Brief instruction FLEXtra® FO 650
Application and functional description
The FLEXtra® FO is primarily a normal PROFIBUS
repeater with the capability of expansion by 2 (with
FO-2) or 5 (with FO-5) additional optical MPI/PROFIBUS
segments.
It translates an electrical MPI/PROFBUS interface into an
optical MPI/PROFIBUS interface and vice-versa.
It regenerates the edge steepness, level and duty cycle
of signals. In addition it brings the advantages of
optical signal transfer to the MPI/PROFIBUS network.
The Flextra FO are available in 3 different variants:
(Suitable for POF resp. PCF2))
FLEXtra® FO 650-2:
Connector type BFOC1) resp. ST, 650 nm 700-996-2AA01
Connector type SMA, 650 nm 700-996-2BA01
Connector type Versatile Link3) resp. HP, 650 nm 700-996-2CA01
FLEXtra® FO 650-5:
Connector type BFOC1) resp. ST, 650 nm 700-996-5AA01
Connector type SMA, 650 nm 700-996-5BA01
Connector type Versatile Link3) resp. HP, 650 nm 700-996-5CA01
1. The FLEXtra® FO is suitable for mounting on a DIN
rail. It is engaged as shown in the picture.
2. A DIP switch is installed for deactivating the repeat
function on the individual ports.
Furthermore, the DIP switch DIP 4 (FO-2) or DIP 7
(FO-5), can be used as the ON / OFF switch for all
segments.
With optical ports, switching off a port does not mean
that the send diode (Tx) is switched off, rather that the
port can no longer receive data at the Rx input. Hence
the repeater function of the port is deactivated.
Brief instruction FLEXtra® FO 650
3. If port X1 of the FLEXtra® FO is at the start or end of
a segment then termination on the POFIBUS connector
must be switched on (ON).
If port X1 of the FLEXtra® FO is in the middle of a
segment then termination on the PROFIBUS connector
must be switched off (OFF).
The PROFIBUS is connected to the FLEXtra® FO via the
SUB-D female connector. Connection of the optical seg-
ment is, dependent on type, via BFOC1) resp. ST, SMA
or Versatile Link3) resp. HP connectors.
Termination is not required for the optical ports.

OFF
4. Connect the optical bre cables to ports X2 – X5 of
the device. The following bres can be used:
• Polymeric Optical Fibre (POF):
• 980/1000 μm
• Wavelength: 650 mm
• Loss approx 160 db/km
• Polymer Cladded Fibre (PCF2) resp. HCS):
• 200/230 μm
• Wavelength: 650 mm
• Loss approx 10 db/km
Note: For the assembly are separate connectors, and
special assembly tools according to the required plug
connection technology required.
The information on installation to a POF type please refer
the steps A to C (see reverse side).
You may obtain the necessary ber cable completely pre-
assembled from your FO supplier.
Connect the optical ports via a CROSS-OVER connec-
tion i.e. TxD bre of the other end to the RxD connector
of the FLEXtra® FO.
Connect RxD bre of the other end to the TxD connec-
tor of the FLEXtra® FO.

C) Connecting the connector to the bre
BFOC1) resp. ST or SMA connector:
Slide the connector over the bre and screw the
connector housing on with the lock nut.

sing sides together until they lock.
Note: When attaching the connectors, make sure that the
ber ends ush with the connector at the front.
The transmit or receive diode may be damaged if the ber
protrudes.
Fixing the ber too far inward can result in increased
attenuation, shortening the transmission range of the
system.
