Function of Optical Couplers 6
Optocouplers are very useful when you need to isolate different sections of a circuit, for example in power supply circuits to transfer signals between high-voltage and low-voltage areas, preventing damage to sensitive components. Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can. In this guide, you'll learn how they work and how you can use one in your own projects. Image alt: Optocoupler-Optical coupler The figure above depicts a 2x2 coupler with two input ports and. Thus, for example, these couplers are fabricated of lithium niobate via surface diffusion from a local titanium source or those fabricated of Si, including Si wires.
