The ETH-SP-G2 from Ubiquiti Networks is an ESD protection device for high-speed networks in outdoor environments. It protects outdoor Ethernet devices from transient voltage surges caused by electrostatic discharges (ESD) or electromagnetic pulses (EMP). The device features two passive, surge-protected RJ45 ports and is designed for use in GbE networks. The quick and easy installation enables uncomplicated integration into existing outdoor network infrastructures.

Applications

The ETH-SP-G2 is specifically designed for use in outdoor installations, where Ethernet devices are exposed to increased risks from electrostatic discharges and atmospheric overvoltages. Typical applications include industrial networks, outdoor security cameras, WLAN access points, or other network devices installed outdoors. The weather resistance according to IPX5 ensures protection against splashing water, securing its usability in various climatic conditions.

Features and Specifications in Detail

The device offers two RJ45 sockets serving as input and output for Ethernet connections. The protection function is based on absorbing transient currents, with a response to voltage surges ranging from 100 V/s to 1 kV/µs. The DC spark-over voltage is 90 V at a rate of 100 V/s, while the maximum impulse breakdown voltage is 700 V at 1 kV/µs. The discharge current is 10kA and more, indicating a high absorption capacity for short, intense voltage surges. The maximum insulation resistance is 1 Gigaohm at 50 V, ensuring high electrical insulation and thus secure separation of the lines. The maximum capacitance of 1.0 pF at 1 MHz ensures that data transmission is not impaired by the protection mechanism.

Technology Explained Simply

The protection mechanism of the ETH-SP-G2 works by absorbing transient voltage surges caused by ESD or EMP. These surges can damage network devices, especially when installed outdoors. The device reacts quickly to such events and safely diverts the energy without interrupting data transmission. PoE support enables the use of the device in networks employing Power over Ethernet, without affecting power delivery through the network cable. The operating temperature range of -30 to 65 °C and operating humidity of 10 to 90 % non-condensing make the device suitable for a wide range of environments, including industrial or harsh outdoor conditions.

Compatibility and Accessories

The device is compatible with 10/100/1000 Ethernet networks and supports PoE, making it suitable for a wide range of network devices. The interface connections consist of two RJ45 sockets that can be directly integrated into existing network cables. Shock and vibration certification according to the ETSI300-019-1.4 standard ensures high mechanical stability, which is important for use in moving or vibrating environments.

Mounting and Installation

Installation is performed by directly connecting the RJ45 ports into the existing network infrastructure. No additional tools or special mounting procedures are required. The passive design requires no external power supply, simplifying installation and enhancing operational reliability.

Operational Advantages

The ETH-SP-G2 provides reliable protection for outdoor Ethernet devices against transient voltage surges without impairing network performance. PoE support and high mechanical stability make the device a robust solution for outdoor use. The IPX5 weather resistance and wide operating temperature range increase operational safety in various environments. The simple installation and passive operation reduce maintenance requirements and enhance the overall network reliability.
