5.1. AOM installation
1. Wear safety Googles
2. Wear a proper and working ESD wrist strap;
3. Caution : Set the module on a heat dissipating surface (an optical table works fine). Letting
the AOM in air with no dissipating surface leads to overheating and permanent damage.
4. The light can be inserted in any direction. The performance are the same (insertion loss,
extinction ratio etc.)
5. Caution : when using another RF driver, The RF power shall not be set over the maximum
diffraction efficiency level. A power over 2W can lead to a permanent damage. The RF
power must be adjusted progressively from 0 V up to the maximum diffraction level.
5.2. RF Driver installation
The product is dissipated by conducting heat. The product shall be mounted on a metal structure
using fixing screws. The mounting surface shall be flat with minimum size and thickness. A certain
amount of space should be reserved around and above the product.
The product is powered by a DC of + 24V, and the power connector is supplied with a per-centric
capacitor; The core of the heart capacitor is connected to the positive power supply, and the
grounding sheet of the heart capacitor is connected to the negative pole of the power supply.
The characteristic impedance of the product signal output port is 50 Ω.
The product receives both external pure analog and/or digital modulation.
The adjustment of RF output power is achieved by changing the resistance of a multi-turner : turn
clockwise to increase the output power, turn counterclockwise to decrease the output power.
1. Make sure the RF Driver has the correct RF frequency required by the AOM model (model
1 : 100 MHz, model 2 : 200 MHz, model 3 : 80 MHz ; model 4 : 200 MHz).
2. Make sure the RF Driver model is the one you need (TTL input or Analog input).
3. Connect the RF driver to the AOM with the SMA cable. If you use the modular model
RFAOM-TA-200, set the S1-S4 switch to the proper configuration (see below )
4. Caution : Place the module on a heat dissipating surface (an optical table works fine).
Letting the RF driver in air with no dissipating surface leads to overheating and permanent
damage.
5. Connect a 24V >0.5A power supply to the RF driver
6. Caution : The RF power shall not be set over the maximum diffraction efficiency level. A
power over 2W rapidly leads to a permanent damage. The RF drivers power level (little
