1Product overview
The Flashlink MR-TR-MkII is a multi bit-rate converter and transponder module providing
high performance media conversion for various signal formats from 19.4Mbps up to
1485Mbps. The unit can be configured as an
−Electrical to Optical or an
−Optical to Electrical converter, or as an
−Optical to Optical Transponder.
This state of the art unit offers a high sensitivity PIN diode and 1310/1550nm or CWDM
laser technology. Unmatched signal accuracy, even in critical applications with pathological
signal patterns makes the MR-TR-MkII the first choice for all optical transport demands.
The Flashlink CWDM system uses only wavelengths in accordance with the ITU-T G.694 from
1270±6nm up to 1610±6nm.
The MR-TR-MkII can transport all HD and SD signal formats in addition to DVB-ASI and
SMPTE 310. It can perform optical refreshing, reclocking and wavelength swapping for a
CWDM wavelength for SDH/SONET and Gigabit Ethernet in addition to all the broadcast
signal formats.
The input sensitivity is typically better than –25dBm. This will allow for a range of 50km,
using high quality Single Mode fibre at 1485Mbps, for a 16 channel CWDM system.
MR TR C1xxx comes with DFB CWDM lasers from 1270±6nm up to 1610±6nm. The open
system platform of Network Electronics CWDM multiplexing technology allows easy
interoperability with third party fibre optical systems.
The electrical input is equipped with a multi rate cable equaliser providing an equalisation of
typically 100m of high quality coax cable at 1485Mbps. A distribution amplifier with 2
outputs reduces the need for additional DAs (for DVB-ASI only one can be used).

4Connector module / backplane
The MR-TR has a dedicated backplane: MR-TR-C1. This module is mounted at the rear of the
sub-rack. The module is shown in the figure below.
Figure 7: Backplane for MR-TR.
In typical use an MR-TR module at each end will be used. The electrical input signal is
connected to the INPUT BNC on the transmitting MR TR, and the electrical output is
connected to the OUTPUT 1 or OUTPUT 2 BNC on the receiving MR-TR. Please note that
OUTPUT 2 has an inverted signal, so formats like DVB-ASI can not use this output.
4.1 Mounting the connector module
The details of how the backplane is mounted, is found in the user manual for the Flashlink
frame FR-2RU-10-2.
This manual is also available from our web site: http://www.network-electronics.com/

1MR-TR has a “Transparent mode”. In this mode all reclockers and CDRs are switched off and no jitter
attenuation will be performed. This mode may be used for non-standard or unsupported bit rates over
shorter distances and up to 1 Gbps.

5Module status
The status of the module can be monitored in three ways.
1. GYDA-SC System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LEDs at the front of the sub-rack.
Of these three, the GPI and the LEDs are mounted on the module itself, whereas the GYDA-
SC System Controller is a separate module giving detailed information on the card status.
The functions of the GPI and the LEDs are described in sections 5.1 and 5.2. The GYDA
controller is described in a separate user manual.
5.1 GPI Alarm – Module status outputs
These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector outputs, sinking to ground when an alarm is triggered. The GPI
connector is shown in figure below.

5.2 Front panel – Status monitoring
The status of the module can be easily monitored visually by the LEDs at the front of the
module. The LEDs are visible through the front panel as shown in the figure below.

6Laser safety precautions
These are guidelines to limit hazards from laser exposure.
All the available EO (including ETH100) units in the Flashlink range include a laser.
Therefore this note on laser safety should be read thoroughly.
The lasers emit light at wavelengths from 1270nm up to 1610nm. This means that the
human eye cannot see the beam, and the blink reflex cannot protect the eye. (The human
eye can see light between 400 nm to 700 nm).
A laser beam can be harmful to the human eye (depending on laser power and exposure
time). Therefore:
Be careful when connecting / disconnecting fibre pigtails (ends).
Never look directly into the pigtail of the laser/fibre.
Never use microscopes, magnifying glasses or eye loupes to look into a fibre end.
Use laser safety goggles blocking light at 1310 nm and at 1550 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
Flashlink features:
All the laser module cards in the Flashlink product range, are Class 1 laser products according
to IEC 825-1 1993, and class I according to 21 CFR 1040.10 when used in normal operation.
More details can be found in the user manual for the FR-2RU-10-2 frame.
Maximum output power2: 5 mW
Operating wavelengths: > 1270 nm
2Max power is for safety analysis only and does not represent device performance.
