Move 1 GbE traffic across multimode fiber with a compact SFP transceiver designed for short-range optical links. HPE R9D16A uses an LC connector and SX optics to support dependable connectivity over OM2 MMF, making it a strong fit for access-layer uplinks and nearby building connections. This module is a practical choice when copper is not enough and fiber is the right medium for the job. The 500 m reach gives network teams room to connect switches across closets, floors, or adjacent spaces without overbuilding the link. Its SFP form factor keeps deployment simple in compatible HPE networking hardware, while the optical design helps maintain signal integrity in structured cabling environments. For organizations that value predictable performance and clean cable management, a multimode fiber transceiver is often the right upgrade path. It supports the kind of short-distance backbone links that keep enterprise networks organized, serviceable, and ready for growth.
