Maintain high-speed connectivity across longer fiber spans with the Ubiquiti UACC-OM-SM-10G-S-20. This 20-pack of 10 Gbps bidirectional single-mode optical modules is built for simplex transport over single-mode fiber, giving network teams a clean way to extend uplinks without adding unnecessary complexity. Each module supports 10 Gbps throughput and reaches up to 10 km, making it well suited for campus backbones, building-to-building links, and aggregation paths where copper is no longer the right answer. The simplex design reduces fiber count requirements, which can simplify cable plant planning and lower deployment friction in dense environments. For teams standardizing on Ubiquiti infrastructure, the multi-pack format helps keep spares on hand and supports consistent rollouts across multiple switches or sites. It is a straightforward choice when link distance, fiber efficiency, and predictable 10 GbE performance matter more than feature bloat. This is the kind of module you buy when uptime, scale, and clean physical design matter.
