This tutorial explains the types of network cables used in computer networks in detail. Learn the specifications, standards, and features of the coaxial cable, twisted-pair cable, and the fiber-optical cable. To connect two or more computers or networking devices in a network, network cables are used. There are three types of network cables; coaxial, twisted-pair, and fiber-optic. This cable contains a conductor, insulator, braiding, and sheath.

Network Cable Types and Specifications

UTP is by far the most used networking cable. It typically consists of 4 pairs of 2 wires 8 separate wires total , all within one casing. Each pair of two individual wires are twisted around each other to cancel out EMI electromagnetic interference. The standard connector in computer networking is an RJ There are four colors associated with the eight wires within the cable.

The colors of the wires determine where they will be terminated in the RJ45 connector. The color code is Blue , Orange , Green , and Brown. In other words, there are two blue wires — One is mostly blue with white stripes, the other is mostly white with blue stripes.

These cable types are determined by where the various colored wires are terminated installed within the RJ45 connector. In a straight cable also called a straight through cable, the wires are terminated on the same RJ45 pins at both sides of the cable:. Although not all wires are in use, they should be terminated identically to what is show in the graphic.

For example, a straight cable is used to connect a switch L2 to a router L3. In a crossover cable, four wires are reversed or crossed. Pins 1,2,3,6 on the left are terminated on 3,6,1,2 on the right respectively:.

For example, a crossover cable is used to connect a router to another router. Don't spend too much time studying all of the pin outs, speeds, or distances. Here is quick reference that should help your study; this is all that must be memorized:.

When enabled, you will not need to use a crossover cable for switch-to-switch connections. The "crossover" is done through software. However, this technology should not be considered unless you are specifically told the switch supports it.

For example, if our practice question asks you what type of cable should be used for a switch-to-switch connection, the answer is crossover. Fiber Optic cable uses light to send signals from one device to another. This is different than copper cabling that uses electric signals. Thus, fiber optic cables are not affected by EMI and can often achieve much greater distances without signal loss.

The RJ45 connector works with twisted pair cabling and is the most common type of connector in modern networks. In addition, the RJ45 connector is used on Cisco console cables. You don't necessarily have to memorize the names of each Fiber Connector. However, you should be able to identify all of these as belonging to the Fiber family. The 60 in DB60 indicates the connector has 60 pins. These connectors are typically used with Serial WAN connections.

Three Major Types Of Network Cables Used In Communication Systems

Certify and Increase Opportunity. Be Govt. Certified IT Support Professional. This type cable is usually yellow in color and used in what is called thicknets, and has two conductors. This coax can be used in meter lengths. The cable itself is made up of a solid center wire with a braided metal shield and plastic sheathing protecting the rest of the wire.

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network. The following sections discuss the types of cables used in networks and other related topics. Twisted pair cabling comes in two varieties: shielded and unshielded.

Network Cabling and Connectors

Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers , scanners etc. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's physical layer , topology , and size. The devices can be separated by a few meters e.

UTP is by far the most used networking cable. It typically consists of 4 pairs of 2 wires 8 separate wires total , all within one casing. Each pair of two individual wires are twisted around each other to cancel out EMI electromagnetic interference.

This tutorial explains network cable connector types and specifications in details. It is expected to replace serial and parallel ports. A single USB port can be used to connect up to peripheral devices, such as mice, modems, keyboards, digital camera's, printers, scanners, MP3 players and many more. USB also supports Plug-and-Play installation and hot plugging. USB 2. USB has with two connector types. The Type B on the left connector and is for connecting to the relevant peripheral.

Whatever type of network is used, some type of network medium is needed to carry signals between computers. Two types of media are used in networks: cable-.


LAN Network Cable Media and Connectors

Collection and Use of Information

Fiber optic cable, twisted pair cable, and coaxial cable are the three main types of network cables used in communication systems. Each of them is different and suitable for various applications. Fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. Fiber Optic cable has a complicated design and structure. This type of cable has an outer optical casing that surrounds the light and traps it within a central core. The inside of the cable the core must configured in two different ways — Single-mode and multi-mode; although the difference may seem small, it makes a tremendous difference to the performance and the usage of fiber optic cables. Twisted pair cable is a type of ordinary wiring which connects home and many business computers to the telephone company.

A common entry position is user support; this position requires that the individual have at least decent personal skills and at a minimum, a working knowledge of the systems the users utilize. These systems often include an operating system, a workstation, and a LAN connection to internal networking resources. This article takes a look at the LAN network cable media that is typically installed in most environments and the different connectors that are often used.

GOV Гнев захлестнул ее, но она сдержалась и спокойно стерла сообщение. - Очень умно, Грег. - Там подают отличный карпаччо.

 Цепная мутация, сэр. Я проделал анализ и получил именно такой результат - цепную мутацию. Теперь Сьюзан поняла, почему сотрудник систем безопасности так взволнован. Цепная мутация. Она знала, что цепная мутация представляет собой последовательность программирования, которая сложнейшим образом искажает данные.

Я требую выпустить меня отсюда. В ответ - тишина. Его руки крепче сжали ее шею.

Оказавшись в условиях подлинного разведывательного затемнения, АНБ выпустило секретную директиву, одобренную президентом Соединенных Штатов. Заручившись поддержкой федеральных фондов и получив карт-бланш на все необходимые меры для решения проблемы, АНБ приступило к созданию невозможного - первой универсальной машины для вскрытия шифров. Вопреки широко распространенному мнению о том, что такой компьютер создать невозможно, АНБ осталось верным своему девизу: возможно все; на невозможное просто требуется больше времени.

Все подняли головы. - Три! - крикнула Сьюзан, перекрывая оглушающую какофонию сирен и чьих-то голосов. Она показала на экран.

    Coaxial cable. • Success in both TV transmission and network implementations. • Insulation, ground, insulation, main wire. • Networks use two types of coaxial.
