Build long-reach 10 GbE links without overbuying optics for the job. This Extreme Networks 8-pack of LR SFP+ transceivers is designed for single-mode fiber deployments that need dependable reach up to 10 km. The LC connector keeps integration straightforward in standard fiber environments, while the 8-pack format helps teams deploy consistently across multiple switches, closets, or sites. For infrastructure teams, the value is in alignment: the right reach, the right connector, and enough units to support a coordinated rollout. LR optics are a practical choice for campus backbones, building-to-building runs, and access-to-distribution uplinks where SR optics fall short and ER optics would add unnecessary cost. The extended-temperature note makes this package especially relevant for environments where equipment rooms are not perfectly controlled. If you are refreshing a distributed network or stocking spares for a standard 10 GbE platform, this pack reduces procurement friction and keeps your optics inventory consistent across the fleet.
