Typical Applications - Fracarro KTX Mode D'emploi

ATTENTION: WHEN THE GREEN LED
(ON) IS LIT THE LASER IS POWERED
AND IS EMITTING INVISIBLE LASER
RADIATION.
On the KTX module the connector identified
as RF-INPUT represents the input for the
downlink signal from 47 to 2150MHz (usable
for a forward path application using 47 -
862MHz for TV signals and 950 - 2150MHz for
one IF SAT band for example). It is also
possible to use the module for the transmission
of a single TV or SAT band.
On the front of the module the green LED
(ON) lights up when the product is correctly
powered. The red LED (ALARM) lights up if
there is a possible fault with the transmitter for
example too high current absorption by the
laser (which indicates damage to the
incoming laser), or the absence of an optical
output (which indicates a break in the laser).
Fig.3 illustrates a typical installation of a forward path link using return path optical fibre solutions. The optical
link is designed to transport forward path RF signals (from 88MHz up to 2150MHz) over fibre. The product is
fully compatible with the return channel optical link using the KTX-RC and KRX-RC.

On the KRX module the connector identified as
RF-OUTPUT represents the output for the
downstream signal from the headend
transmitted by the KTX. The bandwidth of the
received signal is the same as that at the input
of the KTX module.
On the front of the module the green LED (ON)
lights up when the product is correctly powered.
The red LED (ALARM) lights up if there is a
possible problem with the receiver for example
optical input power is too low.
