Based on the part number **W2AC-AZ4B-R2/Q**, this component belongs to the **industrial networking and interface** category, specifically manufactured by **Westermo**. This model is part of the **Wolverine** series, designed for Ethernet extension over legacy copper cabling. --- ### 1. Component Specification Overview The W2AC-AZ4B-R2/Q is an industrial-grade **Ethernet Extender**. It allows high-speed data transmission over long distances using standard twisted-pair copper wires. | Feature | Specification | | :--- | :--- | | **Series** | Wolverine (DDW-120/22x equivalent family) | | **Primary Function** | Ethernet to SHDSL Bridge | | **Transmission Media** | Twisted pair copper (telecom grade) | | **Data Rate** | Up to 15.3 Mbit/s per pair | | **Isolation** | High-grade galvanic isolation (Industrial) | | **Mounting** | DIN-rail mounting | --- ### 2. Key Electronic Features * **SHDSL Technology:** It utilizes Single-pair High-speed Digital Subscriber Line technology, enabling existing phone lines to be reused for modern Ethernet networks. * **Ruggedized Design:** Built with high MTBF (Mean Time Between Failures) components to withstand harsh electromagnetic interference (EMI) and extreme temperatures (-40 to +70°C). * **Diagnostic Port:** Often features a console port (RS-232) for configuration and signal quality monitoring. * **Redundancy:** Supports ring topologies to ensure network uptime if one cable is severed. --- ### 3. Connection Interface The device typically features the following physical ports: 1. **Ethernet Ports:** 10/100Base-TX ports (usually RJ-45) for local LAN connection. 2. **DSL Interface:** Terminal block or RJ-11 for the long-distance copper link. 3. **Power Input:** Redundant DC power inputs (typically 12–48V DC). --- ### 4. Application Context This part is commonly used in: * **Railways:** Signalling systems using old trackside copper cables. * **Utilities:** Power substations where fiber is too expensive to deploy. * **Water Treatment:** Connecting remote pump stations across large distances.
