When upgrading legacy systems to modern IP and PoE devices, running new Ethernet or fiber cables is not always practical. This is where 2-wire Ethernet extenders (also called PoE over 2-wire extenders/converters or 2-wire network/PoE adapters) become essential.
Ourten, a global provider of advanced network transmission solutions, delivers reliable 2-wire IP/PoE products that help system integrators, contractors, and building owners achieve digital transformation without costly rewiring.
In many industries, existing copper wiring still dominates:
● Legacy cabling limitations: Elevators, intercom systems, railway stations, and old buildings often rely on 2-core telephone or signal cables.
● High rewiring costs: Pulling new fiber or Cat6 cabling means construction downtime, higher material costs, and operational disruption.
● Unstable wireless alternatives: Wi-Fi or 4G transmission struggles in high-EMI environments such as elevator shafts, tunnels, or port cranes.
A 2-wire Ethernet extender provides a practical way to reuse existing infrastructure while still supporting modern IP and PoE devices.
Ourten's extenders enable long-distance IP data and PoE power transmission over existing 2-core copper wires, reducing installation costs and simplifying system upgrades.
Key Features:
● Transmission distance: Up to 500 meters with PoE, or up to 1,000 meters for Ethernet-only signals.
● High bandwidth: From full deplux 100Mbps to 1000Mbps depending on model.
● Full PoE support: PoE / PoE+ (up to 30W), powering IP cameras, VoIP phones, intercoms, or multimedia displays.
● Plug-and-play deployment: No need to replace existing 2-core lines.
● Industrial-grade reliability: Special models designed for elevators, railway networks, port operations, and other harsh environments.
1. Security Systems
Use existing 2-core copper wires to connect CCTV cameras, emergency phones, Intercom stations and access control panels.
Make the customers can choose more high quanlity endpoints without high budget on cabling.
2. Railway & Subway Stations
Extend IP cameras and displays over existing copper lines across long station corridors.
Maintain stable, high-quality connections in underground environments.
3. Ports & Cranes
Overcome cabling limits in crane arms and container yards where moving parts make fiber impractical.
4. VoIP Migration
Convert old PSTN analog telephone cabling into IP/PoE connections during telecom upgrades.
Enable smooth migration to VoIP without large-scale cabling projects.
