Chongqing, a bustling metropolis in southwestern China, is home to some of the country's most advanced communication infrastructure. As the demand for high-speed internet and telecommunication services continues to grow, it is essential to have a comprehensive understanding of the parameters that determine the effectiveness and performance of Chongqing's communication电缆. This article aims to provide you with a complete list of Chongqing communication cable parameters, along with their definitions, units, and recommended practices.
Communication Cable Types and Standards
Before delving into the specific parameters of Chongqing communication cables, it is crucial to understand the different types and standards that are used in this region. The following are the most common types and standards:
1. Fiber Optic Cables
2、Coaxial Cables (同轴电缆)
3、Wireless Communication Cables (无线通信电缆)
4、Underground Cables (地下电缆)
5、Power Cables (电源电缆)
6、Control Cables (控制电缆)
7、Optical Fiber Cables (光纤电缆)
8、Hybrid Cables (混合电缆)
9、Specialized Cables (专用电缆)
Each type of cable has its unique set of parameters that affect its performance, durability, and compatibility with other components in the communication system. Therefore, it is essential to choose the appropriate type based on the specific requirements of your project.
Parameters of Fiber Optic Cables
Fiber optic cables are widely used in Chongqing due to their high bandwidth, low latency, and resistance to interference. Here are some key parameters for fiber optic cables:
1. Number of Cores: The number of fibers in a single cable, which determines its bandwidth and signal strength. Common values range from 4 to 128 cores.
2. Core Diameter: The diameter of the fiber core, measured in micrometers (μm). Larger core diameters result in higher bandwidth but lower insertion loss.
3. Wavelength: The frequency range of light transmitted through the fiber, typically specified in nanometers (nm). Common values include 850 nm (多模光纤), 1310 nm (单模光纤).
4. Connector Type: The type of connector used to attach fiber optic cables to equipment or structures. Common connectors include ST, SC, LC, MTP/MPO, and COPTER.
5. Operation Temperature: The maximum operating temperature of the fiber optic cable, measured in degrees Celsius (°C). Higher temperatures can cause damage to the optical properties of the fiber.
6. Age Limit: The maximum age of the fiber optic cable without compromising its performance. Older cables may exhibit increased attenuation and signal loss over time.
Parameters of Coaxial Cables
Coaxial cables are commonly used for cable television, satellite communication, and telephone systems in Chongqing. Here are some key parameters:
1. Wavelength: The frequency range of electromagnetic radiation transmitted through the coaxial cord, typically specified in赫兹 (Hz). Common values include VHF (超高频), UHF (超低频), and SHF (特高频).
2. Shielding: The presence of shielding around the coaxial cable to prevent external interference and improve immunity to electromagnetic pulses (EMPs). Common types include twisted pair shielding, aluminum foil shielded, polyethylene braided shielded, and multi-layer braided shielded.
3. Insulation: The material used to insulate the coaxial cable against electrical discharge and moisture intrusion. Common materials include PVC, XLPE (交联聚乙烯), and Teflon-impregnated fiberglass insulation.
4. Conductor Material: The material used for the inner conductor of the coaxial cable, typically copper or aluminum alloys such as galvanized copper or aluminum-clad steel.
5. Diameter: The thickness of the outer insulation layer around the conductor, measured in inches (inches) or millimeters (mm). A thicker insulation reduces signal loss but increases weight and cost.
