New sealed WESTERMO DDW-120 ETHERNET EXTENDER 3621-0110

The Westermo DDW-120 is an unmanaged Ethernet SHDSL extender in the Wolverine series, designed to carry 10/100 Ethernet over existing two-wire copper at data rates up to 15.3 Mbit/s and, depending on cable characteristics, across distances up to 15 km (9.3 mi). That lets industrial plants, rail trackside installations and traffic-control sites extend a network over cabling they already own instead of laying new fibre. Configuration is handled entirely by DIP switches — no software required — and the unit passes VLAN, multicast and IPsec traffic transparently, working with industrial protocols such as Modbus/TCP and Profinet IO.

This listing is for one new DDW-120, Westermo article number 3621-0110. Note for accuracy: the eBay title describes the unit as factory sealed, while the listing's condition field records it as new, open box — go by the photographs, or ask us and we'll confirm how the unit presents before you order.
