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.
