7.2.15 Optical FireWire connection
Greater distances in FireWire networks can be bridged
with optohubs that enable distances of up to 300 m with
the use of a fiber optical cable.
This mode is used primarily for widely distributed mod
ules, e.g. in the rail vehicle application environment, gen
eral monitoring of traffic or energy infrastructures, as well
as in marine applications.
Another advantage in addition to wide measurement
module distribution and the associated short sensor
leads, is fullyisolated data communication between dif
ferent system components, to suppress the electromag
netic interference of high overhead line voltages in rail
traffic, for example.
