For any networking to be effective, raw stream of data is to be transported from one device to other over some medium. Various transmission media can be used for transfer of data. For example, copper wires, fibre optic wires, etc.
Explain the twisted pair cable , its types, advantages and disadvantages. Ans:Twisted pair cable: A twisted pair consists of two conductors each surrounded by an insulating material. Twisted pair cable consists of a pair of insulated wires twisted together. It is a cable type used in telecommunication for very long time. Cable twisting helps to reduce noise pickup from outside sources and crosstalk on multi-pair cables.
Fiber optic cable, twisted pair cable and coaxial cable are three major types of network cables used in communication systems. Each of them is different and suitable for different applications. Since each of them can be equally applied into network communication, how they distinct from each other in terms of features and specifications? Fiber optic cable , also called as optical fiber cable, is a type of Ethernet cable which consists of one or more optic fibers that are used to transmit data.
Fiber optic cable transmits data as pulses of light go through tiny tubes of glass. The transmission capacity of optical fiber cable is 26, times higher than that of twisted pair cable.
Figure 1: Fiber optic cable. Single mode optical fiber has a small core, and only allows one mode of light to propagate at a time. While multimode fiber cable comes with a larger core and is designed to carry multiple light rays or modes at the same time.
And the transmission distance of single mode fiber cable is up to several kilometers, while the multimode fiber is up to meters over 10G network.

Twisted pair cable is often used for telephone communications and most modern Ethernet networks. It is a kind of wiring in which two conductors of a single circuit are twisted together. A pair of wires forms a circuit that can transmit data. And the pairs are twisted together to provide protection against crosstalk, the noise generated by adjacent pairs. Figure 2: Shielded twisted pair. The STP copper cable has a foil-wrapped outside on each pair of wires.
The four pairs of wires then are wrapped in an overall metallic braid or foil, usually ohm cable. Coaxial cable, or coax cable, is designed to transmit high-frequency signals. With the shield construction, the coaxial cable can support longer cable lengths between two devices. Figure 3: Coaxial cable. There are a number of different types of coax, but only two—RG59 and RG6—get the most use in residential applications. Except for the construction differences of fiber optic cable vs twisted pair cable vs coaxial cable, these three types of cables distinguish from each other in cable performance and capacity.
Coaxial cable and twisted pair cable are copper or copper-based wire surrounded by insulation with other materials. Both of them can transmit television, telephone and data with electrical signals.
While fiber optic cable can deliver the same types of signals with much wider bandwidth, faster speed and higher frequencies. In general, fiber optic cable is more expensive than copper cable due to its high performance and capacity. However, in the cable market, the price of fiber optic cable, twisted pair cable and coaxial cable varies from different suppliers and vendors.
Before buying these cables, making a careful comparison is important. They may change with time. From the table, we can see fiber optic cable has the lowest price at the same cable length. However, the total installation of optical fiber cables also can be high because of other optical components used, especially optical transceivers. In addition, twisted pair cable with RJ45 connector cost less than coaxial cable which often comes with a BNC connector.
And fiber is fragile and thinner than twisted pair cable and coaxial cable, which make it need more cares to install, operate and maintain. Compared with twisted pair cable, coaxial cable can reach longer distance. And they are widely used in data centers where a large volume of data needs to be transmitted.
Figure 4: An fiber optic cable application. Twisted pair cables are majorly used in telephone networks, data networks and cable shielding. And they also can be used for high-definition media interface connections. In sum, there are obvious differences among fiber optic cable vs twisted pair cable vs coaxial cable. Fiber optics seem to become the trend for the increasing demand of the market as the technology develops fast.
However, whether to choose twisted pair cables, coaxial cables or fiber optic cables still depends heavily on applications, which is subject to the cost, transmission distance and performance. RG6 RG6 coaxial cable is heavier gauge and has thicker insulation and better shielding. It is better for digital video signals and satellite TV. RG59 is the basic coax cable.
RG6 coaxial cable is heavier gauge and has thicker insulation and better shielding.
Network cables are used in communication systems around the world. Using the correct cable will ensure the best performance of the network. Therefore, whether the correct cable is selected according to the requirements of the system will play a crucial role in whether the installed communication system can play an ideal use effect. Each type of cable has different uses and has specific advantages. If the wrong cable is installed, it will not reach the ideal performance level of the system. When choosing the right cable for the network to achieve the best performance, there are many factors to consider, including:. Starting from the above five aspects, this article briefly summarizes the advantages and disadvantages of the three most commonly used cables, coaxial cable , twisted pair , and fiber optic cable.
This article systematically introduces the classification of twisted pair cables and its advantages and disadvantages. At the same time.
As a VGM stands for voice grade medium , twisted pair cable is the basis for the most internal office telephone wiring. Due to differences in the electrical characteristics, problems can occur between the pair, for example, length, resistance, capacitance.
Our teams always devote ourselves to track development and application of the newest optical communication technology in the world. Modern Ethernet, the most common data networking standard, can use UTP cables. Fibers are used for imaging in reach areas, such as sensory devices to make temperature, as wiring where EMI is an issue, pressure, as wiring in industrial settings and automobiles. Matthew Maximum-technology. Good post Network Cable Repairing Services. A fiber-optic system is similar to the copper wire system that fiber-optics is replacing.
The pair of twisted is the simplest transmission medium. This type of support is suitable for transmission both analog and digital. The twisted pairs may be shielded, metal sheath surrounding completely metallic pairs or unshielded. In this case, a metal tape around the son.
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.
Сегодня утром Дэвид рассказал мне о ваших планах.
Произошло нечто непредвиденное. - Танкадо мертв. - Да, - сказал голос. - Мой человек ликвидировал его, но не получил ключ. За секунду до смерти Танкадо успел отдать его какому-то туристу.
- Что он ищет? - Мгновение он испытывал неловкость, всматриваясь в экран, а потом принял решение. Хейл достаточно понимал язык программирования Лимбо, чтобы знать, что он очень похож на языки Си и Паскаль, которые были его стихией. Убедившись еще раз, что Сьюзан и Стратмор продолжают разговаривать, Хейл начал импровизировать. Введя несколько модифицированных команд на языке Паскаль, он нажал команду ВОЗВРАТ.
Да, панк, - сказала Росио на плохом английском и тотчас снова перешла на испанский. - Mucha joyeria.
- Джабба театральным жестом указал на громадный экран. - Дамы и господа, - он опять тяжело вздохнул, - перед вами компьютерный агрессор-камикадзе… червь. - Червь? - с недоумением переспросил Бринкерхофф. Название показалось ему чересчур земным для такого агрессора.
Но. Увы, она уже знала ответ. Так вот какова месть Танкадо. Уничтожение ТРАНСТЕКСТА.
Мысли его вернулись к Кармен. Перед глазами возникло ее гибкое тело, темные загорелые бедра, приемник, который она включала на всю громкость, слушая томную карибскую музыку. Он улыбнулся.
