SFP28 Direct Attach Cables

25GBase Small Form Factor Pluggable Transceivers

SFP28 DAC are hot-pluggable cables used for 25Gb data transmission.  The term “SFP” stands for Small Form Factor Pluggable, and utilizes a single transmit and single receive within the SFP28 connectors.  These cables utilize copper COAX wiring and are an ideal low-cost option for short reach applications.  SFP28 DAC are ideal for high-speed transmission in data centers, cloud computing, and hyper-scale transmission and are compliant with RoHS, IEEE, and MSA standards.

Compatible Manufacturers

GigaTech Products has been a leading manufacturer of compatible transceivers and cables for over a decade, bringing customers affordable alternatives to Cisco, Juniper, Brocade, Dell, and HP original items. With the ability to custom code transceivers and direct attach network cables, GigaTech can provide compatible alternatives for most lesser-known brands, while ensuring 100% compatibility

Optical Transceiver Standards & Compliance​

Never Sourced. Never Recycled.

All components in GigaTech Product optics are manufactured under the same roof and represent the gold standard for reliability and consistency in performance. This vertical manufacture chain allows GigaTech to avoid unnecessary variances in transceiver casing or laser quality often found with online resellers who source their components from an ever changing vendor list. The transceiver is guaranteed to be built from A-Stock never used components overseen by GigaTech Products,

Rigorous Testing & Standards Compliance

The quality and standards of our hardware is one the base foundations of GigaTech Products. All of our components comply with MSA (Multi-Source Agreement) output standards and, in many cases, excel beyond those certification standards. Every transceiver we produce is tested on active network devices to ensure they comply with OEM equipment and are verified to be plug-and-play and do not require work arounds.
