The IEX-408E-2VDSL2 is an industrial managed Ethernet extender switch for establishing long-distance Ethernet transmissions over twisted-pair copper wiring. IEX-408E-2VDSL2 units can easily be linked in series to form a long-distance multi-drop configuration, with one IEX-408E-2VDSL2 unit located at each drop-point. Adjacent drop points can be separated theoretically by up to 3 km, with a transmission speed of 1 Mbps achieved using a VDSL2 connection (with a connection distance of 300 m, a transmission speed of 100 Mbps can be theoretically achieved). Each IEX-408E-2VDSL2 unit provides six 10/100BaseT(X) and two DSL ports, giving users an incredible amount of flexibility for linking together a wide variety of devices separated by vast distances.

Ethernet redundancy is provided by Turbo Ring, Turbo Chain, RSTP/STP, and MSTP, and a controllable bypass solution on the DSL ports that increases system reliability and the availability of your network. The IEX-408E-2VDSL2 Series also supports advanced management and security features. It is the perfect solution for reducing the cost of deploying new network cable installations using existing twisted-pair copper wiring to extend copper cable networks beyond the conventional distance limitations imposed by the Ethernet protocol.

The wide operating temperature range (-40 to 75°C), and dual power inputs make it ideal for deployment in industrial applications such as ITS, rail wayside, oil and gas, mining, factory automation, and process automation applications. In addition, its compact design that includes a DIN-rail, makes it ideal for installation in places with space limitations such as a cabinet.

To simplify configuration, the IEX-408E-2VDSL2 uses CO/CPE automatic negotiation (the factory default setting). The device will automatically assign CPE status to one of each pair of IEX devices. In addition, advanced management and monitoring functionalities can be performed through a NMS, including a virtual panel, which can improve the user experience by enabling quick troubleshooting.
