CHICAGO – November 02, 2026 -- McKay Brothers has purchased Relativity Networks' ChronoCore anti-resonant hollow-core fiber for commercial deployment in its New Jersey networks, starting a partnership to link key financial market venues and data center projects.
McKay offers dedicated fiber IRUs and 10 to 400 Gbps services
McKay will sell long-term indefeasible rights of use (IRUs) on dedicated hollow-core fiber pairs. It will also offer traditional connectivity services from 10 Gbps to 400 Gbps. The initial focus is New Jersey, with expansion into other markets planned.
The network design includes branches for high-capacity, low-latency links to data center projects near key financial corridors, where customers are building AI inference and training infrastructure.
ChronoCore's low dispersion cuts regeneration, power and real estate needs
According to the companies, ChronoCore's low dispersion and optimized route design support more capacity and longer reach with fewer active optical components. Less intermediate regeneration lowers power and real estate requirements. McKay is designing the networks to reduce the total cost of carrying data, deliver lower latency and make both benefits available to all market participants.
Relativity says its patented fiber carries data roughly 47 percent faster than conventional glass fiber.
McKay cites U.S. patents and Prysmian production in supplier choice
McKay COO Tim Boyle said the company has worked with successive generations of hollow-core fiber for nearly a decade. He said IP provenance and security of supply matter alongside performance for critical U.S. market infrastructure. He pointed to Relativity's U.S. patent portfolio and roadmap, which rely on Prysmian's proprietary fiber and cable production.
Relativity Founder and CEO Jason Eichenholz called McKay's purchase an important commercial milestone for the company.
Power and real estate availability drive compute siting
Boyle said the intersection of power availability and real estate determines where compute gets built. McKay aims to connect more of those sites to the existing financial ecosystem. Customers would gain more choice over where they access live data and run applications, including AI inference, and synchronicity between market centers would improve.
