IoT Gateways
Ethernet & Optical Solutions for IoT Gateway Connectivity
IoT gateways are the critical bridge between edge devices and the cloud, aggregating data and securely forwarding it via wired and wireless networks. LINK‑PP provides high-performance RJ45 magnetic jacks, PoE-capable LAN transformers, and SFP interface support for fiber uplinks. These interfaces ensure reliable, EMI-protected connectivity for smart city nodes, industrial sensors, and remote environmental monitors.
Connectivity Challenges in IoT Gateway Applications
- Multi-protocol Support — Gateways must integrate Ethernet, fiber, and wireless for redundancy
- EMC & Surge Immunity — Outdoor and industrial deployments require strict EMI control
- Power Efficiency — Gateways may be solar- or PoE-powered, requiring low-loss magnetics
- Environmental Durability — Extended temp and humidity resistance for field deployment
