The Pixietech PXT-QSFP28+DA-2 module is a passive 100-gigabit direct-attach DAC cable in the QSFP28 form factor with a length of 2 meters. It provides a high-speed 100G connection of two devices within one or adjacent racks without using optical transceivers. The solution is suitable for data centers where an economical and reliable way to implement 100-gigabit links is required.

Advantages

100 Gbit/s of throughput meets the requirements of modern data centers and high-load networks
A length of 2 meters provides flexibility when connecting devices in different rack positions or in adjacent cabinets
The passive design reduces heat dissipation and increases reliability compared to active cables
The cost is lower than a pair of 100G optical transceivers at the same performance
Plug-and-play without additional configuration
1-year warranty from the manufacturer

Applications

Data centers: connecting servers, switches, and storage in adjacent rack positions
Corporate networks: high-speed uplinks between core network equipment
Virtualization and clusters: minimal latency between compute cluster nodes
Telecommunications companies: 100G junctions between platforms in a single technical room

Frequently asked questions

How does the PXT-QSFP28+DA-2 differ from the DA-1 version?

The only difference is the cable length: the DA-2 has a length of 2 meters versus 1 meter for the DA-1, which provides more flexibility in equipment placement.

Does the cable work with equipment that supports only 40G on a QSFP+ port?

QSFP28 and QSFP+ are different standards; QSFP+ DAC cables are used for 40G, while the PXT-QSFP28+DA-2 is intended specifically for 100G QSFP28 ports.

Is splitting 100G into 4x25G supported with this cable?

This cable is a standard QSFP28 DAC, not a breakout cable; specialized breakout variants are used to split 100G into 4x25G.
