Move 100 GbE traffic across longer fiber spans with a QSFP28 optic designed for ZR4-class transport. This module is built for deployments where reach, compliance, and interoperability are part of the buying decision, not afterthoughts. In federal and regulated environments, that matters. The ZR4 design supports long-distance optical connectivity while keeping the footprint compact enough for dense switching platforms. For teams extending backbone links between buildings, campuses, or regional facilities, it offers a cleaner path than adding intermediate aggregation points or reworking the fiber plan. The result is simpler transport architecture with fewer moving parts. As a TAA-compliant AddOn Networks compatible optic, it aligns with procurement requirements that often rule out lower-cost alternatives. That makes it a strong fit for public sector and enterprise infrastructure teams that need a module they can standardize on. When the network depends on long-reach 100G links, the right optic is not just a component — it is part of the control plane for uptime, compliance, and operational consistency.
