Deliver dependable 10 GbE transport over single-mode fiber with the AddOn SFPP-LR-AO. This TAA-compliant SFP+ transceiver is built for 10GBASE-LR deployments and uses an LC duplex interface, making it a strong fit for switch uplinks, backbone links, and other optical paths that need longer reach without changing the surrounding fiber architecture. For infrastructure teams, the advantage is straightforward: preserve the network design, replace only the optics, and keep the link profile aligned with enterprise standards. The LR specification is the right answer when multimode optics are no longer sufficient and you need a single-mode path that supports stable transport across longer distances. That makes this module useful for data center interconnects, campus aggregation, and standardized spare pools. Because it is positioned as a compatible AddOn replacement for Fujitsu SFPP-LR environments, it also helps reduce sourcing complexity. You get a module intended for practical interoperability, with the compliance profile procurement teams expect and the optical characteristics network teams need to keep critical links up.
