8947RDA-D/-FR SD/HD
Reclocking DA Modules
Introduction
This manual covers installation, configuration, and operation of the
8947RDA-D Dual SD/HD Reclocking DA and the 8947RDA-FR SD/HD
Reclocking Fiber Ready DA, both of which must be installed in a Grass
Valley GeckoFlex frame.
The 8947RDA-D is a dual SD/HD re-clocking distribution amplifier with
automatic format detection. It provides four (in dual mode) to eight (in
single mode) reclocked outputs and can equalize up 125 meters of Belden
1694A cable for HD-SDI. It can be used to distribute either SD-SDI or
HD-SDI making it ideal for mixed format applications or installations
where an upgrade is planned. It requires the 8900WE-R rear module.
The 8947RDA-FR is a fiber-ready reclocking distribution amplifier with
automatic format detection. It provides eight reclocked electrical pouts and
can equalize up to 125 meters of Belden 1694A cable for HD-SDI. In addi-
tion, the module supports fiber optic inputs and outputs when an optional
fiber optic SFP device is installed.
One of three SFP devices can be used: Dual Transmitter (two fiber optic out-
puts), Dual Receiver (two fiber optic inputs), or Transceiver (one fiber optic
input and one fiber optic output). It requires the 8900WFR-R rear module.
The modules can also distribute eight non-inverted DVB-ASI outputs
making them ideal for receiving signals from distant downlinks or trans-
mitting to remote uplinks.
