HPE 455886-B21 10GB LR SFP+ server accessory

HPE 10GB LR SFP+ module

The HPE 455886-B21 is a 10GB long-range SFP+ transceiver designed for Hewlett Packard Enterprise server environments. It provides optical connectivity for high-speed data links in compatible blade or rack systems. This accessory targets administrators extending fibre connections across longer distances within a data centre. The module carries the Hewlett Packard Enterprise brand and was first listed by the manufacturer in 2012.

Compatibility check before ordering

Verify that your HPE blade or rack chassis accepts SFP+ form-factor optics and supports long-range 10GB operation. Confirm the switch or interconnect module firmware recognises this part number to avoid link negotiation issues. Ensure the fibre patch cables match the required connector polish and core size for the intended run length. Cross-reference the server accessory matrix for the specific enclosure model in use.

Upgrade scope and when it applies

This transceiver replaces an existing short-range or failed SFP+ optic when the link distance exceeds the shorter reach specification. It upgrades a copper direct-attach cable deployment to optical fibre for immunity to electromagnetic interference. The jump is worth it when the physical topology demands runs beyond the limits of SR optics or passive copper. Buyers needing higher bandwidth than 10GB or a different wavelength should evaluate alternative modules.
