Fiber-optic networks are fast becoming critical national infrastructure, replacing aging copper to meet soaring data demands, close the digital divide, and safeguard vital services like aviation.

The explosion of data from artificial intelligence (AI), cloud computing, and connected devices is straining networks built with vulnerable, outdated copper. Current networks leave millions in rural America without access to reliable, high-speed internet.
As bandwidth requirements grow and low-latency connections become essential for healthcare, education, and industry, fiber’s unmatched ability to move massive amounts of data quickly and efficiently makes it indispensable. Expanding access to fiber optics is about more than speed; it’s about economic resilience, public safety, and social equity.
Case Study: Critical Role of Fiber Technology in Enhancing Aviation Safety
A key example of the importance of fiber in network connectivity is demonstrated at Newark. After two outages this spring, the Federal Aviation Administration (FAA) is urgently overhauling infrastructure at Newark Liberty International Airport to address critical safety concerns.
On May 9, 2025, a 90-second radar and communications blackout threatened to disrupt air traffic in one of the busiest airway corridors in the country. Ten days later, another, briefer outage underscored the weaknesses of the Philadelphia TRACON facility, which manages Newark’s airspace and exposed dangerous vulnerabilities. The disruptions caused over 156,000 passenger delays at Newark.
These outages were caused by aging copper cables.1,2
The FAA has responded by replacing copper connections with fiber optics, a $42.5 billion modernization of national infrastructure extending into aviation. The corrective measures included establishing high-bandwidth fiber links between facilities in New York and Philadelphia and adding three new fiber-optic lines to enhance redundancy and speed.
A dedicated Standard Terminal Automation Replacement System (STARS) hub was also established in Philadelphia to reduce reliance on New York's overloaded system.1,2
Sean Duffy, Secretary for Transportation, has framed the Newark upgrades as a stopgap in a much larger push to overhaul outdated technology nationwide, warning of similar risks elsewhere. He emphasized fiber's importance in preventing catastrophic failures and enabling crucial real-time data flows.3
He announced the completion of the work on July 3, saying, "This marks a critical milestone in our unprecedented effort to make flying safer and more efficient." 3
Accelerating Access: BEAD Funding and Public-Private Deployment Models
The transition of fiber into a critical, nationwide infrastructure has been catalyzed by public investment. The Broadband Equity, Access, and Deployment (BEAD) Program, with a budget of $42.45 billion, is the largest federal commitment to bridging the digital divide across America.
Funding is being targeted to communities without reliable 100/20 Mbps service, with Texas receiving the largest allocation at $3.3 billion, followed by California, Missouri, Michigan, and North Carolina. States are required to submit deployment plans within 180 days, which include processes to correct coverage maps.4,5
These BEAD funds also encourage private investment opportunities. For instance, AT&T has utilized these funds to launch "Gigapower," a joint venture with BlackRock aimed at connecting 1.5 million locations outside AT&T’s traditional footprint.
Industry experts say fiber’s longevity and scalability make it far more cost-effective in the long run than stopgap technologies like fixed wireless or satellite.4
Regional Innovators: Metronet, Quantum Fiber, and Technical Leapfrogging
Across the country, regional providers are showing how flexible fiber deployment can be. In Downers Grove, Illinois, Metronet is speeding up urban and suburban rollouts by micro-trenching fiber into existing utility conduits, minimizing disruption and avoiding protracted negotiations over street repairs.6
Meanwhile, Quantum Fiber targets multifamily and master-planned communities by retrofitting older properties using riser shafts and minimally invasive techniques. Their strategy highlights the technical advantages of fiber. XGS-PON technology is delivering symmetrical speeds of up to eight gigabits per second without needing to replace existing fiber.7
The integration of WiFi 7 also allows for whole-home coverage with fewer mesh nodes. With a reliability rate of 99.9 percent, based on network uptime, it is critical for telework and telehealth. These initiatives effectively tackle the challenge of excavation costs by leveraging existing infrastructure.7
Persistent Challenges: Labor, Materials, and Regulatory Friction
Despite the progress made in fiber rollout, there are still challenges in the way of its successful, nationwide integration. One of the most pressing challenges is the shortage of skilled workers. The United States faces a deficit of 3,000 air traffic controllers, a crisis affecting aviation fiber upgrades.2-4
The broadband sector struggles to find trained fiber splicers, directional drill operators, and network engineers. While training programs are available, they take time to produce qualified personnel.
For example, the Philadelphia TRACON currently has 22 controllers in training, but they will not be fully certified until late 2025. This workforce scarcity drives labor costs and extends project timelines, particularly for smaller providers working with the BEAD program.3,4
The threat of copper theft also poses risks to existing infrastructure during this transition. Rising copper prices have led to thousands of theft incidents, resulting in service disruptions that endanger public safety, healthcare, and education.
And in remote areas, the economics of last-mile fiber connections, often exceeding $20,000 per home, remain difficult. Many experts see hybrid models combining fiber middle-mile networks with fixed wireless last-mile solutions as a viable compromise. 4,8,9

Conclusion: Weaving a More Connected and Equitable Fabric
The U.S. now faces a clear choice: continue treating fiber as optional and risk deepening inequality and vulnerability, or recognize it as critical infrastructure, as fundamental as roads and electricity.
The outages at Newark were a stark reminder of the risks of inaction. But the BEAD program offers an unprecedented opportunity to build a more connected and resilient society, if workforce shortages, regulatory bottlenecks, and funding gaps can be overcome.
Expanding fiber access won’t just deliver faster internet; it will unlock new opportunities in AI-driven industries, expand telehealth and education in rural areas, and inject competition into markets long dominated by monopolies. What was once a premium technology is now central to ensuring an inclusive digital future.
