Network Extender SPE

Ethernet Extension with the Network Extender SPE from Wiesemann & Theis

The Network Extender SPE from Wiesemann & Theis is a compact and efficient solution for connecting Ethernet devices over long distances using a simple 2-wire cable or Single Pair Ethernet (SPE). Designed for applications in Industry 4.0, building automation, and traffic technology, the SPE converter enables reliable data transmission over distances of up to 1000 meters without additional configuration. Thanks to its plug & play operation, support for Power-over-Ethernet (PoE), and robust design for DIN rail mounting, the Network Extender SPE is ideal for environments where flexibility, range, and reliability are crucial. This article highlights the technical features, applications, and benefits of this innovative solution for Ethernet range extension.

Ethernet Connection over Long Distances

The Network Extender SPE enables the connection of any Ethernet devices via Single Pair Ethernet (10BaseT1L Full Duplex) or other 2-wire cables such as bell wire, with ranges up to 1000 meters when using SPE cables. In lab environments, transmissions of over 600 meters have been achieved with standard bell wire, though range depends on cable quality. The converter operates without its own intelligence, ensuring true plug & play operation. With an Ethernet interface (10BaseT Full Duplex) and an SPE interface, both supporting auto-negotiation and auto-MDIX, integration into existing networks is straightforward. This capability to realize Ethernet connections over long distances with minimal cabling effort makes the Network Extender SPE an ideal solution for applications where conventional Ethernet cables reach their limits.

Plug & Play for Easy Integration

Commissioning the Network Extender SPE is extremely simple thanks to its plug & play operation. Since the converter operates without its own intelligence, no complex configurations are required. Devices are connected via the Ethernet or SPE interface, and data transmission begins immediately. For extended diagnostics or information purposes, an optional WLAN module can be activated providing access to status and debugging information. This ease of use makes the Network Extender SPE especially attractive for users needing a fast and low-maintenance solution for Ethernet extension, for example in building automation or traffic technology.

Flexible Power Supply for Versatile Use

The power supply of the Network Extender SPE is highly flexible and supports both Power-over-Ethernet (PoE) (Class 1) and external supply via a pluggable screw terminal (24V-48V DC). PoE enables powering over Ethernet data pairs (phantom power) or unused wire pairs, facilitating installation in environments without separate power sources. The galvanically isolated power connection provides additional safety and protection against electrical interference. This flexibility makes the Network Extender SPE ideal for use in various scenarios, from industrial production halls to distributed traffic control systems.

Robust Interfaces for Industrial Applications

The Network Extender SPE features two interfaces: an Ethernet interface (10BaseT Full Duplex) and a Single Pair Ethernet interface (10BaseT1L Full Duplex), both supporting auto-negotiation and auto-MDIX. These interfaces allow seamless integration into existing networks and the connection of devices over long distances with minimal cabling effort. The robust construction of the device, including the option for DIN rail mounting, makes it ideal for use in demanding environments such as production facilities, building cabling, or traffic control systems. Support for Single Pair Ethernet also enables the use of cost-effective 2-wire cables, which lowers installation costs and increases flexibility.

Comparison with Other Ethernet Extension Solutions

Compared to conventional Ethernet extenders or fiber optic solutions, the Network Extender SPE offers a cost-effective and space-saving alternative. While fiber optic solutions often require expensive converters and special cables, the SPE converter uses simple 2-wire cables or SPE cables that are often already available in many environments, such as bell wire in buildings or twisted-pair cables in industry. Unlike other Ethernet extenders that often require complex configurations, the Network Extender SPE relies on plug & play operation without its own intelligence, simplifying setup and maintenance. For applications requiring additional security functions such as firewalls or network monitoring, other Wiesemann & Theis products like the Fix Defined Firewall or IP-Watcher provide suitable complements.

Versatile Applications

The Network Extender SPE is designed for a wide variety of applications in Industry 4.0, building automation, and traffic technology. In industry, it enables the connection of sensors, controllers, or IoT devices over long distances, e.g., in extensive production halls. In building automation, it connects devices such as climate or lighting controls that can be connected via existing 2-wire cabling. In traffic technology, the Network Extender SPE is suitable for networking control systems in tunnels, train stations, or traffic management systems where long ranges and robust connections are needed. Other applications include integration of IoT devices, networking legacy systems, and extending networks in remote areas.

Standards Compliance and Reliability

The Network Extender SPE is standards-compliant and designed for use in office and industrial environments. It offers high immunity to interference according to EN 61000-6-2 and low emission of disturbances according to EN 55032:2015 + A1 Class B, EN 61000-3-2, and EN 61000-3-3. These features ensure reliable and interference-free operation even in electromagnetically demanding environments. The robust design and DIN rail mounting option make the device ideal for industrial applications. With a five-year warranty, the Network Extender SPE provides a durable and reliable solution for Ethernet extension.
