19.5 Fiber reception after coupler
The optical option makes it possible to make measurements after terrestrial coupler / sat at the output of the
fiber.
Example of installation:
To display the signal at the output of your installation, you must connect the RF output of the optical option
to the RF input of the appliance via the provided angled F/F cable. Power your coupler (no external power
supply is provided with the measurement appliance).
Remove the protective plug from the FC APC optical socket; if required, use the provided jumper cable, and
connect the optical fiber from your dish to the same socket.
Then, you can turn your dish (see chapter
2.2.3 Installation of a dish
) and/or your terrestrial antenna (see
chapter
2.2.2 Installation of a terrestrial antenna
).
Once the measurements are made,
put the plug onto the
optical socket
of the appliance.
Warning: The appliance can measure only one wavelength at a time. If there are several wavelengths,
measurements will be wrong.
You’d better check the optical power of the coupler before processing (
