Specifications
Arista Networks CAB-D-D-400-2.5 Compatible 400G QSFP-DD DAC Twinax Cable (2.5-meter, Passive, QSFP-DD to QSFP-DD, 28AWG)

The 400G QSFP-DD DAC primarily enables high-bandwidth 400G links and supports 400G Ethernet rate. It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. 400G QSFP-DD DAC cables are suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between QSFP-400G ports of switches/routers within racks and across adjacent racks. FS currently offers passive copper cables in lengths of 0.5, 1, 1.5, 2, 2.5, and 3 meters.

Product Highlights
High Performance 400G QSFP-DD DAC

400G QSFP-DD DAC is the most power-efficient connectivity solution for short distance interconnects, because it is passive and has the characteristics of high reliability, low insertion loss and the lowest latency.

Arista High Performance 400G QSFP-DD DAC

Superior Workmanship of Direct Attach Copper Cable
Arista Foam Skin Technology
Foam Skin Technology

The special foam skin technology makes DAC higher foam degree, higher flexibility and smaller bending radius. Ensure stable transmission performance.

EMC Shielding

Electromagnetic shielding keeps the low crosstalk and high signal integrity, which ensures consistent transmission.

EMC Shielding
Arista Superior Insertion Loss
Superior Insertion Loss

Insertion loss is 10% lower than the industry average. Lower insertion loss, reducing the loss of optical power caused by the optical devices.

High-Order Modulation PAM4

400G DAC adopts 8x 50G PAM4 modulation. Its transmission efficiency is doubled compared to the NRZ signal, effectively reducing costs.

  • A:

    No, it can’t be used in the stack port of your device. FS DAC & AOC can only be used in the business port of the switch to achieve virtual stacking, but can not be used in the stack port to achieve physical stacking. The stacking through the stack port of device belongs to physical stacking which needs a specific stacking cable, and it is under development for now. By E***n on 24/11/2020
