Dupline
/Optical Fibre Converters
Types G 3492 0000 and G 3493 0000
Converts Dupline
for transmission on optical fibre
Runs on optical multimode fibre pairs
(50/125, 62.5/125)
ST type connector
Up to 5 km optical transmission distance with
62.5/125 fibre
DIN-rail mounting
LED-indications for supply and fibre connection
AC power supply
The G34930000 converts the
Dupline
signal for transmis-
sion on optical multimode
fibre pairs (50/125, 62.5/125).
The G34930000 always oper-
ates together with a
G34920000, which converts
the signal back from optical to
electrical representation via a
built-in channel generator
output stage. Up to 5 km
optical transmission distance
can be achieved.

G 3492 0000, G 3493 0000
Mode of Operation
The Dupline
Optical Con-
verters enable the use of
glass fibre as transmission
media on one or more sec-
tions of a Dupline
Fieldbus
network. The possibility to
freely combine electrical and
optical media makes it easier
to adapt the Dupline
Field-
bus to the system require-
ments. Optical Fibres can be
useful when Dupline
signals
have to be transmitted out-
door in geograhpical areas
with frequent thunderstorms,
or in case of sections with
heavy noise induction.
The G 3493 0000 converts
the Dupline
signal from elec-
trical to optical level, while the
G 3492 0000 with built-in
channel generator converts
the carrier signal back from
optical to electrical level (se-
condary Dupline
). Up to 5
km distance can be achieved
on the glass fibre, which can
have the dimensions 50/125
or 62.5/125. Two optical fibres
are required for connecing the
two Optical Converter Units.
