Aruba S4J91A 25G CSR SFP28 LC 300 meters Multimode - Transceiver

The Aruba/HPE Networking 25G CSR SFP28 LC 300m Multimode Transceiver (S4J91A) is an optical module designed to expand the bandwidth of compatible networking equipment. It provides a data link with transfer rates up to 25 Gbit/s. Administrators use this component to increase capacity within data centres without replacing existing switching platforms. The unit plugs into an available cage on a supported device to connect core network segments and servers.

The module uses multimode fibre cabling and requires a standard LC connector to terminate the link. Operating under the 25GBase-CSR standard, it supports short- to medium-reach deployments. It has a maximum transmission range of 300 metres, which is sufficient for typical inter-rack bridging. The modular format allows for port speed upgrades while keeping current chassis hardware in place.

• Single optical fibre port for point-to-point network links.
• Uses the SFP28 interface for compatibility with 25G switch slots.
• Dimensions: 18 mm width, 127 mm depth, and 13 mm height.
• Weight: 49.9 grams.
