Keep 1-Gig multimode links consistent with an HP-compatible SX SFP designed for enterprise switching. This AddOn transceiver uses an LC duplex connector and supports 1000BASE-SX over multimode fiber, giving infrastructure teams a direct-fit option for short-range optical connectivity. With support for up to 1,000 m, this module extends the practical reach of 1-Gig fiber links across campus networks, wiring closets, and adjacent buildings where copper no longer fits the design. TAA compliance helps satisfy procurement requirements in public-sector and regulated environments, while the AddOn compatibility profile supports straightforward replacement in HP-based deployments. For teams that need a reliable optical module without overbuying capacity, this SFP keeps the focus on the essentials: compatibility, distance, and clean integration into existing fiber infrastructure. It is a practical choice for maintaining service continuity and standardizing optics across a mixed enterprise network.
