Role: Network edge, direct connection to end devices.
Core Devices: PoE Switch, Industrial PoE Switch.
Key Functions: Transmits video data and supplies power to IP Cameras via Ethernet cables, eliminating power line wiring issues.
Special Scenario: Industrial PoE Switch is deployed in harsh environments (outdoor, extreme temperature, strong electromagnetic interference).
Role: Aggregates data from multiple access-layer switches for upstream transmission.
Core Device: Managed Switch.
Connection Mode: Fiber optic links (orange dashed lines, transceiver modules) between access-aggregation and aggregation-core layers.
Advantages: Surpasses 100m Ethernet cable limit for long-distance transmission; high bandwidth prevents video data congestion.
Role: Network “brain” and terminal.
Core Device: Core Switch (high data throughput for smooth video transmission).
Backend Devices:
Monitoring Station: Real-time video viewing.
NVR/VMS Server: Data storage and playback.


In the vast production areas of modern automated factories, production equipment is scattered across assembly lines, CNC machining areas, and high-bay warehouses. Building a network solution (such as monitoring and office networks) between these devices faces several challenges: electromagnetic interference from heavy-duty motors, continuous mechanical vibration, and high/low temperatures (temperatures in some non-air-conditioned workshops often exceed 55°C).
This solution will utilize Wanglink industrial-grade switches and fiber optic media converters to build a robust and durable “industrial-grade capillary network,” completely covering every corner of the factory and providing stable network connectivity to even the most remote terminal devices.
1、Edge Access Layer:
Products Used: Wanglink DIN rail-mounted industrial unmanaged switches and fiber optic media converters
Application Scenarios:
Interconnection of Robotic Arms and Programmable Logic Controllers (PLCs)
Wanglink industrial unmanaged switches are directly installed on DIN rails in ultra-thin wall-mounted control cabinets, serving as the core connection hub for programmable logic controllers (PLCs), human-machine interface (HMI) panels, and robotic arm controllers.
Advantages:
Wanglink Industrial switch features a DIN rail mounting design and can be easily and securely installed in control cabinets, with no worry about mechanical vibrations from surrounding equipment; and the dual power input redundancy design provides double protection for stable connectivity, ensuring that the network remains operational even if one power supply fails, avoiding production downtime losses caused by single-point power failures.
2、Aggregation Control Layer:
Data generated by each production unit – whether from robotic arm workstations, CNC machine tools, or quality inspection cameras – needs to be aggregated and securely transmitted in real-time, seamlessly, and without delay to the factory’s data acquisition and monitoring system (SCADA).
Products Used: Wanglink Industrial Managed Switches with SFP Fiber Ports
Application Scenarios:
High-Reliability Fiber Optic Ring Network Construction
Using the SFP fiber ports of Wanglink industrial managed switches (with ring network functionality), switches in different workshops are interconnected to build a redundant ring network topology.
Advantage: If a fiber optic cable is accidentally damaged – for example, by a forklift during material handling or construction – the built-in Ethernet Ring Protection Switching (ERPS) protocol can automatically switch the data transmission path within 20 milliseconds, almost imperceptibly. This ensures zero data loss, and the assembly line can continue to operate without interruption.

In the current phase of comprehensive broadband infrastructure upgrades and accelerated smart city construction initiatives, ISPs and network operators are confronted with a fundamental challenge: how to architect a foundational network infrastructure capable of adapting to complex outdoor environments, maintaining compatibility with existing legacy systems, and simultaneously guaranteeing business continuity with zero service interruption.
This solution leverages the combined deployment of industrial-grade PoE switches, fiber media converters, and optical transceiver modules to deliver a network architecture that balances resilience with cost efficiency.
Product: Industrial-grade PoE Switch (Protection Class IP40, Operating Temperature: -40℃ to 75℃)
Core Scenarios:
Core Value: PoE++ technology provides up to 90W of power per port, eliminating the cost of separate wiring; wide temperature range and IP40 protection adapt to extreme climates without the need for expensive temperature-controlled cabinets, reducing outdoor installation costs by over 50% and significantly minimizing environment-induced equipment failures and maintenance work orders.
Product: Fiber Media Converter (Ethernet Electrical-to-Optical Signal Conversion Device)
Core Scenarios:
Core Value: No hardware replacement required, protecting prior investments; single-mode fiber extends transmission distance from 100-meter level to over 20 kilometers, eliminating the need for relay equipment and enabling full-bandwidth, low-latency transmission.
Product: Layer 3 Managed Aggregation Switch + SFP+/QSFP Optical Modules
Core Scenarios:
Core Value: ERPS protocol enables 20 ms faulty link switching, imperceptible to users, improving SLA achievement rate and reducing fault complaint work orders by over 90%; VLAN isolation and QoS priority prevent congestion and guarantee bandwidth for critical services.
Core Product: Hot-Swappable Optical Modules (SFP/SFP+/QSFP28 Series)
Core Scenarios:
Core Value: A single switch chassis supports multi-generation module upgrades, with a service life of over 10 years, reducing total lifecycle capital expenditure by over 60%; standardized equipment and customized modules simplify inventory and operation & maintenance.

A: An industrial ethernet switch is a ruggedized network device designed for harsh environments. Unlike commercial switches, it withstands extreme temperatures, vibrations, and electromagnetic interference, making it the best industrial ethernet switch choice for factories and outdoor use.
A: The main differences lie in durability and components. Industrial grade ethernet switches use high-quality chips, fanless cooling designs, and redundant power inputs (often DIN-rail mountable) to ensure zero downtime in critical operations.
A: Choose an industrial ethernet switch din rail model for compact control cabinets or limited spaces. Choose industrial rackmount ethernet switches (usually 19-inch) for server rooms or central control centers requiring high port density (24 to 48 ports).
A: WangLink is a certified industrial ethernet switch manufacturer based in China. We have our own R&D team and production lines, allowing us to offer competitive pricing and custom OEM/ODM services to global industrial ethernet switch vendors.
