2. PRODUCT DESCRIPTION
Optical transmitter (OPT-TX DT) and optical receiver (OPT-RX DT) for distributing satellite and digital
terrestrial signals through a single-mode fibre optic cable.
The incoming RF signals to the OPT-TX DT transmitter are converted and distributed through a
single-mode fibre optic that can be split by splitters and passive taps enabling them to be sent to
multiple optical connections (PON=Passive Optical Network) using a single transmitter.
The OPT-RX DT receiver converts the incoming optical signal in to 4 universal outputs, therefore
enabling the TV and SAT signal to be available for 4 different users, with all the services and products
offered by the broadcaster, as if they were directly connected to an independant aerial or dish.
The system requires the use of a conventional LNB and provides a traditional 5 core output (4 SAT
+ 1 TV) to enable a cascadable installation to additional transmitters or to a traditional multiswitch
system.
The AGC (Automatic Gain Control) in the transmitter makes the product configuration much easier
by automatically adjusting the input signal level to the optical laser.
SAT INPUT:
F input connectors for the four IF satellite polarities (950 - 2150MHz) with LNB
remote power
TV INPUT:
F input connector for the TV signal (87 - 862MHz)
TEST SAT: F output connector for the SAT test signal, HH polarity (RF level: 60dBµV per transponder)
TEST TV: F output connector for the TV signal 87 - 862MHz (RF level: 74dBµV overall power)
OPTICAL OUTPUT:
SC-APC output connector for the optical transmitter for the fibre link
SAT OUTPUT: F output connectors for the four IF satellite polarities (950 - 2150MHz) for possible
cascade applications to other devices
TV OUT : F output connector for the TV signal (87 - 862MHz).
POWER ON LED:
On (green) to show the product is turned on.
ALARM LED: the alarm LED shows that the transmission laser is not working correctly.
Earthing the antenna installation (according to EN60728-11 standard).
