Converter PROFIBUS DP – optical fibre
ODW-612 is a fibre optic modem that converts between electrical PROFIBUS DP and a
fibre optical link.
Repeater – optical fibre links
ODW-612 is a fibre optic repeater that repeats received data from one fibre link out
to the other link.This is useful e.g. for long distance communication, where electromag-
netic interference may occur or when isolation of the electrical network is needed.The
maximum optical fibre distance depends on selected fibre transceiver and fibre type.
Distances up to 80 km (50 miles) are available.
Data rate up to 12 Mbit/s
ODW-612 converts PROFIBUS DP data using data rates from 9 600 bit/s up to
12 Mbit/s. Retiming of the PROFIBUS DP data ensures that the correct signal form is
transmitted from the ODW-612 converter.
Automatic data rate detection
The PROFIBUS data rate is set automatically as soon as the ODW-612 receives a
correct data frame, whether data is received from PROFIBUS DP or the fibre optic link.
The detected data rate remains until a number of consecutive faulty received frames have
been detected or no further frames are detected within the timeout period. The time-
out period is set by switches, with the default setting of one faulty frame or 65 535 tbit
without any received frame.

Redundant ring via fibre optical network
Under normal operation the PROFIBUS DP data is sent over ring A.
Should a fault be detected on the fibre ring then the PROFIBUS DP data
will be carried on rings A and B.

… Normal operation, data exchange between PROFIBUS DP master and slave.
• UnitMreceives PROFIBUS DP data (from a Master) at the electrical port, it converts
and transfers this master frame via the fibre ring A.
At unitM, the repeating of transferred frames is stopped until this transferred master
frame has returned to unitMvia ring A.
• This master frame will be repeated through fibre ring A by all the other units. Each
of these units will also convert the master frame to PROFIBUS DP data and send it
via the electrical port.
• UnitS, to which the addressed Slave is connected, receives PROFIBUS DP data from
the Slave. UnitSconverts slave data and transfers the slave frame via ring A.
The repeating of transferred frames is stopped until this transferred slave frame
has returned via ring A.
• When unitMreceives the master frame (the same frame that has been transmitted
by this unit), or after a timeout, data conversion at unitMwill be allowed again.
The received slave frame will be converted and transmitted at the electrical port.
• When unitSreceives the slave frame (the same frame that has been transmitted by
this unit), or after a timeout, data conversion at unitSwill be allowed again.
… Behaviour under faulty conditions
• Elapsed time from any kind of failure at the fibre optic network until data exchange
after a corrective action depends on total length of fibre ring.
This is typically 40–500 ms. During that time, the transferred data frames should be
seen as corrupted or missed.

… Recovery from faulty status
• ODW-612 will automatically recover to the previous operating status when a failure
disappears.This involves recovery from multidrop application to Redundant ring A/B
when ring is up and running and recovery from Ring B to Redundant ring A when
the ring is up and running.
• The time to recover from the failure status depends on total length of fibre ring.
This is typically 40–500 ms. During that time the transferred data frames should be
seen as corrupted or missed.
Multidrop via fibre optical network
The electrical PROFIBUS DP network is transferred via the fibre optic network to the
electrical ports of all units. If ODW-612 is connected to two optical fibre links (mid unit)
converted data will be transmitted in both directions, via both CH 1 and CH 2.
With only one optical fibre link (end unit) converted data will be transmitted in one
direction, via CH 1 only. Data received from one ODW-612 optical fibre port will be
repeated through the other optical fibre port and it will also convert the frame to
PROFIBUS DP data and send it via the electrical port.

Optical fibre link functionality and status indication
At power on, all LED's will be active during an initiation sequence followed by an auto-
matic initiation of the optical fibre links.The alarm will be set until the fibre optical links
are in operation and ready to transfer PROFIBUS DP data.
Data frames are transferred over the fibre optic links as long as the links are in operation
and the data rate has been detected.
When any of the fibre optic links is out of operation, this will be indicated by a
local alarm, and this will set the alarm output. It will also send a remote alarm via the
other link, if possible.When the link returns to operations mode, the alarm will reset
automatically.
The Bus active (BA) LED is set if data frames are received on the electrical
PROFIBUS DP or fibre optical port and the data rate is detected, independently
of the status on fibre optical link.
Redundant power supply, galvanic isolated (2 kVAC) to other ports
ODW-612 should be supplied with safety extra low voltage (SELV). It is designed to
operate permanently over a wide input range and provided with two independent inputs,
allowing redundancy should either supply fail.
9-position D-sub PROFIBUS DP connector
The pin assignment for the connector is in compliance with PROFIBUS standard
EN 50 170
Single or multimode LC fibre connectors
ODW-612 use Small Form Factor Pluggable (SFP) transceivers that are in compliance
with the Multi-Sourcing Agreement (MSA).This means that a wide range of different
fibre transceivers and connectors can be used.
Status interface
This interface enables supervision of fibre optic link state by means of a relay with both
normally open and closed contacts.
The fault state will be set if:
… Local or remote fibre link errors exist.
… The unit is out of service, e.g. no power supply.
Designed for hash environments, such as industrial, road
and railway applications
ODW-612 complies with standards for industrial environments and railway signalling and
telecommunications apparatus.Additionally, the wide climatic range of the ODW-612
allows it to be installed in out-door cabinets without any additional measures, such as
heating, etc.

