Built specifically for high-speed outdoor deployments, this compact device protects Ethernet-connected hardware such as access points, cameras, bridges, and base stations operating in exposed environments. The protector features two passive surge-protected RJ45 connections that act as a secure inline barrier between outdoor devices and the rest of the network infrastructure. By diverting harmful transient voltages away from connected equipment, it helps prevent failures caused by lightning-induced surges, static buildup, or unexpected electrical spikes. This makes it especially valuable for installations on rooftops, poles, towers, and building exteriors where environmental exposure increases electrical risk.The ETH-SP-G2 supports modern high-speed data transmission with protection for Ethernet lines operating at up to 2.5 Gbps. It also maintains compatibility with Power over Ethernet, ensuring that both data and power delivery remain uninterrupted while still benefiting from surge suppression. The durable polycarbonate enclosure and IPX5-rated weatherproof design enable reliable operation in demanding outdoor conditions. Despite its robust protection capabilities, the unit remains lightweight and compact, making installation straightforward without adding bulk to the deployment. Designed for quick and easy installation, the surge protector integrates seamlessly into existing Ethernet runs without requiring complex configuration. This makes it an essential component for protecting outdoor network investments and ensuring consistent performance in environments where electrical interference and atmospheric conditions can otherwise compromise connectivity.Electrical StabilityBeyond its physical durability, the ETH-SP-G2 provides advanced electrical protection engineered for stable operation in high-speed networking environments. The device utilizes a controlled DC spark-over voltage of 90V at 100V/s and supports a maximum impulse spark-over voltage of 700V at 1kV/µs. This controlled response enables it to safely absorb and redirect sudden voltage spikes before they reach connected equipment. With a discharge current capability exceeding 10kA, the protector is designed to handle substantial transient loads typically caused by lightning events or electrostatic discharge. Its insulation resistance reaches up to 1 G ohm at 50V, minimizing leakage and ensuring stable signal integrity even under stress conditions.The unit also maintains a maximum capacitance of just 1.0 pF at 1 MHz, which helps preserve signal quality across high-speed connections without introducing measurable interference. Integrated ESD protection reacts dynamically to transient voltage surges ranging from 100V/s to 1kV/µs, absorbing excess current and preventing damage to connected devices. The protector operates reliably across a wide ambient temperature range from -30 to +65 °C, making it suitable for installations in harsh climates. In addition, it meets ETSI300-019-1.4 shock and vibration standards, ensuring dependable performance in environments subject to mechanical stress such as towers, industrial sites, and transport-related infrastructure. Together, these electrical protection characteristics allow the ETH-SP-G2 to support stable network performance while significantly reducing the risk of equipment failure due to environmental electrical disturbances.
