Lantech industrial Ethernet switches connect roadside equipment to the wider traffic management network. For U.S. intelligent transportation systems (ITS), the right switch needs to match the cabinet environment, camera power requirements, fiber backbone and network security policy.
Tekdis LLC supplies Lantech industrial switches for OEMs, system integrators and infrastructure projects in the United States. From a compact roadside cabinet to a traffic management center (TMC), switch selection starts with the equipment you need to connect and the service you need to maintain.
This guide covers managed industrial Ethernet switches, industrial PoE switches, Gigabit Ethernet, SFP fiber uplinks and the security features to consider when planning a traffic network upgrade.
Why use managed industrial switches for ITS?
A modern intersection can bring together signal controllers, surveillance cameras, vehicle detection sensors and dynamic message signs. Connecting these devices increases visibility across the road network, but also increases the number of access points that need to be managed.
An unmanaged Ethernet switch can suit a simple connection where configuration and monitoring are unnecessary. A managed industrial switch is the more suitable starting point when the project requires traffic separation, access controls, link redundancy or remote fault diagnosis.
Lantech's ITS portfolio brings together PoE, network management and redundancy functions for transport applications. Specify features against the selected hardware and software package. [1]
Start with your network layout: identify each field device, its bandwidth and power demand, its permitted communications and the route back to the TMC. This makes it easier to select the required port count and uplink capacity.
Industrial Ethernet security at the roadside cabinet
Roadside cabinets are distributed across public spaces. A network design should account for physical access to ports, unauthorized devices and the consequences of an incident spreading between connected systems.
Control access and separate traffic
Use a managed switch configuration that limits access to approved devices and separates controller, camera and sensor traffic. VLANs provide logical separation; enforce communication rules with appropriate access controls, routing and firewalls.
Lantech OS5 supports functions including 802.1X authentication, port security, VLANs and access control features. Optional IEC 62443-4-2 SL2 cybersecurity and MACsec features are available within the platform. [2]
Specify the security option you need
For an IEC 62443 industrial switch requirement, request the certificate scope, applicable hardware, firmware and ordering option. Component certification is one part of a wider security design and does not establish compliance for an entire traffic network.
Where Ethernet link encryption is required, confirm MACsec support at both ends of the link. Include key management, endpoint compatibility and monitoring in the design, alongside physical cabinet security and secure remote access.
Upgrading existing intersections? A managed switch can add network controls around existing Ethernet-connected controllers. Review each controller's interfaces and operating requirements before planning the change.
Industrial PoE switches and fiber uplinks
An industrial Power over Ethernet (PoE) switch carries data and power to compatible IP cameras and other powered devices over the same cable. For traffic surveillance, check both the power available at each port and the total switch PoE budget.
Include the camera's maximum load, any heater or infrared lighting, the cabinet's DC supply and the cable installation. If a device needs PoE++, specify the required power and IEEE 802.3bt support explicitly.
Fiber Ethernet uplinks connect roadside cabinets over longer distances. Match SFP or SFP+ transceivers to the required speed, fiber type, wavelength, connector and link distance. Gigabit Ethernet access ports and higher-bandwidth uplinks should be sized around the expected camera and sensor traffic.
Redundant networks for demanding field conditions
A broken uplink can interrupt the connection between roadside equipment and the traffic management center. A redundant Ethernet ring provides an alternate path when a link fails, provided the topology and protection configuration support it.
Lantech OS5 supports ITU-T G.8032 Ethernet Ring Protection Switching (ERPS). Validate recovery behavior across the complete network, including third-party switches and connected applications, against the project's outage tolerance. [2]
Environmental suitability matters just as much. Select a rugged industrial Ethernet switch for the measured cabinet temperature, available DC input, electrical conditions and mounting space. Check DIN rail or rack mounting requirements, redundant power inputs and any specified isolation or surge protection.
Plan remote maintenance from the start. Useful information includes link state, power status, device temperature and event history. Agree how alarms reach the operations team and how replacement switches receive an approved configuration.

Choosing Lantech industrial switches for your project
Use the following checklist to prepare a quotation request for a new ITS installation or an upgrade to an existing traffic signal network.
| Requirement | What to specify |
|---|---|
| Connected devices | Controller, camera and sensor quantities; copper port speeds; spare ports for expansion. |
| PoE power | IEEE 802.3af, 802.3at or 802.3bt; maximum watts per device; total power budget. |
| Fiber backbone | SFP or SFP+ uplinks, link speed, single-mode or multimode fiber, and distance. |
| Network management | VLAN plan, QoS requirements, multicast traffic and any Layer 3 routing needs. |
| Cybersecurity | Access policy, authentication, encrypted management and required certification scope. |
| Availability | Ring topology, recovery target, redundant DC inputs and replacement procedure. |
| Cabinet conditions | Temperature range, dimensions, mounting method, input voltage and electrical protection. |
Send Tekdis LLC your topology, equipment list, quantities and delivery targets. Include any agency specification so the proposed switch can be checked against the actual project requirements.

Lantech industrial switch FAQs
What are Lantech industrial switches used for?
Lantech industrial switches connect Ethernet devices in applications such as traffic management, surveillance, industrial automation and transportation. The required model depends on port count, power, environment and network management needs.
Do traffic networks need a managed or unmanaged switch?
Choose a managed switch when the network needs VLANs, access controls, redundancy or remote monitoring. An unmanaged switch can suit simple connections where those functions are unnecessary.
Can an industrial PoE switch power traffic cameras?
Yes, when the camera and switch support compatible PoE standards. Check maximum power per port, total PoE budget, DC supply capacity and the camera's peak power demand.
Do all Lantech switches include MACsec and IEC 62443 certification?
No. Security features and certification depend on the product, firmware and selected options. Specify the required MACsec capability and IEC 62443 certificate scope when requesting a quotation.
