Summarize the standards for photoelectric composite cables

　　The standards for optoelectronic composite cables cover multiple aspects to ensure their reliability and performance in various application scenarios. The following is a detailed summary of optoelectronic composite cable standards:

　　First, fiber optic standards

　　Low loss: Fiber optics should have low loss characteristics to ensure that signal attenuation is minimized during tranSMission. Low loss optical fibers can maintain high-quality transmission of optical signals, thus meeting the needs of long-distance communication and high-speed data transmission.

　　High bandwidth: Bandwidth reflects the data transmission capacity of optical fiber to transmit signals. High-bandwidth optical fibers can support higher data transmission rates and greater capacity, making them suitable for high-speed data transmission in modern communication networks.

　　Low dispersion and low nonlinearity: Dispersion and nonlinearity are problems that may be encountered in optical fiber transmission, which can lead to signal distortion and performance degradation. Therefore, optical fibers in optoelectronic composite cables should have low dispersion and low nonlinearity characteristics to ensure signal stability and accuracy.

　　Environmental adaptability: Optical fibers should adapt to various environmental conditions, such as temperature changes, mechanical stress, and chemical corrosion. Excellent environmental adaptability ensures that optical fibers can work stably in various application scenarios.

　　Second, cable structure standards

　　Mechanical strength: The cable should have good mechanical strength to resist external physical damage. This includes tensile strength, compressive performance, etc., to ensure the reliability and stability of the cable during installation and construction.

　　Corrosion resistance: The outer sheath material of the cable needs to have sufficient toughness and wear resistance to resist chemical corrosion and harsh environment. At the same time, the filling and isolation layer inside the cable should also comply with relevant standards to ensure the overall stability and reliability of the cable.

　　Waterproof, fireproof or explosion-proof characteristics: Depending on the application scenario, the cable may also need to have characteristics such as waterproof, fireproof or explosion-proof. These characteristics ensure that the cable can still work stably in a specific environment and ensure the continuity of communication and power transmission.

　　III. Transmission performance standards

　　Signal transmission performance: The cable should have good signal transmission performance, including transmission speed, signal attenuation and signal distortion. Excellent signal transmission performance can ensure the stability and accuracy of optical and electrical signals during transmission.

　　Anti-interference ability: The photoelectric composite cable should have strong anti-interference ability to resist electromagnetic interference and noise interference from the external environment. This helps to ensure the clarity and integrity of the signal and improve the quality of communication.

　　IV. Labeling and documentation standards

　　Product identification: The photoelectric composite cable should be clearly marked with the product name, model, specification and production date on the outer packaging. This information helps users choose and use cable products correctly.

　　Product manual and quality certificate: It is necessary to attach a detailed product manual and quality certificate. These documents not only provide the use method and precautions of the product, but also provide effective traceability and rights protection in case of problems.

　　V. Other standards

　　In the production and testing of optoelectronic composite cables, a series of standards and specifications need to be followed, such as GB/T 9254-2008 "Communication optical cable" and YD/T 901-2018 "fiber optic cable Terms and Definitions", etc. These standards and specifications provide clear guidance and basis for the production, testing and performance evaluation of optoelectronic composite cables.

　　To sum up, the standards for optoelectronic composite cables cover fiber quality, cable structure, transmission performance, marking and documentation, and other related aspects. The formulation and implementation of these standards is of great significance to ensure product quality and promote the development of the industry.
