Verified by VIAVI OneAdvisor, the breakthrough deployment in West Palm Beach delivers carrier-grade performance without fiber’s delays, vulnerabilities, or spectrum constraints — and is ready to power 5G, 6G, AI, and quantum-enabled smart cities today.

WEST PALM BEACH, Fla.--(BUSINESS WIRE)--Apr. 14, 2026-- Tomorrow City USA Conference--X-lumin, the leading terrestrial free-space optical (FSO) communications company, today announced it has achieved bidirectional wireless optical data transmission at 400 Gbps full duplex — an industry first — across its commercially deployed laser communication system in West Palm Beach, Florida. Performance of its system, called “TeraLink,” was independently validated using a Viavi OneAdvisor 800 transport platform with a 400G transport module, confirming carrier-grade metrics that rival — and in several key dimensions exceed — those of buried fiber.

The system has been installed since October 2025, deployed in collaboration with Related Ross Real Estate, connecting the landmark luxury properties One Flagler and 360 Rosemary. Through X-lumin’s Preferred Partnership with Cisco, TeraLink utilized Cisco’s 8201 router and 400G OpenZR+ coherent optics, the verified results set a new benchmark for what wireless infrastructure can deliver:

• 400Gbps bandwidth
• 0.0243 millisecond latency
• 0.003 microsecond jitter
• 0.00384 frame loss ratio

Those are not lab numbers. They are live performance metrics from TeraLink in a deployed commercial system — a distinction that separates X-lumin’s announcement from prior laboratory demonstrations, and positions the technology squarely in the realm of critical infrastructure.

WHY THIS CHANGES THE CALCULUS ON CONNECTIVITY

Fiber remains a preferred standard for wireline capacity, but its real-world weaknesses are increasingly difficult to ignore. Permit timelines, municipal right-of-way negotiations, material procurement, trenching, and construction routinely stretch fiber deployment schedules to 18–36 months. Once buried, fiber is vulnerable: cable cuts from construction, theft of copper-sheathed lines, and flood-driven outages regularly knock out even ring-protected routes.

The September 2024 flooding in Houston illustrated the stakes starkly. Fiber rings — the redundancy architecture operators depend on — were simultaneously compromised by floodwater intrusion, leaving portions of the metro without service for weeks. When both sides of a ring share the same underground conduit path, ring topology offers theoretical resilience that can erase in hours.

Microwave, the traditional alternative for wireless backhaul, carries its own structural liabilities. Its spectral throughput ceiling has been largely reached at commercially viable frequencies. Licensing costs and spectrum scarcity impose hard constraints on deployment scale. And microwave’s latency and bandwidth characteristics are simply incompatible with the performance envelope demanded by AI inference workloads, autonomous systems, and emerging quantum networking overlays.

Laser communication changes all three equations simultaneously. X-lumin’s FSO links require no spectrum allocation, and can be installed in days rather than months. They are inherently immune to the physical vulnerabilities of buried fiber. And at 400 Gbps with sub-25-microsecond latency, they deliver the bandwidth and timing precision that next-generation applications require.

THE INFRASTRUCTURE LAYER FOR WHAT COMES NEXT

The global infrastructure stack is undergoing simultaneous stress tests: 5G densification is demanding ever-tighter backhaul SLAs; AI and AIoT workloads are collapsing the tolerance for latency variance; quantum key distribution networks require optical fidelity that copper and microwave cannot provide; and municipalities pursuing smart city mandates need a connectivity substrate that is high-performance, rapidly deployable and carries stronger resilience.

X-lumin’s 400 Gbps capability with 0.003 microsecond jitter meets the timing requirements of AI inference grids and real-time sensor fusion at the network edge. The license-free optical spectrum makes it a natural complement to — or primary bearer for — 5G small cell and macro-site backhaul. Its architecture is “FutureG” capable: as 6G air interfaces push toward terabit throughput and sub-millisecond end-to-end budgets, the optical backhaul tier will need to match. X-lumin is already there.

For multi-dwelling units, mixed-use towers, data centers, and enterprise campuses, the proposition is equally direct. X-lumin can deliver a gigabit-class, carrier-grade connection between buildings within days of a signed agreement — with zero trenching, zero spectrum fees, zero emissions, and a link budget that exceeds what most operators can provision over fiber in the same timeframe. True physical-layer redundancy, spatially diverse from traditional modes, becomes economically accessible for the first time.

QUOTES

“We intentionally designed TeraLink to be interoperable with existing telco infrastructure – it is a Layer-2 agnostic system, and is fiber-coupled for a fully optical solution. Without any O-E-O conversion it is able to support Quantum 2.0 technologies such as Quantum Key Distribution and Quantum Timing. Adding the terabyte bandwidth and low latency makes TeraLink foundational infrastructure for resilient future cities, AI, and datacenter interconnects.”

— John Stryjewski, PhD, CTO and Co-Founder, X-lumin

“Operators and cities have been waiting for a wireless alternative that carries exceptional performance and speed of deployment. X-lumin removes many of the pain points in existing networks and greenfield expansions. We can now walk into a conversation with a tower operator, a data center campus, or a municipality and offer terabit capacity, high availability, and a deployment timeline measured in days — with no spectrum license, no trench permit, and no single point of failure shared with their existing fiber network.”

TOMORROW CITY USA — PANEL CONTEXT

X-lumin will present this milestone at the Tomorrow City USA conference, where the company’s Chief Growth Officer, Zev Suissa, will join the panel on Full Stack AI and AIoT Infrastructure for Cities. Panelists include Jumbi Edulbehram of NVIDIA and John Lockhart of SHI International, moderated by Ali Asad Hasan, former AWS Global Smart City Lead. The panel will address how municipalities can architect the physical and digital infrastructure layers necessary to support AI-native city operations — from edge compute and IoT sensor networks to the high-throughput, low-latency backhaul that binds them together.
