Version 1.0 11/97
1 Introduction
The fiber-optic FIP repeater OZD FIP G3 is designed
for use in optical FIP field bus networks. It permits
conversions of electrical FIP interfaces into optical
FIP interfaces and vice versa.
The repeaters can be integrated into existing FIP field
bus networks. OZD FIP G3 repeaters can also be used
to configure a complete FIP field bus network with
line or ring topology.
The mechanical structure comprises a compact, rigid
metal housing which can either be mounted on a top-
hat rail or on any flat base.
No adjustment is necessary during start-up.
Ports
The repeater has three mutually independent
channels (ports), each of which in turn consists of
a transmitter and a receiver.
Port 1 is a 9-pin Sub-D connector (male). Ports 2 and 3
are optical BFOC/2.5 (ST ®) sockets.
Power supply
The operating voltage is +24 V to +48 V DC.
A redundant power supply from two separate sources
is provided to increase operational reliability. The two
operating voltages can be supplied to two different
terminals of the 5-pole terminal block.
Both connections are decoupled via diodes in order
to prevent feedback or destruction resulting from
polarity reversal.
There is no load distribution between the sources.
With redundant supply, only the power supply unit
with the higher output voltage provides the bus
adapter with power.
Signaling contact
Various repeater malfunctions can be indicated via a
signaling contact (relay with floating contacts). The
connections of the signaling contact also terminate at
the 5-pole terminal block.
LEDs
Four two-color LEDs indicate the current operating
status and any malfunctions.

1 Introduction

Fiber-optic technology
The implementation of fiber-optic technology permits
very long transmission ranges and provides optimum
protection against EMI effects both along the trans-
mission link and (owing to the electrical isolation) at
the repeaters themselves.
Transmission rate
The fiber-optic FIP repeater OZD FIP G3 functions
at a transmission rate of 1 MBit/s (as defined in
EN 50 170).
Signal regeneration
The fiber-optic FIP repeater OZD FIP G3 regenerates
the signal shape and amplitude of the received data.
This function permits a maximum of 20 repeaters to
be cascaded via optical links.
FIP protocol
In a network topology as shown in Fig. 2, 3 and 4 (Ch. 2),
a response time must be taken into consideration at
the arbiter and in the data terminal equipment. The
data which is sent out, is returned to each optical port
by the neighboring device. This status signal is used
to monitor the output and the rings.
The response time is composed of the transfer time in
the optical fiber (5 ns/m) and the transfer time through
a repeater (< 1µs).
At a maximum transmission distance of 2.5 km, the
response time is as follows:
tresponse = 2 x 2500 m x 2 ns/m + 1 µs = 26 µs
If there is a break along the optical fiber, a predefined
waiting time of 30 µs is activated in the repeaters
affected by the fault (system LED red). This must be
taken into account when the system is planned.
Redundancy
Redundant signal transmission ensures a very high
degree of transmission reliability.
Redundant operating voltage supply can increase
operational reliability even further.

This network topology is used in the case of an optical
link between data terminal units or bus segments.
The implementation of a redundant link with OZD FIP
G3 repeaters ensures a high degree of reliability.
A maximum of 20 repeaters can be operated in one
optical ring.
The failure of an optical cable between any two
OZD FIP G3 repeaters does not affect the availability
of the network.
The repeaters detect total failure of an optical link. The
port LED of the faulty link is deactivated and the failure
is indicated by illumination of the red system LED and
response of the signaling contact.
It is advisable to install the duplex optical cables of
the two optical channels along different routes.

If problems are encountered with the configuration
of a redundant optical ring on account of excessively
long fiber-optic line sections, connections can also be
implemented as shown in Fig. 2.
In this case, each repeater is linked (in spatial terms)
with the next repeater but one. Two adjacent repea-
ters must be interconnected at the start and end of
every such line. This avoids individual “excessively
long“ fiber-optic line sections.

This network topology is used in the case of an optical
link between data terminal units or bus segments.
A maximum of 20 repeaters can be operated in an
optical line.
The first and last repeater in the line must be termi-
nated with an “optical short-circuit“ (see Fig. 4).
In this case, each input and output of the free ports
are connected to BFOC connectors via a short length
of optical cable.

Observe the following safety precautions:
©The shielding of the Sub-D connector is made of
metal to ensure safe ground current conduction
and must therefore be conductively connected to
the shielding plate of the connector attached to
the cable.
©FIP bus lines must not be used to connect FIP
repeaters to system components to which a
different ground potential is being applied.
Voltage differences > 500 V could destroy the
repeaters or cause the system to malfunction!
©FIP bus lines which are completely or partially
installed outdoors should not be connected,
otherwise any lightning strikes in the immediate
vicinity could destroy the repeaters. Optical cables
should be used for bus connections which are
routed out of buildings!
©The FIP repeater should only be supplied with a
regulated safety extra-low voltage to IEC 950/
EN 60950/VDE 0805 of +24 V to max. +48 V +10%.
©To enhance operational reliability, a redundant
supply from various sources is provided. The
operating voltages can be supplied in two ways:
– via terminal +24 V/48 V of the terminal block
– via terminal +24 V/48 V* of the terminal block
The common negative connection in the middle of
the terminal block is indicated by m.
©The two voltages can have any (even different)
values within the specified limits of +24 V/+48 V.
©If no signaling contact lines are connected to the
terminal block (see 3.7):
Secure the terminal block by screwing on the
flange.
