Optical receiver

This device is capable of detecting a modulated light input signal and demodulating it by converting it into an electrical signal of a frequency corresponding to the input frequency. Thus, the set of modulable laser diode and optical receiver allows for a complete set of data transmission through light, from emission to reception. The efficiency of optical fiber guidance can be demonstrated by showing that without optical fiber, the maximum distance between the transmitter and the receiver is very short. The signal frequency must be between 0 and 1 kHz and can be read on the optical receiver. The higher the frequency, the greater the number of LEDs lit up. The student visually verifies that the emitted frequency is accurately reproduced. LED 1 of the bargraph lights up at 100 Hz. Two secure sockets allow visualization of the output signal. Comparing the input signal with the output signal highlights the transmission of information through laser diode by preserving the signal frequency. To be completed with the modulable laser diode (see related products).
