estermo has enhanced its series of Ethernet line extenders with
the release of a high-speed, compact device that is capable of
meeting the increasing data transfer demands within industrial ap-
plications.The DDW-142 is the latest addition to theWolverine range,
which uses SHDSL technology to establish a high-speed connection
between Ethernet networks using any existing copper cables. This
can enable considerable cost savings when installing new systems
where in the past the only option would have been fibre.
The DDW-142 is a fully managed device with Layer 2 switch func-
tionality that enables effective Ethernet networks to be created over
distances of up to 15 km. Data rates of up to 30,4 Mbits/s are possible,
making the device suitable for connecting complex networks that
may include a large number of devices requiring high bandwidth.
An integral 2-port 100 Mbit switch allows two Ethernet devices to
be attached and a RS-232 port enables legacy devices to be easily
incorporated into the IP network.
To support engineers that are installing and maintaining ever
increasingly complex networks, the DDW-142 has been designed to
be extremely easy to set up, requiring no configuration for simple
point-to-point communications. For larger networks, a web interface is
provided and a CLI allows even more complex configuration.TheWol-
verine range is also supplied with a unique cable distance calculator.
The DDW-142 is designed for use in tough environments and mis-
sion critical railway, road or utility applications where device failure
could result in significant costs. The rugged and very compact unit
can operate in extreme temperatures (-40 to +70°C) and where EMC
and vibration levels are high. Total galvanic isolation and transient
protection of the electronics contribute to a Mean Time Between
Failure of 437 000 hours, ensuring high operational reliability and
a long service life.
