Digital-I/O Extender Sets
Irrtum und Änderung vorbehalten
Although the low bandwidth and large voltage swing of
digital I/O signals make them essentially less sensitive to
external noise than for example serial data signals, in some
case the operating conditions necessitate transmission
procedures which are completely resistant to noise effects
along the transmission line.
Glass fibers
used as a transmission medium meet these
requirements ideally while also offering the advantage of
galvanic isolation up to virtually any level between the
connected devices. In installations which are subject to
the risk of severe weather conditions, such as in outdoor
locations or between distant buildings, such a solution
ensures a permanently reliable connection even under adverse
conditions.
Wiesemann & Theis offers a whole family of various glass
fiber interfaces which allow conversion of standard interfaces
into an optical interface for connecting glass fiber cable.
The W&T Digital-I/O Extender Sets, which carry the digital
I/O signals over glass fiber optic cable using a multiplexing
procedure, are described on the following pages along with
the technical data and connection examples.
