Maintain dependable 10 GbE connectivity across longer fiber runs with the AddOn SFP-10G-LR-AO transceiver. Designed for 10GBASE-LR environments, it delivers single-mode fiber performance through an LC duplex interface, making it a practical fit for server uplinks, aggregation switches, and inter-rack connections that need consistent optical reach. This module is positioned for teams standardizing on Cisco-compatible optics while keeping procurement aligned with TAA requirements. That matters in public sector, regulated, and enterprise environments where approved sourcing and predictable interoperability are part of the buying decision. The LR profile is the right choice when short-reach optics are not enough and you need a cleaner path across data center aisles, between closets, or into campus distribution layers. For infrastructure teams, the value is in reducing ambiguity. You get a clearly defined 10 GbE optical path, single-mode support, and the connector style expected in modern fiber plant designs. It is a straightforward way to extend capacity without changing the network architecture or overbuying on more expensive transport options. When the requirement is stable long-distance 10 GbE, this module keeps the design simple and the link budget predictable.
