25G SFP28 Direct Attach module, 3 meters — buy in Tashkent

The 25G SFP28 Direct Attach module from Pixietech with a 3-meter cable length is designed for high-speed connection of servers, switches, and network cards within a server rack or between adjacent racks. The passive copper DAC cable provides data transmission at 25 Gbit/s without using optics, which reduces connection cost and simplifies installation. The 3-meter length provides additional flexibility in routing cables between racks located side by side.

Advantages

25 Gbit/s speed: the modern standard for server and hyperconverged environments
3-meter length: allows connecting equipment in adjacent racks without surplus extra length
Passive type: no active components — minimal heat dissipation and high reliability
Standard SFP28 form factor: wide compatibility with server platforms and switches
Low latency: a direct copper connection provides minimal latency compared to optics
1-year warranty from Pixietech

Applications

Data centers and server halls: connections between racks within a single row
Corporate networks: combining server nodes into high-performance segments
Cloud platforms: a transport layer between compute and network units
Storage systems: connecting high-speed storage to server clusters

Frequently asked questions

How does a passive DAC cable differ from an active one?

A passive cable does not contain built-in electronics for signal amplification, which makes it cheaper and more reliable over short distances; active cables are used over greater lengths where signal attenuation is unacceptable.

Can the module be used together with equipment from other brands?

The SFP28 form factor is standardized, and most switches and cards support DAC cables from third-party manufacturers; it is better to check compatibility with the specific platform in advance.

Is there a difference between a 2 m and 3 m DAC in terms of signal characteristics?

At both lengths, the passive copper cable provides stable 25 Gbit/s transmission without loss of quality — the only difference is the physical length.
