As we now talk about CISCO networks, it would be very important to talk about network cables and cabling standards.
The first question may be which type of cable is used in IT networks. The answer is quite simple if we know the answer. These are some of the few answers. We will discuss only a few of the cables because IT networks use a range of cables. We will only mention some of the basic cables that are used.
1. First, we need to know which type of cable is used in IT networks. Well, the cable most commonly used in IT networks is called Category 5 cable.
Let's take a look at the history of the category 5 cable.
Category 5 cable (Cat. 5) is a twisted pair cable used to transmit signals. This type of cable is used in structured cables for computer networks such as Ethernet. It is also used to transmit other signals such as telephony and video. The cable is usually connected by drilling blocks and modular connectors. Most Category 5 cables are not protected and are based on a twisted-pair design and differential signals for noise reduction. Category 5 has been replaced by the category 5e specification.
I think Category 5e is used more often today. Typically, this is a Category 5e Cat 5e UTP cable or unshielded twisted pair cable supplied with a pair of 8 wires in different colors.
2. What is the wiring and wiring standard used for this cable type?
Typically, the T568B cabling standard is used for cabling local and small home networks-- Learn More.
Let's take a look at the basics and history of the T568B cabling standard, as mentioned below.
TIA / EIA-568 is a set of three telecommunication standards of the Telecommunications Industry Association, an EIA branch in 1988. The standards cover the wiring of commercial buildings for telecommunications products and services. The three standards bear the official titles ANSI / TIA / EIA-568-B.1-2001, -B.2-2001 and -B.3-2001.
The TIA / EIA-568-B standards were first published in 2001. They replace the now outdated TIA / EIA-568-A standards. They themselves were replaced by TIA / EIA-568-C. [A]
Perhaps the best-known features of TIA / EIA-568-B.1-2001 are the pin/pair assignment for symmetrical twisted pair wiring of eight 100 ohm conductors. These assignments are called T568A and T568B and are often (erroneously) referred to as TIA / EIA-568A and TIA / EIA-568B.
Or in simple terms.
The T568A cabling configuration ( Visit Here) is often used to connect two computers directly between them without a device.
Thirdly, we need a plug to connect our PC to the cables used in the network. Otherwise, the two media can not communicate, let alone connect.
We need a modular plug to connect the cable to PCs. Put it this way: we have a cable, then we have a computer, right?
We need to connect the cable to the computer and therefore need a modular plug. We will examine this device below.
A modular connector is a name given to a family of electrical connectors that were originally used for telephone wiring and are now used for many other purposes. Many applications that originally used bulkier and bulkier connectors have now switched to modular connectors. Perhaps the best-known applications for modular connectors are telephone and Ethernet connectors, which are almost always modular connectors.
The modular connectors were originally used with the registered connector system, which describes exactly how the connectors for telecommunications are connected. Registered connector specifications define the wiring patterns of the connectors, not the physical dimensions or geometry of the connectors of a gender. The latter aspects are instead covered by ISO 8877, which is being used for the first time in ISDN systems. TIA / EIA-568 is a standard for wired data circuits in modular connectors.
The modular connectors were originally patented in 1975 by Bell Telephone Laboratories. They replaced around 1976 cable connections on most Western Electric telephones. At the same time, they began to replace screw terminals and telephone plugs with more than 3 and 4 pins in buildings
