Chapter 1: Introduction to Fixed Cables in Communication Engineering
1、1 Definition of Fixed Cables
Fixed cables are linear conductors used in communication systems to transmit signals over long distances. They are typically made of copper or aluminum wires insulated with plastic or rubber material.
1、2 Types of Fixed Cables
There are several types of fixed cables used in communication engineering, each designed for specific applications and operating conditions. The following sections discuss the major categories of fixed cables:
Chapter 2: Coaxial Cables (同轴电缆)
2、1 Definition of Coaxial Cables
Coaxial cables are two concentric wires enclosed in a plastic or metal sheath, separated by a thin layer of dielectric material. They are commonly used in cable television, radio, and telecommunications systems.
2、2 Characteristics of Coaxial Cables
Coaxial cables have excellent noise immunity, low loss, and high bandwidth. They are also relatively immune to electromagnetic interference (EMI) and radio frequency interference (RFI). However, they require precise alignment and shielding to ensure proper signal transmission.
2、3 Applications of Coaxial Cables
Coaxial cables are widely used in cable television systems, including CATV, DBS, and DVB-S/T. They are also used in satellite communications, wireless local area networks (WLANs), and power line communications.
Chapter 3: Fiber Optic Cables (光纤电缆)
3、1 Definition of Fiber Optic Cables
Fiber optic cables are made from glass or silicon fibers surrounded by a cladding material, which helps to prevent light scattering and enhance signal clarity. They use light rather than electrical voltage to transmit data signals.
3、2 Characteristics of Fiber Optic Cables
Fiber optic cables have extremely low loss, high bandwidth, and excellent reliability. They can transmit data over long distances without degradation due to signal attenuation. However, they require sophisticated hardware and installation procedures to ensure optimal performance.
3、3 Applications of Fiber Optic Cables
Fiber optic cables are primarily used in high-speed broadband internet connections, including fiber-to-the-home (FTTH) and fiber-to-the-office (FTTO) systems. They are also used in telecommunication networks, data centers, and scientific research facilities.
Chapter 4: Twisted Pair Cables (双绞线)
4、1 Definition of Twisted Pair Cables
Twisted pair cables consist of two twisted pairs of copper wires insulated with a protective coating. They are commonly used in local area networks (LANs) and computer networks.
4、2 Characteristics of Twisted Pair Cables
Twisted pair cables have lower bandwidth compared to other types of cables but are relatively inexpensive and easy to install. They are also highly flexible and can be easily routed through walls and other obstacles. However, they require precise alignment and shielding to avoid crosstalk and interference.
4、3 Applications of Twisted Pair Cables
Twisted pair cables are widely used in LAN installations, including home networks and small office/home office (SOHO) setups. They are also used in telecommunication systems, such as telephone lines and modem connections.
Chapter 5: UTP Cables (通用用户终端电缆) and STP Cables (屏蔽用户终端电缆)
5、1 Definition of UTP Cables and STP Cables
UTP cables are unshielded twisted pair cables, while STP cables have additional shielding around the twisted pairs to reduce interference from external sources. Both types of cables are commonly used in LAN installations and computer networks.
