 800G DAC cable MOQ?

We can accept small quantity,even 1pc. MOQ:1pc

What are the benefits of using 800G DAC cables?

Key benefits include:

  • Low power consumption (passive cables don’t require power)

  • High reliability due to fewer failure points

  • Cost-effective for short-range connections

  • Minimal latency, ideal for time-sensitive applications

  • Plug-and-play simplicity

What are the common types of 800G DAC cables?

Common types include:

  • 800G QSFP-DD to QSFP-DD DAC cables

  • 800G OSFP to OSFP DAC cables

  • Breakout DAC cables, such as 800G QSFP-DD to 2x400G QSFP-DD or 800G to 8x100G options

These support different switch and device port types for flexible deployment.

What is the typical maximum length of an 800G DAC cable?

800G DAC cables typically support lengths up to 0.5 to 3 meters, depending on the gauge and signal integrity requirements. For longer distances, Active DAC (AOC) or optical transceivers are recommended.

How do I choose the right 800G DAC cable?

Consider the following:

  • Port type (QSFP-DD, OSFP)

  • Required cable length

  • Passive vs. active cable type

  • Application (standard or breakout)

  • Compatibility with switches/servers
