Generic Compatible 800G QSFP-DD DAC Twinax Cable (1-2m, Passive, QSFP-DD to QSFP-DD, 26-30AWG)
The 800G QSFP-DD passive direct-attach Twinax cable is a cost-effective alternative to AOC cables in 800 Gigabit Ethernet connectivity. The DAC cable adopts the standard QSFP-DD form factor and complies with MSA specifications. The Twinax copper cable has 8 lanes of 100Gbps, including 16 copper pairs, and each pair supports 100Gbps data transmission. The DAC cable operates in the case temperature range of 0 to +70ºC and complies with IEEE802.3ck. The cable is ideal for data center short-distance data transmission applications.

Questions & Answers
What does QSFP-DD means?
QSFP-DD means Quad small form factor pluggable double density, which is also known as QSFP56-DD. It is fully compatible with IEEE802.3bs and QSFP-DD MSA. When you compare this module to a standard QSFP28 module, the “double density” means that it allows twice as many high-speed electrical interfaces.
How do I select the appropriate 800G QSFP-DD DAC?
Consider the necessary length, signal quality, compatibility with your equipment, thermal performance, and price.
Can I connect earlier QSFP connectors to an 800G QSFP-DD DAC?
No, 800G QSFP-DD direct attach cables are intended only for the 800G standard and QSFP-DD connections.
What safety precautions should be taken?
- Handle the cords with care to avoid damage.
- Avoid excessive bending and twisting.
- Ensure appropriate grounding.
