Optical Signal Generator

The OPG (Optical Pulse Generator) converts electrical signals pulses into optical signals with the same temporal shape. The optical signals are carried by a single mode fiber to the fiber adapter on the panel. Connecting single mode fiber, the signal can be sent to near or far places with no need of alignment of mirrors and lenses. The spatial shape of the signal is almost a perfect Gaussian beam with 9 micrometers width – a point source. A fiber collimator can be connected; converting the output beam into a collimated beam. Signals up to 100MHz and pulses down to 4 nanoseconds can be converted...

Optical Delay Line

The ODL module convert RF signals to optical signal and back, performing a desired time delay of input RF signals at 0.1-15 GHz region (20GHz is optional).
The RF input signal is converted into an optical modulated signal, which is then transmitted into a single mode fiber, creating a fixed time delay. After passing the fiber, the optical signal is converted back into an electrical RF signal.
ODL modules with time delays between 0.01 to 200 µsec can be provided to customers. The electrical control on the ODL is done automatically by a PC, with no need for any intervention of the operator...

RF over Fiber

Fiber Optic transmission is the most efficient means to transmit RF signals over long distance. Fibers show a lower signal loss, are lighter and less expensive than coaxial cables. Light from a laser diode is modulated by the RF signal either by direct modulation of the injection current into the laser diode or by an external modulator, thus converting the electronic RF signal into an optical signal...
