Keep high-density Ethernet links moving across multimode fiber with the HPE Aruba R0M48A 50G SFP56 SR transceiver. Built for short-reach 50 GbE connectivity, it uses an LC duplex interface and is rated for up to 100 m over MMF, making it a strong fit for top-of-rack switching, leaf-spine fabrics, and server uplinks where port density and signal integrity matter. This module is designed for environments that need more bandwidth without moving to a more expensive long-reach optical tier. The SFP56 form factor supports compact switch designs, while the SR optical profile keeps cabling straightforward in structured multimode runs. For infrastructure teams standardizing on Aruba networking, it provides a clean path to higher-speed links without changing the physical fiber plant. Choose this transceiver when you need short-reach performance, predictable interoperability within supported Aruba environments, and a compact optics footprint that preserves switch density. It is a practical fit for enterprise data centers that value consistent link behavior and efficient use of rack space.
