WHY CHOOSE THIS PRODUCT?

• Organizations choose 813874-B21 when a compatible HPE SFP+ interface needs 10GbE connectivity over RJ45 copper rather than optical fiber. Its 30m reach over Cat 6a/7, SFP+ form factor and 10GBase-T design make it particularly useful for short-distance server, storage and switch connections. The practical procurement advantage is the ability to leverage existing structured copper cabling while upgrading supported SFP+ ports to 10GbE, reducing the need for an immediate fiber infrastructure change. For lifecycle programs, it is a targeted replacement and expansion component where platform compatibility and switch release-note support should be confirmed before deployment. HPE specifically advises checking switch release notes for the required software version and notes that some switches limit the number of these transceivers that can be installed.
