Figure 1: MR-TR-3G-D Multi rate transponder for DWDM
This Flashlink MR-TR-3G-D15xx.xx is a multi bit-rate converter and transponder providing
high performance media conversion and re-clocking for SDI, SDTI and DVB-ASI signal
formats from 270Mbps to 2.97Gbps. The optical ports also provide support for SDH/SONET
and 1000Base-LX formats allowing for transponding and regeneration of optical signals.
Other signal rates from 19.4 to 2970Mbps are also supported in non-reclocked mode. The
Flashlink MR-TR-3G-D15xx.xx module can be configured as an electrical to optical and
optical to electrical converter, also called add-drop. It can also be configured as an optical to
optical transponder. It can perform optical refreshing, re-clocking and wavelength swapping.
The module offers a high sensitivity optical receiver and a narrowband temperature stabilized
0dBm or +5dBm DWDM laser. The module can be controlled, monitored and upgraded from
GYDA.
The Flashlink DWDM system uses wavelengths in accordance with the ITU-T G.694.1
recommendation. The exact wavelength needs to be specified.
The electrical input is equipped with a multi rate cable equalizer providing an equalization of
typically 70m of high quality coax cable at 2970Mbps. A distribution amplifier with 2 outputs
reduces the need for additional DAs (for DVB-ASI only one can be used).
