Optocoupler to light as a medium to transmit electrical signals. Its input and output have a reliable electrical isolation, so it is widely used in a variety of circuits. Currently, it has been one of the most species, the most widely used in optoelectronic devices. fiber optic manufacturer in china
 
Optocouplers generally is composed of three parts: the emitted light reception and signal light amplification. The input electrical signal driving the light emitting diode, so that given a certain wavelength of light is received by the photodetector generates a photocurrent, and then after further amplified output. Unidirectional signal transmission, the input and output of the full realization of the electrical isolation, the output signal does not affect the input side, anti-interference ability, stable, non-contact, long life, high transmission efficiency. best fiber optic cable
 
Optocoupler is developed in the 1970s produced new devices, is now widely used in electrical insulation, level shifting, inter-stage coupling, drive circuit, switching circuit, chopper, among multivibrator, signal isolation, isolation level, pulse amplification circuitry, digital instrumentation, long-distance signal transmission, pulse amplification, solid state relay, instrumentation, communications equipment and computer interfaces. Many people want to buy fiber optic patch cord.In the single-chip switching power supply, using a linear optocoupler feedback circuit may constitute, by adjusting the control terminal of the current to change the duty cycle to achieve the precise purpose of regulation.
