MManaged and unmanaged Ethernet Extenders over copper– running on SHDSL technology - from industry leader Westermo

Ethernet Extenders

Extend your network far beyond the normal limits of Ethernet

The Westermo Wolverine series of industrial Ethernet extenders allow cost-effective Ethernet networks to be created over long distances, at high data rates. The SHDSL technology employed makes it possible to reuse many types of pre-existing cabling which in turn can lead to considerable financial savings. With support for multidrop networks, redundant rings, legacy serial connections and layer 3 routing functions, our range of Ethernet extenders can meet any demand your application requires.

The Westermo Wolverine DDW-142-12VDC-BP Industrial Ethernet Line extender is based on SHDSL technology and enables existing copper cables to be used to create Ethernet IP-based networks. This helps to achieve significant time and cost savings when installing new communication networks.

Because old cable networks were rarely installed with resilient data paths in mind, there is a potential risk when using these as part of a modern IP-based network. Should a unit suffer a power failure, the Wolverine Line Extender’s integrated bypass relay short-circuits the two SHDSL interfaces allowing a renegotiation between adjacent extenders; this allows communication to be restored automatically.

In addition, the Westermo Wolverine series offer `power failure resiliency’ ensuring continued network operation in the event of a primary power failure. A dual power supply is now complimented by a 12 VDC option, which enables a batt ery to provide the power supply redundancy. The transition between primary and secondary power is immediate and seamless, ensuring maximum network uptime.

The DDW-142-12VDC-BP enables networks to be created over distances of up to 15km, offering data rates of over 15 Mbits/s on a single twisted pair cable. Bonded pairs double this rate to over 30 Mbit/s. An integral switch enables two Ethernet devices to be attached and a further RS232 port ensures legacy equipment can be incorporated into an IP network.

The DDW-142-12VDC-BP is very easy to install, with no configuration required for basic applications and a web interface to support simple configuration for more complex networks. The device is ideal for basic point-to-point or multidrop networks in applications where failures can result in significant costs. The WeOS operating system supports secure and resilient multi media ring networks.

The unit offers exceptional reliability and is certified for installation in environments with high levels of vibration and extreme temperatures such as those found in rail, marine and the utility applications.

DDW-142 Industrial Ethernet Extender

1. Save time and money reusing old cable and equipment
2. From 32 kbit/s to 15.3 Mbit/s Ethernet over twisted pair or up to 30.4 Mbit/s with bonding
3. 2 port 100 Mbit L2 switch supporting VLAN and QoS
4. Legacy connection via RS-232 port
5. Ring topologies available for Ethernet and/or serial networks

The two SHDSL ports can be bonded together giving a duplicated bandwidth on a 4 wire connection.

Unmanaged plug and play extenders for industrial Ethernet

The Westermo Wolverine range of point to point industrial Ethernet extenders allow a network to be linked beyond the standard 100m limit. Utilising SHDSL technology on twisted pair cables, the point to point Wolverine Ethernet extenders provide high data rate connections over long distances. With a robust design, the Wolverine extenders are designed for use in harsh environments and, with our many years of experience in railway applications, meet the many specific needs of the rail industry.

The Wolverine series of Ethernet extenders allow cost effective Ethernet networks to be created over long distances, at data rates of up to 15.3 Mbit/s. The SHDSL technology makes it possible to reuse many types of pre-existing copper cables. This can lead to considerable financial savings as expensive fibre cables do not need to be installed. Dependent on cable characteristics, distances up to 15 km (9.3 mi) can be achieved. Configuration of the DDW-120 is performed using only DIP switches, which ensures rapid installation.

Extend your managed network with the Wolverine

The Westermo Wolverine range of managed industrial Ethernet extenders allow a network to be linked beyond the standard 100m limit, whilst providing support for SNMP v3. Utilising SHDSL technology on twisted pair cables, the managed Wolverine Ethernet extenders provide high data rate connections multidropped over long distances. Our managed range of Ethernet extenders has approvals for use in industrial and railway applications, as well as explosive environments.