Note t
bit = 1 / Baud rate (Baud rate in bit/s)
System delay in an optical network
Data exchange between a PROFIBUS DP master and slave via ODW-612 fibre optic link,
will be delayed due to the length of the optical fibre and the signal processing within the
ODW-612.The signal processing delay is dependent on the data rate, and the fibre delay
is dependent on the total length of the optical fibre.
There is no limitation of the total length of optical fibre for Multi-drop applications. In
Redundant ring applications the data transfer time in a ring is limited to 10 milliseconds.
This means the total length of the optical fibre ring is about 2 000 km, excluding the 1
microsecond delay at each optical repeater unit.
The additional time resulting from the optical fibre and ODW-612 is the Overall system
delay.The Redundant ring and Multidrop application Overall system delays differ, see
below.
… Redundant ring, one data exchange.
• The data exchange between PROFIBUS DP master and slave via ODW-612 fibre
optic link will run one direction through all units of the ring.The system delay is
calculated by summing the following:
1. Fibre: The total optical fibre ring length delay.
2. Optical repeaters: The optical repeater delay x Number of optical repeat-
ers (excluding the ODW-612 units connected to PROFIBUS DP master and
addressed slave).
3. Converter electrical to fibre: Signal processing delay x 2
(ODW-612 units connected to PROFIBUS DP master and addressed slave).
4. Converter fibre to electrical: Signal processing delay x 2 (ODW-612 units
connected to PROFIBUS DP master and addressed slave).

Multidrop, one data exchange.
• The data exchange between PROFIBUS DP master and slave via ODW-612 fibre
optic link will run from the ODW-600 units connected to PROFIBUS DP master
to the slave and the same way back to the master.The system delay is calculated by
summing the following:
1. Fibre: The optical fibre length PROFIBUS DP master to addressed slave
delay x 2.
2. Optical repeaters: The optical repeater delay * Number of optical repeaters
(excluding the ODW-612 units connected to PROFIBUS DP master and addressed
slave) x 2.
3. Converter electrical to fibre: Signal processing delay x 2
(ODW-612 units connected to PROFIBUS DP master and addressed slave).
4. Converter fibre to electrical: Signal processing delay x 2
(ODW-612 units connected to PROFIBUS DP master and addressed slave).
Example
• Redundant ring, one data exchange between master and one slave.
One PROFIBUS DP master and 11 slaves with data rate 1.5 Mbit/s. 12 ODW-612
units with a total fibre length of 40 km.A data exchange between master and one
slave.
1. Fibre: The total optical fibre ring length delay.
40 x 5 μs = 200 μs
2. Optical repeaters: The optical repeater delay x Number of optical repeaters
(excluding the ODW-612 units connected to PROFIBUS DP master and addressed
slave).
(12 – 2) x 1 μs = 10 μs
3. Converter electrical to fibre: Signal processing delay x 2
(ODW-612 units connected to PROFIBUS DP master and addressed slave).
(1 tBit + 1.0 μs) x 2 = (0.7 μs + 1.0 μs) x 2 = 3.4 μs
4. Converter fibre to electrical: Signal processing delay x 2
(ODW-612 units connected to PROFIBUS DP master and addressed slave).
0.3 μs x 2 = 0.6 μs
5.The system delay is calculated by summing the delays in item
1 to 4 above:
200 μs + 10 μs + 3.4 μs + 0.6 μs = 216 μs

Optical Power Budget
The maximum supported link lengths as specified in the table above should only been
seen as indicative.The allowed link length is calculated from the Optical Power Budget
(OPB), (the available optical power for a fibre-optic link), and the attenuation of the fibre,
comprising losses due to in-line connectors, splices, optical switches and a margin for link
aging (typical 1.5 dB for 1300 nm).
The worst-case Optical Power Budget (OPB) in dB for a fibre-optic link is determined
by the difference between the minimum transmitter output optical power and the lowest
receiver sensitivity.
* Output power is power coupled into a 62.5/125 μm multimode fibre.
** Output power is power coupled into a 9/125 μm singlemode fibre.
*** The optical power should be reduced by at least 5 dB (SM-LC80)
or 3dB (SM-LC80) between the optical output and input.
