Network Cable Types and Specifications
Before we dicuss Networking cables, let us know What actually Networking is? The network is the interconnection of the different systems and devices. In our daily life, we consist of a bunch of devices like desktop systems, mobile devices, laptops, Ipads, etc. All these are interconnected to each other to share, receive, and retrieve the information from the devices. We can send work to a printer, print the copy, send a streaming video to the other system user and we can also use it to share the internet connection.
To communicate with all these devices, we need a connector to connect between the devices is called a cable. Since we are using it to connect the networks we call it the networking cable. The Networking cables are used to connect the multiple devices to each device and a single central device. The central device is called the switch. The Best example of a Networking cable is a computer lab. In the Computer lab, we connect multiple computers to a single central device called switch using the networking cables.
In some cases, the computers are connected to a wall socket and this wall socket is again connect through another cable to a cabinet or a panel. These cabinets or panel then again connects to a switch. All the devices can connect directly to the switch. For the Wired connection, we connect through the different cables like twisted pairs, coaxial cables, Ethernet cables, fiber optic cables, etc. There are many more cables for the wired connection.
Whereas in the wireless connection, it exists after the wired connection. Mobile devices, radios use wireless connections. Normally, the very known best example of a Wireless connection is Wi-Fi. Networking cables can be of different types of copper cables, fiber cables. The copper cables are cheaper than fiber cables.
And these copper cables are mostly used for short-range communications. Coming to the fiber optic cables, it is the set of strands of glasses. The data we can send through the fiber in the form of light signals.
Fiber optic cables are more expensive than copper networking cables. It is mostly used for longer-distance communications since it is highly expensive.
The networking cables use an ethernet protocol. We have known protocol consists of a set of rules. The Ethernet cables are made of many different parts. In the physical layer, it describes the different cablings with their speed. In the medium access layer, it describes how the data get transmitted and formatted. The main aim of the ethernet cables is, we can communicate even on different cables and at different speeds.
Suppose User A has a network speed of one-gigabit connection wants to send a message to User B. The message is first moved into the media access control to prepare the message format according to the media access control rules and follows the physical rules to send the message to another network device.
After the message is received at the other end, it decodes the message at the physical layer and sends it to the receiver device. Even in the different connection speeds, we can deliver the information on the receiver side of the network. The standard used for the Ethernet LAN is The Twisted pair cable is one type of Ethernet cable. These are used for connection in the local area networks. The Twisted pair cables are connected to the local router or a modem so that we can provide internet access to the local devices.
One end of the Twisted pair cable consists of the interface card and the other end plugs are connected to a router sitch or a modem. The Unshielded twisted pairs are the most common type of cables.
It consists of four different color code wires that are twisted into pairs. Now, why do these colors are getting twisted? To prevent Electromagnetic interference and crosstalk, the Unshielded twisted pairs are get twisted in pairs.
The Twisted pair cables are mostly used in homes and for many business purposes. It is similar to the shielded twisted pairs, the main difference between the two is a foil shield is wrapped around the color-coded pairs alike from the Unshielded twisted pairs. It has an extra layer of protection to prevent electromagnetic Interference.
It is mostly used in Industries. For the Twisted pair cables, simply we have to connect the RJ45 connectors at both ends of the Twisted pairs. All the specifications of the networking cables are present at the physical layer of the OSI model. The Below figure represents the coaxial cable. It consists of a sheath at the outer cover layer. This sheath is a fire-resistant plastic. To reduce the electromagnetic interference the sheath is established at the outer covers of the coaxial cable.
Under sheath, it consists of a Teflon insulator and a copper conductor is present at the center of the coaxial cable. The coaxial cables are used to transmit high-frequency signals with fewer data losses. The Coaxial cables are mostly used in telephone systems, cable TVs, and broadband connection. RG stands for the Radio guide. Each number uses different data cables. There are also many types of connectors in the coaxial cable.
BNC and F-type connectors are also called the end type connectors. It can carry the information in the form of microwave signals. SMA stands for the Subminiature version. It uses higher frequency microwave systems and Wi-Fi systems. F-type connectors are mainly used in local connections like cable TV and cable Internet connection. The Fibre Optic cables, simply carry the information in the form of light signals.
It offers high maintenance cost and very expensive than the copper networking cables. These Fibre Optic cables can be of two types. The below figure represent the structure of the coaxial cable. It consists of a core that surrounds several protective layers. The Outer layer we call the jacket is used to protect the inner components.
The second layer of the Fibre optic cables, we call the buffer to encapsulates one or more optical cables to protect them from physical damage. And the layer around the fiber optic core, we call it the cladding. It is made of glass or a plastic. The cladding has two main properties.
It is used to protect the core, the light bouncing and reflection allow fiber to bend around the corners without affecting the transmission of the signals. The last layer of the fiber optic cable is the central core cable, which is made of glass fiber lights, The LED can travel through the cores. The single-mode is designed to carry the signals with a single-mode. It means the light signal can travel in the same way and in the same pattern. The single-mode only provides a single ray of light.
It has a high data transfer rate event in long-distance communications. Single-mode has a very tiny diameter of 9 microns or micrometers and with a width range of a maximum of microns.
The core of the optical cable is not visible without the help of any special equipment. Mostly the single mode is widely used for long-range communications. The best example is the WAN connection. WAN stands as the wide-area network. The Multimode fiber is mostly used for short-range communications. Within the campus or school, the multifiber model is benefited.
It is different from the single mode, the light disperses in different directions and travel through the cladding core. These Multimedia links are used with a speed of gigabits per second. Straight through cable is the most common cable that we use to construct the ethernet. It maps the pins directly to the other end which means one end of the cable will match with the other end of the cable.
Similarly, different pins in cable do the same process in transmitting the data,. The cross over cables works similar to the Telephone cable. To understand the concept, let us take an example.
When we speak via mic attached to our telephone, this information is sent to the other side of the speaker using a cross over the connection. The pins in the cross over cable receives the different pins. We should be able to determine the cable connection must be used in the transmission of the data between the different device.

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. As with the thick coaxial cable is used in thicknets the thin version is used in thinnets.
Also, the most specific and common type of utp connector cable is known as an rj Common types of networking cables free download as powerpoint presentation.

Она точно окаменела. И закрыла. О Боже, пожалуйста. Не. ГЛАВА 65 Бринкерхофф мерил шагами кабинет Мидж Милкен.
Он посмотрел вверх, на крышу трехэтажного дома, развернулся и бросился назад, но почти тут же остановился. В некотором отдалении от него возникла фигура человека, приближавшегося медленно и неотвратимо. В руке его поблескивал пистолет. Беккер, отступая к стене, вновь обрел способность мыслить четко и ясно. Он почувствовал жжение в боку, дотронулся до больного места и посмотрел на руку.
Он улыбнулся. Значит, все правда. - Из какого именно места в Штатах? - спросил. - Они ищут, господин. - Очень хорошо.
