Ⅰ.Basic Concept of Fiber Optic Communication Technology

The essence of fiber optic communication technology is to use light as the primary carrier for information transmission, transmitting data information rapidly through light propagation in cables. From the current application of fiber optic communication technology, the use of optical fibers effectively solves the problems of data transmission speed and quality, ensuring that data can be transmitted at the fastest speed while guaranteeing the security and accuracy of data transmission. The main carrier of fiber optic communication technology is the optical waveguide fiber, which has light sensitivity and can maximize the effectiveness of light transmission. It is precisely because of these characteristics that fiber optic communication technology has widespread applications in the current communication field and multiple areas such as national defense.

Ⅱ.Main Advantages of Fiber Optic Communication Technology

From the current application of fiber optic communication technology, its main advantages are reflected in the following aspects:

1. Fiber optic communication has a large bandwidth and communication capacity.
2. Fiber optic communication has small signal attenuation, and the repeater distance is extended.
3. Fiber optic communication has strong anti-interference capability.
4. Fiber optic communication has higher information transmission security compared to other transmission methods.

III. Structure and Transmission Principle of Optical Fibers

Optical fiber is an abbreviation for optical waveguide fiber, mainly consisting of three layers: the inner core, the cladding surrounding the core, and the coating layer. During data transmission, the data signal primarily flows between the core and the cladding layers. The role of the coating layer is to protect the cladding and core, allowing normal signal transmission. In optical fibers, the core is primarily a transparent soft wire, the cladding is similar to the core but slightly lower in transmission efficiency, and the coating layer protects the cladding and core from external corrosion and mechanical damage.

Ⅳ.Main Development and Application Analysis of Fiber Optic Communication Technology

Due to the outstanding advantages of fiber optic communication technology, it has gradually replaced traditional cable transmission and become a new data communication technology, achieving positive development achievements and promoting the overall development of data communication technology. Furthermore, in terms of application areas, fiber optic communication has been widely applied in data communication, including network information transmission, telephone information transmission, military information transmission, and more. The specific applications are as follows:

• Application of fiber optic communication technology in network information transmission. Since network information transmission has high requirements for data transmission quality and accuracy, the advantages of fiber optic communication technology perfectly match the actual needs of network information transmission. Therefore, fiber optic communication technology has become an important method for network information transmission.
• Application of fiber optic communication technology in telephone information transmission. Currently, the telephone information transmission system has shifted from analog signals to digital signals. In this process, a reliable method is needed to ensure the reliable transmission of telephone data signals, and fiber optic communication technology happens to meet this practical need for telephone information transmission.
• Application of fiber optic communication technology in military information transmission. The key points of military information transmission are information confidentiality and accuracy. Since fiber optic communication can effectively ensure information accuracy during data transmission and is not affected by external interference, fiber optic communication technology has found important applications in military information transmission.
