OEM and customized SFP28 extension cable solutions are available for network equipment manufacturers, system integrators, distributors, and data center projects. Customization may include cable length, connector configuration, labeling, packaging, branding, and other project-specific requirements.

For larger deployments, compatibility with the target switches, servers, and existing SFP28 cable assemblies can be evaluated before production. Customers can provide the required length, equipment models, quantity, and installation environment to develop a suitable configuration.

What is the difference between this cable and a standard SFP28 DAC?

A standard SFP28 DAC normally has an SFP28 male connector at both ends and directly connects two SFP28 ports. This product has an SFP28 male connector on one end and an SFP28 cage female interface on the other, allowing it to function as an extension for an existing SFP28 connection.

Can I combine this extender with another SFP28 DAC?

Yes, the extender is designed to be used with an existing compatible SFP28 connection. However, combining multiple cable segments increases the total electrical channel length and insertion loss. The complete link should remain within the signal-integrity and reach limitations of the connected equipment.

Why choose a passive copper extender instead of an active solution?

A passive copper extension does not require active optical components or signal conversion, which helps minimize power consumption, cost, and system complexity. It is particularly suitable for short-distance connections inside racks or between closely positioned network devices.

Is the cable compatible with different network equipment brands?

The cable is designed around SFP28 MSA and relevant SFF specifications, making it suitable for use with compatible equipment from multiple manufacturers. However, actual interoperability can depend on the host platform and its support for the specific cable configuration, so equipment compatibility should be verified before deployment.

What length should I select?

Available lengths range from 0.3m to 3m. The recommended choice is generally the shortest length that provides sufficient routing flexibility. Using an appropriately sized cable can help maintain cleaner rack layouts and avoid unnecessary cable congestion.
