Introduction
Communications have always been an essential aspect of human life. With the advent of technology, communication devices have become more advanced and sophisticated, allowing people to connect with each other from different parts of the world in real-time. One of the critical components that facilitate this communication is the cable used to transmit data between devices. In this review, we will focus on the encapsulation cables used in telecommunications, specifically the 10 most commonly used pairs.
Section 1: Introduction to Encapsulated Cables
Encapsulated cables are a type of cable that uses an outer protective layer to enclose the inner conductor(s). This protective layer helps to prevent interference from external signals, ensuring that the transmitted signals remain clear and accurate. Encapsulated cables are used in various applications, including telecommunications, computer networking, and electrical power transmission. The following sections will provide a comprehensive overview of the 10 most commonly used encapsulation cables in communications.
Section 2: Types of Encapsulated Cables
There are several types of encapsulated cables available in the market, each designed for specific applications. Some of the common types include:
1、Twisted-Pair Cables: These cables consist of two or four twisted wires inside an outer insulation material. They are widely used in telephone lines and Ethernet networks.
2、Coaxial Cables: Coaxial cables consist of a central copper wire surrounded by a polyethylene 绝缘层 and a plastic sheath. They are commonly used for cable television and satellite communications.
3、Fiber Optic Cables: Fiber optic cables use light waves to transmit data instead of electrical signals. They are highly efficient and can transmit data over long distances without any loss of quality.
4、Power Cables: Power cables are designed to carry electrical power from one point to another. They are typically made of thick insulation materials to protect the conductor(s) from damage due to high voltage levels.
5、Radio Frequency (RF) Cables: RF cables are used for transmitting signals over short distances, such as within buildings or between two close points in the same building. They are often used in wireless communications technologies like Wi-Fi and cellular networks.
6、Infrared (IR) Cables: IR cables use infrared light to transmit signals over short distances. They are commonly used in remote control systems and home automation devices.
7、Low-Voltage AC Cables: These cables are designed for low-voltage AC power transmission and distribution. They are typically made of PVC or rubber insulation materials and have a flexible core.
8、High-Voltage AC Cables: High-voltage AC cables are used for power transmission over long distances, such as electricity grid connections or industrial processes. They are typically made of XLPE or PE insulation materials and have a solid core.
9、Ultrahigh Voltage (UHV) AC Cables: UHV AC cables are designed for ultra-high voltage power transmission over long distances. They are typically made of kevlar or other strong materials and have a semi-rigid or rigid core.
10、Ultrahigh Voltage (UHV) DC Cables: UHV DC cables are used for ultra-high voltage direct current (DC) power transmission over long distances. They are typically made of kevlar or other strong materials and have a semi-rigid or rigid core.
Section 3: Characteristics of Commonly Used Encapsulated Cables
Each type of encapsulated cable has unique characteristics that make it suitable for specific applications. The following sections will discuss the characteristics of some of the most commonly used encapsulated cables in communications:
1、Twisted-Pair Cables: Twisted-pair cables are generally inexpensive and easy to install, making them popular for household wiring and small business networking needs. However, they have lower bandwidth capacities than other types of cables and can be easily damaged if not handled properly during installation.
2、Coaxial Cables: Coaxial cables have higher bandwidth capabilities than twisted-pair cables but are more expensive to install. They are also less flexible than twisted-pair cables, which can make them challenging to work with in tight spaces. Coaxial cables require proper shielding to avoid interference from external sources, which can increase their cost further.
3、Fiber Optic Cables: Fiber optic cables offer high bandwidth capabilities, low latency, and immunity to electromagnetic interference (EMI). They are also highly flexible and can be easily installed in complex environments. However, fiber optic cables are more expensive than other types of cables and require specialized equipment to install and maintain.
Section 4: Applications of Commonly Used Encapsulated Cables
The applications of encapsulated cables vary depending on their type and characteristics. The following sections will discuss some of the most common applications for each type of encapsulated cable:
1、Twisted-Pair Cables: Twisted-pair cables are commonly used for local area networks (LANs), telephony systems, and video surveillance systems. They are also used in data centers for connecting servers and storage devices.
2、Coaxial Cables: Coaxial cables are commonly used for cable television, satellite communications, and wireless networking applications likeWi-Fiandcellular networks
