Converter serial interface – optical fibre
ODW-622 is a fibre optic modem that converts between electrical RS-232 and a fibre
optical link.
ODW-622 can also be used to convert from RS-232 to RS-485 by using a
ODW-622 in the same link as ODW-632.
Repeater – optical fibre links
ODW-622 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 electromagnetic
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.

ODW-622 converts data using rates from 300 bit/s up to 250 kbit/s. Retiming of the data
ensures that the correct signal form is transmitted from the ODW-622 converter.
Designed for harsh environments, such as industrial, road and railway
applications
ODW-622 complies with standards for industrial environments and railway signalling and
telecommunications apparatus. Additionally, the wide climatic range of the ODW-622
allows it to be installed in out-door cabinets without any additional measures, such as
heating, etc.
Redundant ring via fibre optical network
Under normal operation the serial data is sent over ring A. Should a fault be detected on
the fibre ring then the data will be carried on rings A and B.
Ring A
Ring A Ring A Ring A
Ring B Ring B Ring B
Ring B
Note! Ring A start up at TX (channel 1) and ring B ends up at RX (channel 1).
… Normal operation, data exchange between serial master and slave.
• ODW-622 unit connected to the PLC master receives serial data at the electrical
port, it converts and transfers this master frame via the fibre ring A. At this unit, the
repeating of transferred frames is stopped until this transferred master frame has
returned via 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 serial data and send it via the
electrical port.
• ODW-622 unit, to which the addressed Slave is connected, receives serial data from
the Slave. This unit converts 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.
Page 10

6650-2234
• When the “first” ODW-622 unit receives the master frame (the same frame that has
been transmitted by this unit), or after a timeout, data conversion will be allowed
again. The received slave frame will be converted and transmitted at the electrical
port.
• When the ODW-622 unit, connected to the PLC slave receives the slave frame (the
same frame that has been transmitted by this unit), or after a timeout, data conversion at this unit will 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 (local unit). During that time, the transferred data frames
should be seen as corrupted or missed.
Note: Be ware of that full duplex will not work in redundant ring.
Failure Indications
Fibre interruption ring A, TX On: FL R
Fibre interruption ring A, RX On: FL L
Fibre interruption ring A, RX & TX On FL L
Fibre interruption ring B, TX On: FL R
Fibre interruption ring B, RX On: FL L
Fibre interruption ring B, RX & TX On: FL L
Fibre interruption ring A and B
(e.g. CH1 or CH2 both TX & RX)
Low power on the receiver (May indicate bad fibre) FLL flicker
On: FL L &/or FL R
… Recovery from faulty status
• ODW-622 will automatically recover to the previous operating status when a failure
disappears. This involves recovery from multi drop 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.

The data is transferred via the fibre optic network to the serial ports of all units. If
ODW-622 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-622 optical fibre port will be repeated through the other optical fibre
port and it will also convert the frame to serial data.

Example
• Redundant ring, one data exchange between master and one slave.
One a master and 11 slaves with data rate 9600 bit/s dependent mode. 12 ODW-622 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
(excluded the two units connected to PLC master and slave).
10 x 3.0 µs = 30 µs
3. Converter electrical to fibre:
Signal processing delay x 2
(ODW-622 units connected to a master and addressed slave).
(1 t
+ 0.6 µs) x 2 = (105 µs + 0.6 µs) x2 = 211 µs
bit
4. Converter fibre to electrical:
Signal processing delay x 2
(units connected to PLC master and slave).
0.6 µs x 2 = 1.2 µs
5. The system delay is calculated by summing the delays in item 1 to 4 above:
200 µs + 30 µs + 211 µs + 1.2 µs = 442 µs

* To minimise the risk of interference, a shielded cable is recommended when the cable is located inside 3 m
boundary to the rails and connected to this port.
The cable shield should be properly connected (360°) to an earthing point within 1 m from this port.
This earthing point should have a low impedance connection to the conductive enclosure of the apparatus
cabinet, or similar, where the unit is built-in. This conductive enclosure should be connected to the earthing
system of an installation and may be directly connected to the protective earth.
Optical Power Budget
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 ageing (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 transmitter’s output optical power (min) and the receiver input sensitivity (max).
