With the advancement of technology, optical fiber cables have made significant breakthroughs and improvements in materials, structure, and application fields. 1. Materials and Structure: Modern optical fiber cables are mainly composed of optical fibers, reinforcing elements, and protective sheaths. The optical fiber is the core part of the cable, responsible for the transmission of light. Its material is mainly high-purity glass or plastic with high transparency and low loss characteristics. Reinforcing elements protect the optical fiber from breaking when subjected to external forces. The protective sheath protects the entire optical fiber cable from external environmental influences. 2. Application Fields: Optical fiber cables are widely used in telecommunications, cable television, computer networks, and other fields. Their advantages of fast transmission speed, strong anti-interference ability, and good confidentiality make optical fiber cables play an increasingly important role in communication networks. Optical Modules: Optical modules are important equipment in optical communication, responsible for completing the function of electro-optical conversion. With the continuous development of network technology, optical modules have significant improvements in transmission speed, distance, and stability. 1. Working Principle: The optical module converts electrical signals into optical signals or optical signals into electrical signals through an electro-optical converter. Its core components are lasers and photodiodes. Lasers are responsible for emitting optical signals, while photodiodes are responsible for receiving optical signals and converting them into electrical signals. 2. Classification and Characteristics:

Optical modules are mainly divided into single-fiber and multi-fiber types. Single-fiber optical modules use a single fiber to complete the two-way transmission of electro-optical conversion, while multi-fiber optical modules use multiple fibers for transmission. Additionally, depending on the transmission rate and distance, optical modules are divided into various types such as Gigabit optical modules and 10 Gigabit optical modules. Moreover, with the continuous development of network technology and increasing demand, the anti-interference ability, stability, and compatibility of optical modules are also constantly improving. Their high-speed, large-capacity transmission capabilities and good compatibility make optical modules widely used in data communication, video transmission, and other fields.
