OPTICAL INPUT:
SC-APC input connector for the optical receiver. Used for the fibre link for the
satellite polarisation and TV signals.
TV+SAT OUT:
4 F connectors for mixed TV+SAT outputs (87 - 862MHz, 950 - 2150MHz)
Aerial system earth connection (according to EN60728-11 standard)
POWER ON LED:
On (green) to show the product is turned on.
Aerial system earth connection
(according to EN60728-11 standard).
System Functions:
The headend system in a fibre optic distribution network uses traditional receptive devices, i.e.
aerials, dishes and traditional LNB’s and any signal equalisation and amplification units.
TV and SAT signals are sent to an OPT-TX DT optical transmitter, which converts the electrical
signals into luminous signals, therefore enabling the distribution via a fibre optic infrastructure
over long distances.
Like traditional systems, each time this signal has to be split over a number of lines, a device called
an optical divider or optical splitter (VOV or VOT) is used this splits the signal into a number of
optical transport lines without any fall in quality even with a calculated attenuation.
Once the optical signal is in the vicinity of the unit to be served, it is reconverted into a traditional
signal by the OPT-RX DT optical receiver which on output generates the RF signals provided to the
end user by means of traditional components (coaxial cables and filtered outlet sockets).
3. PRODUCT INSTALLATION
ATTENTION:
A direct optical connection cannot be made between the OPT-TX DT
and OPT-RX DT
. The connection can only be made using optical line attenuators as the overall
input power to the OPT-RX DT optical receiver must not exceed -7dBm.
Check the optical level of the signal on the fibre using an optical light meter
before connecting it to the OPT-RX DT receiver
.
