Keep long-reach 10G links predictable with this SFP+ LR optical transceiver from Zyxel. Designed for single-mode fiber, it operates at 1310 nm and supports distances up to 10 km, making it a strong fit for campus backbones, building-to-building runs, and data center interconnects where multimode optics fall short. The LC connector aligns with standard enterprise fiber infrastructure, while the SFP+ form factor preserves switch port density and simplifies deployment in mixed environments. For teams planning around reach, signal integrity, and consistent interoperability, LR optics remain the right choice when the network spans more than a rack or row. This module is built for infrastructure that needs more than basic connectivity. It supports the kind of long-haul 10G transport that keeps aggregation layers, distribution switches, and remote closets connected without forcing design compromises. When the cost of a link failure is higher than the cost of the optic, LR is the safer specification.
