DAC-400G-QDD-4*QSFP
from $89.00
MSA Compatible 400G to 4x100G DAC Cable (1-3m, Passive, QSFP56-DD to QSFP56, 26 – 30AWG)
MSA Compatible 400G to 4x100G DAC Cable (1-3m, Passive, QSFP56-DD to QSFP56, 26 – 30AWG)
The DAC breakout cable assemblies are suitable for high-density 4 x 100G Ethernet solutions. The hot pluggable QSFP-DD form factor and QSFP56 form factors provide 400G transmission from a 400GbE connector on one side to four separate 100GbE connectors on the other four sides. The passive direct attach breakout cable complies with QSFP-DD MSA and IEEE802.3cd standards. QSFP-DD to 4x QSFP56 cable assemblies that connect data signals from 16 pairs on the single QSFP-DD end to the dual pairs on each of the QSFP56 multiport ends. The length of QSFP-DD to QSFP56 DAC is 1m, 2m, and 3m, which is good for SAN, HPCs, and AI enterprise networks.

Questions & Answers
What are the key use cases for this breakout cable?
This direct attach cable is suited for data center fabric connectivity, such as migration paths from 100G to 400G infrastructure, high-density server connections, network disaggregation, and scale-out designs.
What is the maximum transmission of 400G QSFP-DD to QSFP56 DAC?
The direct attach cable cable allows for a maximum link length of 3 meters with 26AWG cable. The available lengths are 1m, 2m, 3m.
AOCs vs. DAC cables: which is better?
AOCs and DAC cables are both good high-speed cables, but each has certain advantages. DAC cables have various benefits over AOCs:
Cost-Effective: Their simpler, copper-based structure makes them cheaper to make.
Lower power consumption: DACs enable large-scale data centre and network deployments save electricity.
Durability and Simplicity: DAC cables include fewer parts and no optical transceivers, making them more robust than AOCs. DACs are trusted for short-range connectivity.
