307792 Optical Headend Transmitter
Part
No.307792
Attention!
The installation and commissioning may only be performed by suitably qualified
persons, technicians or installers in compliance with safety regulations in EN
62368-1, EN 60825-1 (laser class 1) and EN 60728-11. Attention should also be
paid to the instructions and advice you find below.
Failure to comply with the specified precautionary measures may cause serious
injury to persons or damage to property. Damage due to improper installation
and commissioning, defective connectors on cables or any other incorrect
handling will void the warranty.
Disconnect mains power before working on electrical systems.
- A suitably qualified person should always install any additional electrical wiring requirements.
- Installation or service work should NEVER be undertaken during electrical / thunderstorms.
Waste Electrical and Electronic Equipment (WEEE) after end of life
- Do not dispose of these products in household waste! Dispose of them for recovery and recycling following the current National and European legislation and regulations.
Specific safety instructions
- The transmitter unit needs to be installed in a dry room or cabinet with sufficient air convection.
- Never connect the PSU to the mains before all cables have been connected to the transmitter.
- Never look in to an open core of a fibre cable or fibre connector that is in operation with a laser transmitter.
- Unfiltered Terrestrial antennas must not be connected directly to the TERR port.
- Un-used F-ports shall be terminated with DC blocked 75 Ohm terminators – like TRIAX DC Blocked Terminator 305349.
For potential equalization unit needs to be connected to the MET of the
building.
The grounding cable shall be fixed to the grounding clamp of the metal
housing.

Product introduction and specs
The new TOXT, Triax Optical Extra Headend converts Wideband/TERR signals to multiple optical wavelengths. Thanks to built-in Automatic Gain Control (AGC) and Automatic Slope Control (ASC), the output signal quality is optimal for your optical distribution system (9 dBm output power). The TOXT is suited for many types of optical systems: up to 64 splits, (32 Splits for FTTH) or can be easily be extended to many more!
- 2 Wideband and 1 TERR inputs
- frequency range: SAT: 290 — 2340 MHz (Wideband) / 950 — 2150 MHz (Quattro) / TERR: 40 — 1218 MHz
- 1 Optical output wavelengths 1350 — 1370 — 1550 (1310 — 1330 from optical loopthrough)

Configuration of the Headend
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:
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 the quality of the signal with different colours.
Orange Colour: 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
external attenuator(s).
Solid LED: Slope is OK
Flashing 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 of
the other. 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 is off.
The LED is orange if the Laser diode is switched on and the related output
voltage is supplied to the RF input.
The LED is flashing green/orange if the DC is supplied to the RF input and the
device recognized a short circuit.
Optical output:
The optical transmitter has an optical output power of +9 dBm per wavelength.
Make sure to select the right number of splits using the split switch.
Product installation
Dual SAT & TERR distribution over a single Fibre Optic Network (up to 64 Splits)
