25G SFP28 Direct Attach module, 2 meters — buy in Tashkent

The 25G SFP28 Direct Attach module from Pixietech with a 2-meter cable length is a compact and reliable solution for high-speed connection of servers and switches within a rack or between adjacent racks. The passive copper DAC cable transmits data at 25 Gbit/s without additional optical components, making it an economical alternative to optical transceivers at short distances. It is optimal for data centers, server rooms, and high-load network nodes where minimal latency and low power consumption are important.

Advantages

25 Gbit/s speed: provides high throughput for modern server applications and hypervisors
Passive design: the copper DAC cable requires no active electronics — less heat dissipation and higher reliability
2-meter length: a convenient size for connections within a single rack or between closely standing racks
Cost savings: significantly cheaper than a pair of optical transceivers with a patch cord at comparable speed
Support for the standard SFP28 form factor: compatible with a wide range of switches and network cards
1-year warranty: Pixietech takes responsibility for product quality

Applications

Data centers: connection between ToR switches and server chassis
Enterprise server rooms: combining servers into high-performance clusters
Cloud and virtualized environments: a reliable transport layer for hypervisors
Telecommunications nodes: compact inter-unit connections in operator-grade racks

Frequently asked questions

Is the module compatible with equipment from other manufacturers?

The SFP28 form factor is an industry standard, and most modern switches and network cards support passive DAC cables from third-party manufacturers; however, before purchasing, it is recommended to check compatibility with the specific equipment model.

Are additional drivers or settings needed for connection?

The passive DAC cable is detected by the equipment automatically and requires no driver installation or manual configuration.

Is the cable suitable for use outside the rack, for example between different rooms?

No, the 2-meter length is designed for connections within a single rack; for inter-room or inter-floor lines, use optical transceivers with the appropriate range.
