This strategy enables the video signal to be transmitted more efficiently through long distances. Then, the carrier will “carry” the information in the form of radio frequency (RF) signal.
How does an optical modulator work?
An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre). This sort of modulation is called direct modulation, as opposed to the external modulation performed by a light modulator.
How do you hook up AV modulator?
Connect a separate coaxial cable from the TO TV jack on the RF Modulator to the RF input jack on the TV. If you do not have an RF TV source, connect a coaxial cable from the TO TV jack on the RF Modulator to the RF input jack on the TV.
