The Pixietech PXT-QSFP28+DA-3 is a passive 100 Gbit/s DAC cable in the QSFP28 form factor with a length of 3 meters for direct copper connection of network equipment. The maximum length in the DA series allows connecting devices located in different racks or remote positions of a single mounting row. The cable is suitable for high-load data center networks where an economical alternative to expensive 100G optical transceivers is needed.

Advantages

100 Gbit/s data transfer speed for the most demanding applications and workloads
A length of 3 meters provides the greatest coverage in the series, allowing connection of devices in different racks
Passive copper design: high reliability and minimal heat dissipation
Significant savings compared to 100G optical transceivers and patch cords
Easy connection to standard QSFP28 ports without additional configuration
1-year warranty from Pixietech

Applications

Data centers: connecting equipment in adjacent racks without using optics
High-performance computing: inter-node connections with minimal latency in HPC clusters
Corporate network cores: 100G uplinks between aggregation and core switches
Cloud platforms: connecting servers and storage in hyperconverged infrastructures

Frequently asked questions

Why is a passive DAC, rather than an active one, used for a length of 3 meters?

Passive DAC cables operate reliably over distances of up to 3-5 meters without additional amplifiers, providing low heat dissipation and high reliability at a lower cost.

Is the cable compatible with switches from Cisco, Juniper, Arista, and other manufacturers?

The cable uses the standard QSFP28 form factor; compatibility depends on the specific equipment model — check with SAT Solutions specialists.

Can the DA-3 be used as a 100G-to-4x25G breakout cable?

No, this is a standard QSFP28-to-QSFP28 cable; splitting requires a special breakout variant with QSFP28 on one end and four SFP28 on the other.
