INTRODUCTION

Product description

The Optical Compact Headend converts Wideband/ CATV signals to multiple optical wavelengths. Thanks to built-in Automatic Gain Control (AGC) and Automatic Slope Control (ASC), the output signal is of optimal quality for your optical distribution system. The plugand-play Optical Transmitters are suited for many types of optical systems: up to 64 splits, up to 255 splits and even more than 2000 splits!

CONFIGURATION OF THE MODULE

CONFIGURATION

Select LNB Type:
With this switch you can select the frequency range of the Sat input signal. This is necessary to make the Automatic Slope Control (ASC) work properly. If signals of a Quattro LNB are inserted, then set the switch to “Q”. If Wideband signals are inserted, set the switch to “WB”.
Select # splits (only for REF. 4003):
With this switch you can select the number of splits in your system, this is necessary to make the Automatic Gain Control work properly.
Signal Quality LED:
The signal quality LED shows you the quality of the signal with different colors.
Orange Color: Signal level is too low. In this case, you should amplify the signal with an external amplifier.
Green Color: Signal level is within the AGC-supported range.
Red Color: Signal level is too high. You need to attenuate the signal with an external attenuator(s).
Solid LED: Slope is OK
Blinking LED: Slope is out of range
Set DC Supply and Laser Diode:
With this switch you can set the DC (18V) supply to the RF input and switch off the Laser Diode (LD) in order to measure each optical signal separately. To measure the signal strength of a certain wavelength, you need to switch off both other Laser Diodes.
Don’t forget to switch all LDs on after measurement.
The LED is off if no DC is supplied to the RF input and if no DC is supplied to the Laser Diode.
If no DC is supplied to the laser diode, the related signal is not converted into an optical signal.
Please make sure to switch on at least the laser diode for proper operation.
The LED is green if the Laser diode is switched on and the related output voltage off.
The LED is orange if the Laser diode is switched on the related output voltage is supplied to the RF input.
The LED is green/orange blinking if DC is supplied to the RF input and the device recognized a short circuit.
Optical output:
The optical transmitters each have an optical output power of +9 dBm per wavelength.
For REF.4003, make sure to set the select the right number of splits using the split switch.
