Federal infrastructure investment tied to the Infrastructure Investment and Jobs Act is pushing billions of dollars into transportation, utility, and public safety networks, and every project set to receive federal funding comes with a domestic sourcing requirement attached. If you're specifying a network switch for a project that will receive federal funding, BABA compliance is not optional paperwork.

Traffic cabinets bake in summer heat, freeze in winter, and sit exposed to vibration from passing trucks every day. Commercial-grade network gear was never built for that environment, and when it fails at an intersection or a rail crossing, the cost is not just downtime, it is public safety. This guide breaks down what these networking solutions actually need to deliver for transportation agencies, what to look for when buying, and how Comnet's hardened switches and media converters are built to meet those demands.

Many industrial networks still run copper Ethernet right up to the point where distance, electrical interference, or hazardous voltage potential make copper impractical. A fiber optic media converter solves that problem by bridging copper segments to fiber without redesigning the network around it. For network engineers and integrators specifying equipment for substations, traffic cabinets, or surveillance backbones, picking the right model means understanding fiber types, connector standards, and power requirements before a single port gets wired.

Traffic Signal Controller Networking: Built to Last Every traffic signal controller depends on a network that can match its demands. When a cabinet-mounted controller sends timing adjustments to traffic lights across dozens of intersections, the data has to move cleanly, quickly, and without interruption. The networking hardware inside that cabinet and along the fiber backhaul is what makes or breaks the entire traffic signal control system.

Federal infrastructure funding comes with binding conditions. Under the Build America, Buy America Act (BABA), any organization receiving federal financial assistance for an eligible infrastructure project must use materials produced in the United States.

A Network Engineer's Guide to Protecting Industrial Infrastructure The hardware and software systems controlling power plants, water treatment facilities, and factory floors were never built with cybersecurity in mind. Operational technology OT was engineered for reliability and physical control — not for a threat landscape where industrial networks face nation-state actors and ransomware gangs.

Intelligent transportation systems (ITS) depend on robust, hardened network infrastructure to deliver real-time data that keeps traffic flowing safely and efficiently. Comnet provides the mission-critical connectivity that powers intelligent transportation systems worldwide, enabling departments of transportation, transit agencies, and municipalities to monitor conditions, manage congestion, and respond rapidly to incidents along roadways and highways.

Electric utilities are the backbone of modern society, powering everything from hospitals to data centers. As the bulk electric system (BES) becomes more interconnected, it faces a growing array of cyber threats, including ransomware, supply chain attacks, and targeted intrusions that can disrupt entire regions. Regulatory oversight is intensifying, and the consequences of non-compliance are more severe than ever.

SCADA systems are the operational backbone of critical infrastructure — power plants, oil and gas pipelines, water treatment facilities, and manufacturing floors all depend on them to monitor and control industrial processes. When SCADA network infrastructure fails, the consequences extend far beyond downtime. For network engineers specifying or hardening OT environments, getting the switch architecture right is non-negotiable.
