1 Introduction
In 1984, Hirschmann implemented the world's first ever fiber optic based
ETHERNET at the University of Stuttgart, Germany. Then in 1990, Hir
-
schmann introduced the "ETHERNET Ring".
These innovations were followed in 1993 by the first media converters for
fieldbus systems and rapid redundancy in the switched ETHERNET in 1998.
Today, the global specialist for enterprise-wide networks, from fiber INTER-
FACES for fieldbus systems through ETHERNET transceivers, hubs,
switches and routers and fast ETHERNET switches to gigabit ETHERNET
switches, offers a complete system family with unified management.
