Introduction

The FXURLEN74YNM022 application field and working principle refers to the optical communication system, which refers to the technology of transmission and reception of information by using optical radiation as the carrier. It is the information transmission technology that has been developed rapidly with the rapid development process of the communication industry. It has a wide range of application in the fields of mobile communication, terrestrial trunk communication, optical fiber access network, and optical fiber multimedia.

Application Field

Optical communication systems are widely used in mobile communication due to their wide coverage, high speed and low cost. In the mobile communication network, the base station communicates with the user equipment. Optical fiber communication is used in the relay link between the base stations and the user equipment to improve the signal transmission rate and reduce the interference due to the diversity of the communication path. The optical fiber is connected between the base station and the user equipment to replace the relay link provided by microwave or millimeter wave. In this way, the transmission rate of the signal can be improved and the communication capacity of the system can be improved.In terrestrial trunk communication, long-distance transmission of voice, data and video information is mainly realized by using optical fiber communication technology. In order to reduce the influence of electromagnetic interference on communication and the related crosstalk generated by signal transmission, the transmission rate and the transmission distance of optical fiber are increased to form a new generation of trunking communication system. This type of communication utilizes wavelength division multiplexing technology to achieve high spectral efficiency and reduce the number of optical fibers and electrical amplifiers needed to support the trunking network, thereby reducing costs.In the optical access network, optical fiber communication technology is widely used for local area network access and high-bandwidth data services such as broadband video. This type of communication uses wavelength division multiplexing technology to multiplex multiple channels of voice, data and video signals into an optical fiber to provide high-bandwidth access services to multiple connected users.In the optical fiber multimedia system, vertical optical fiber communication technology is used to provide multiple services such as voice, video and data in a single optical fiber. This type of communication can provide more services and functions with low cost than traditional communication systems.

Working Principle

The working principle of the optical communication system is to transmit and receive information by using light optics as the carrier. The information to be transmitted is converted into optical signal or pulse of certain wavelength by the transmitter, and then the optical signals are amplified, routed and adjusted along the path of the optical fiber to the receiver. At the receiver, the optical signal is converted into electrical signal or pulse, and then the information is extracted according to the characteristics of the signal.The optical source used in the system can be any type of light, including semiconductor lasers and LEDs. The laser is used to generate an optical signal with a precise wavelength and single-mode output, which is suitable for long distance signal transmission. LEDs, on the other hand, are used to generate a wavelength of optical signals with high output power and multi-mode output, which is suitable for short distance communication.The optical signal is transmitted in the form of optical pulse or optical wave, which is transmitted along the optical fiber and attenuated due to optical scattering and other factors along the way. In order to ensure the integrity of the signal, the optical power must be amplified from time to time. A variety of optical amplifiers are used to achieve this purpose, such as erbium-doped fiber amplifier (EDFA), Raman amplifier, and semiconductor optical amplifier (SOA).Finally, the optical signal received by the receiver is converted into electrical signal or pulse, and the information is extracted according to the characteristics of the signal. The information received can be further processed, displayed or stored for further use.

Conclusion

The FXURLEN74YNM022 application field and working principle is a technology that uses optical radiation as the carrier for the transmission and reception of information. This technology has a wide range of applications in mobile communication, terrestrial trunk communication, optical fiber access network, and optical fiber multimedia. Its working principle is to convert the information to be transmitted into optical signals, amplify, route and adjust them along the optical fiber path to the receiver, and then extract the information from the optical signal received by the receiver.
