Every outdoor network deployment starts with the same short list of problems: how do you power the device, how do you protect it from the environment, and how do you connect it back to the network. Historically, that meant sourcing an enclosure, a power supply, circuit breakers, surge protection, and cable management separately, then building the whole thing in-house before it ever reached the field.
Comnet has added three new Ethernet switches to its portfolio: the CNG7F2T5P, CWX4F20T4M, and CNX16F4T12MPB. Each one addresses a scenario that comes up repeatedly in security, industrial, and government network design: unmanaged edge deployments, high-power PoE for demanding field devices, and high-density managed cores. All three are TAA and NDAA compliant.
A camera feed drops at 2 a.m. in a substation control room. A traffic signal loses its uplink during a heat wave. A factory floor network goes dark after two years of vibration and electrical noise. Commercial-grade switches aren't built for these conditions, and when they fail, the cost shows up as downtime, safety risk, and emergency truck rolls. Hardened Ethernet switches exist to solve exactly this problem.
Network bottlenecks cost infrastructure operators time, money, and reliability. When an access point, IP camera, or industrial sensor connects to an aging Fast Ethernet switch, data transmission crawls at 100 Mbps while modern devices demand 1 Gbps and beyond. For security integrators, utilities, and transportation departments, the choice between Fast Ethernet and gigabit ethernet switches determines whether your network keeps pace with bandwidth-intensive applications or becomes the weak link in your infrastructure.

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.
