Keep high-speed links stable across distances where standard optics fall short. This Axiom-compatible 100GBASE-ZR4 QSFP28 transceiver is designed for single-mode fiber deployments that need 100 GbE performance over long spans, with support for up to 80 km and LC connectivity. The 1310 nm wavelength is suited to long-reach optical transport, making it a strong fit for metro aggregation, inter-building backbones, and carrier-adjacent environments. For infrastructure teams, the value is in preserving throughput without redesigning the network around shorter-reach optics. ZR4-class reach helps reduce the need for intermediate regeneration in the right topology, while the QSFP28 form factor keeps density high in modern switching and routing platforms. ALCATEL compatibility also makes this module practical for organizations maintaining mixed-vendor environments or extending the life of existing optical infrastructure. Choose this transceiver when the link is too important for compromise: long-distance transport, predictable optical performance, and a deployment profile aligned to enterprise and service-provider requirements. It is a focused component for teams that need distance, density, and interoperability in one module.
