Wind farms are typically located in remote areas – deserts, mountains, or offshore regions – covering vast territories with numerous turbine towers and harsh environmental conditions. This imposes stringent demands on communication networks in terms of environmental adaptability, long‑haul transmission reliability, and remote operation and maintenance capabilities. MRD™ deeply integrates industrial Ethernet technologies to deliver a full‑link communication solution covering everything from turbine towers, step‑up transformers, collector lines, and substations to the central control center. Certified by authorities such as CEPRI and SGRI, our products are built with industrial‑grade ruggedness validated in extreme environments – helping wind power operators build smart wind farms with minimal on‑site attendance and predictive maintenance.
Industry Background: Unique Challenges in Wind Farm Communications
Extremely harsh environment
The equipment is deployed in fan towers, household boxes or protection-free cabinets. It is subjected to high and low temperature drastic alternation, wind, sand, salt spray, mold, and strong lightning attacks throughout the year, and the life of ordinary commercial equipment is extremely short.Long-distance and chain networking
The wind farm covers several tens of square kilometers and the fan spacing is hundreds of meters. The optical fiber usually adopts a chain or hand-held topology, which requires the equipment to have a strong optical transmission capability and relay function.Strong EMI
Fan inverters and transformers produce strong EMI, which requires equipment to have EMC 4A level and to immunity to disturbances to ensure continuous communication.Difficulty in operation and maintenance, making this expensive
The station is remote, the fault repair time is long, the equipment needs to have power down alarm, optical bypass protection, remote status monitoring, etc. Easy to maintain features.
Terminal Access—Plant Aggregation—Backbone Core tiers to aggregate data to the control center efficiently, securely and reliably.
Supports 24 Ethernet ports including 8×2.5G SFP; any two ports can form a self-healing ring with multiple independent rings; QoS (IEEE 802.1p/1Q and ToS/DiffServ); SNMPv1/v2c/v3

Terminal Access—Plant Aggregation—Backbone Core tiers to aggregate data to the control center efficiently, securely and reliably.
Scenario features:Deployed in the fan tower control cabinet, cabin or box, the space is extremely compact, the vibration is large, and the temperature difference is severe.
Solution Highlights:
Fiber optic transceivers (TOM1000 series):provides 1 Optical 1 Electrical/1 Optical 2 Electrical (Fast Ethernet/Gigabit) model, supports surface mounting and plug-in mounting, used for tower barrel PLC, vibration monitoring, etc. Single point device minimalist optical access.
Entry-level Din-Rail switches (TOM1000/PAT300 series):provides 4/8/16 copper port, can choose PoE power supply (for tower camera power supply), SFPfiber port or full Gigabit model, suitable for converging a small number of terminals.
Universal Din-Rail Switches (TCC4100/PAT300 Series):provides 4 combo ports +12 copper ports, PoE, low-speed serial ports, etc. Variety of combinations, and support for M12/DB9/MD9 rugged connectors to resist vibration.
Key technologies:
Three-proof treatment process:PCB and components are sprayed with three anti-paint to resist salt spray, moisture, and mold erosion, ensuring long-term operation of the in-tower condensation environment.
Optical bypass for power loss (BYPASS):When the device is intentionally powered off, the fiber port automatically forms a physical path to avoid the entire chain network from being paralyzed due to the power failure of a single device, greatly improving the reliability of the link.
Scenario features:Deployed in box transformers, booster stations or wind field centers, a large amount of fan data needs to be aggregated, and the scheduling network is safely isolated at the achieves and level.
Solution Highlights:TNM4000 Series Power Industrial Ethernet Switch.
Key capabilities:
Layer-3 switching and isolation:Enable the Layer-3 routing function, achieves the logical isolation of the fan control network, video surveillance network and management network, and compliant with the "security partition" requirement.
High Density Interface:The maximum can supports 28 GigabitSFP or 22 Fast EthernetST ports, from which dozens of fans can be connected throughout the field.
Modular elastic extension:Supports 8 can plug and unplug service slots, can configure interface modules on demand, and flexibly adapt to wind farm phasing construction.
Power Class A Certification:passes EMC Class 4A test, with after indicator and power-off alarm function, easy to judge on-site and remote status.
Scenario features:Located in the regional centralized control center or dispatching machine room, the backbone data exchange across the wind farm needs to be handled.
Solution Highlights:the TNM6000 series of core switches (see Intelligent Network Distribution Scheme for details) can be selected to provide 4T backplane bandwidth and dual main control/dual powerredundant to ensure that the centralized control center is never interrupted.
