Operation safety
The TR-55 device was designed and tested for operation safety along with the PN-EN 60950
3rd class standard.
The device does not have an installed disconnecting system unit which should be
installed outside the device.
In case of a DC power supply to the device, an easily accessible disconnecting system
should be installed in the fixed wiring outside the device.
Radiation emitted by a laser transmitter is harmful to the eye
sight!
CLASS 1 LASER DEVICE
You must not look at an uncovered socket where no optic-fibre
joint is connected.
The producer is not liable for such use of the device that would not comply with the
operation manual.
The operation manual is an integral part of the device and is provided to users with the
device.

1. General Characteristics.
1.1. The View of Device
Figure 1. The device’s view
1.2. The Intended Use of Device
The TR-55 is a device used for point-point connections or connections in bus topology
between devices connected to one another with optic fibre and equipped with an interface
compatible with the RS-232, RS-422 or RS-485 standards. The converter can also operate in a
closed bus configuration – so-called “ring” – with protection (in case of damage to one of the
optic fibre connectors, transmission is switched to an alternative optic fibre path). The “ring”
connection is possible even for only two devices, thus there is a chance to transmit data with
point-point protection.
Specific versions of the device make it possible for the connection to use two fibres of a
single-mode or multi-mode optic fibre, or one fibre of a single-mode optic fibre in the WDM
technology. The TR-55 converter is fully compatible with the ITU-T V.24, EIA-422-B and
EIA-485 standards. The use of the TR-55 converter allows for building an extended net for
data transmission based on various transmission media.
Replacing an electric transmission medium with an optic fibre path provides for
extending the scope of transmission (even up to 50 km when using a single-mode optic fibre)
and eliminating the effect of such disturbing interactions as: electromagnetic field, stray
currents, ground potential differences, etc.
The latitude to configure an electrical port – independently in each converter along with
one of the three standards available (RS-232 or RS-422 or RS-485) enables us to match an
interface of data being sent between various types of devices, to which the converters will be
connected – without the use of additional appliances.

1.3. Symbol Marking:
TR – 55.W – X – Y (T)
Meaning of the abbreviations used:
MM – intended for cooperation with a Multi-Mode optic fibre
SM – intended for cooperation with a Single-Mode optic fibre
WDM - this version cooperates with a single fibre using the WDM 1310nm/1550nm
technology (Wavelength Division Multiplexing)
1310nm – transmitter working at the 1310 nm wavelength, receiver working at the 1310nm
wavelength
1310/1550nm – transmitter working at the 1310 nm wavelength, receiver working at the
1550nm wavelength
1550/1310nm – transmitter working at the 1550 nm wavelength, receiver working at the
1310nm wavelength
T - means the version of the converter which works
in extended temperature: -40C ... +75 C
device version:
1 – terminal converter (1 optical port)
2 – pass-thru mode converter (2 optical ports)
1-version with RJ-45 connector
2- version with the srew connector
optical interface type:
2 – 1310 nm SM/MM
5 – WDM 1310/1550 nm SM (only terminal)
6 – WDM 1550/1310 nm SM (only terminal)
7 – WDM 1310/1550 nm SM and 1550/1310 nm SM
