Smart Meters
Ethernet & Optical Connectivity for Smart Meter Applications
Smart meters play a vital role in modern utility infrastructures, enabling real-time data collection, remote control, and networked billing. LINK‑PP supports the development of Ethernet-based and fiber-enabled smart metering systems with a complete range of RJ45 magnetic connectors, LAN magnetics, and SFP-compatible optical interfaces. These components are tailored for industrial-grade reliability, EMI suppression, and compact integration into low-power embedded systems.
Networking Requirements in Smart Meter Systems
- Low Power Operation — Devices must consume minimal power while maintaining reliable data communication.
- EMC Compliance — Utility environments demand Class B EMC performance to avoid interference.
- Rugged Design — Components must withstand temperature, humidity, and surge events.
- Hybrid Connectivity — Many meters use both Ethernet and GPON uplink to utility data concentrators.
