optical signal transmission between electrically isolated networks
Utilizing light to isolate one control circuit from another; mainly used to safely interface a low level control signal to a high power output as in a solid state relay.
Communication devices may be damaged by inequality of ground voltage level when transmission line is long. Optical isolator is adopted to prevent from such damage and is able to transmit data at the same time.
Two networks which are connected only through an LED transmitter and photoelectric receiver with no electrical continuity between the two networks.
Two networks coupled only through an opto-electronic sender and receiver with no electrical conductivity between the two networks.
The technique of using an opto-electric transmitter and receiver to transfer data without electrical continuity. Provides an electrical barrier between related circuits to eliminate voltage differences and damages from transient power surges.
1) A method of protecting sensitive electronic circuits by using light emitters and receptors for the purpose of connecting with input and/or output devices. 2) A system in which sensitive electronic circuits are protected by light emitters and receptors.
