Keep 10 GbE links stable across longer fiber runs with this 10GBASE-BXD SFP+ optics module. Designed for single-mode fiber and rated for 10 km, it supports deployments where copper is too short and multimode optics do not reach far enough. The BXD bidirectional design helps simplify long-distance connectivity while preserving the compact SFP+ footprint teams expect in dense switching environments. For infrastructure teams standardizing on Arista-compatible optics, this module offers a practical path to extend server, switch, and aggregation connections without changing the physical layer architecture. It is well suited to campus backbones, building-to-building links, and remote equipment rooms where predictable optical performance matters. The 10 GbE data rate keeps throughput aligned with modern access and aggregation demands, while the single-mode design supports the distance and signal integrity required for production networks. Choose this module when the link budget matters and the deployment needs a clean, purpose-built optic rather than a generic short-reach part. It is a focused fit for environments that value compatibility, reach, and disciplined network design.
