25G SFP28 DAC cable (Passive Direct Attach Copper cable) 1m
The 25G SFP28 DAC cable 1m is a short passive copper cable that enables data transmission of up to 25 Gbps over a distance of 1 meter. Compatibility with SFP28 MSA standard ensures easy integration with any network devices. Its simple installation and low cost make it an excellent choice for efficient short-distance data transmission in server rooms or data centers. It is a lower-cost alternative to fiber optic inserts over shorter distances of several meters.
Each end of the DAC cable is individually encoded before shipment, making it possible to connecting devices from different suppliers.
Self-coding under different manufacturers is made possible by the LightBoard programmer (last photo), sold separately.
If the DAC cables will be installed in a server, please select the manufacturer of the network card, not the server, on your order.

DAC 25G SFP28 cable 1m
The DAC cable 25G SFP28 1m is an efficient and cost-effective solution for short-distance data transmission. It is ideal for use in modern data centers and server rooms. This passive copper cable offers reliable data transfer at speeds of up to 25 Gbps over a distance of 1m. Our range of DAC 25G cables also includes lengths from 1m to 5m.
Direct Attach Copper (DAC) technology means a direct connection without the need for optical signal conversion. In other words, data transfer is carried out via an electrical signal over copper cable between two QSFP28 modules. This enables a significant reduction in installation costs, and also minimizes transmission delays compared to fiber optic solutions. In addition, the lack of need to use lasers for optical transmission translates into significant energy savings.
Compatibility with the SFP28 MSA standard ensures full integration with a wide range of network devices, enabling easy and fast deployment.
Note: Cable not compatible with HP's Blade Series (B21) devices
