What is the optical module for
Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The optical module is also called a fiber optic transceiver, which is mainly used for photoelectric conversion of signals. At the transmitting end, the electrical signal of the device is converted into an optical signal, and at the receiving end, the optical signal is restored to an electrical signal. The optical module is composed of a laser at the transmitting end, a detector at the receiving end, and electronic devices for data encoding/decoding.

What is the principle of optical communication?
The principle of optical fiber communication is: at the sending end, the transmitted information (such as voice) must first be converted into an electrical signal, and then modulated onto the laser beam emitted by the laser, so that the intensity of the light changes with the amplitude (frequency) of the electrical signal. And send it out through the optical fiber; at the receiving end, the detector converts the optical signal into an electrical signal after receiving it, and restores the original information after demodulation.

Who knows the basic equipment composition and function of optical communication?
Optical communication is the communication using light waves as the carrier. With the advent of the information age, people's demand for optical communication bandwidth is increasing. There are two ways to increase the bandwidth of the optical path: one is to increase the single-channel transmission rate of the optical fiber; the other is to increase the number of wavelengths transmitted in a single optical fiber, that is, wavelength division. Multiplexing technology (WDM).

Principle of laser communication
Laser communication is a communication method that uses laser light to transmit information. Laser is a new type of light source, which has the characteristics of high brightness, strong directionality, good monochromaticity, and strong coherence. According to different transmission media, it can be divided into atmospheric laser communication and optical fiber communication. Atmospheric laser communication is laser communication using the atmosphere as a transmission medium. Optical fiber communication is a communication method that uses optical fibers to transmit optical signals.
