The Network cable is simply a cable used to network the devices, i.e. they are used to connect and transfer data among various devices such as computers, switches, routers, etc. These cables can be used to plug computers into modems, access points or grounded ports. These cables are also used to share peripheral devices such as printers, scanners or projectors among various computers. Depending upon the speed, size, and topology of the network structure, there are different types of cables available in the market. The most common of them are twisted pair cables, coaxial cables, and fiber optic cables. So it is important to know about these cable types before you buy it.
Here we are discussing some of the Network cables that are available:
Twisted Pair Network cables:
These are the oldest Networking cable types and was once regarded the leading cabling standard for Ethernet. They comprise of thin copper wires that are twisted (to prevent interference) and are packed inside an insulated sheath. Commonly there are two twisted pair cable types: UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair). The supported speed can range from 10 Mbps (10Base-T or Cat3) to 10 Gbps (10GBase-T or Car5e). The design of these types of cables increases the reliability and minimizes network failures. Due to their lower cost, they are used in modern Ethernet equipment. The STP cables are used in modern high-speed connections like FDDI (Fiber Distributed data Interface).
Coaxial Network Cables:
In their onset, these cables were used to connect television sets to home antennas. As the time flows, these cables become a standard for 10 Mbps Ethernet cables due to their noise reduction capabilities. Typically there are two types of Coaxial cables: Thinnet (10Base2, i.e. 10 Mbps up to 200 Meter) and Thicknet (10Base5, i.e. 10 Mbps up to 500 Meter). These cables are comprised of inner copper wire of varying thickness, protected by a PVC insulation coating. The design of the cable provides protection to the data signal from external electromagnetic interference, hence reduces the power loss in transmission. A good coaxial table can be used to transmit any kind of signals such as HDTV, videos, FM, and much more.
Fiber Optics Network Cable:
Fiber optic cables are special networking cables that carry signals in form of light and use glass strands as signal carrying medium. These are high-speed network cables generally used in WAN (Wide Area Network) where long distance communication is needed. They are also used in high communication traffic volume areas such as office buildings, universities and large data centers. There are mainly two types of Fiber optic cables: Single-mode (100BaseBx) and multi-mode (100baseSx). Due to higher bandwidth capacity, single-mode cables are used in long distance telecommunications, whereas due to lower cost multi-mode cables are used in local networks.
Other Network Cables:
Other network cables like crossover cables are used to connect the same type of network devices such as two computers or two network switches. The Patch cables are short length cables, used in the straight-through network for temporary purposes. USB cable is also a kind of network cables used to connect a computer with peripheral devices.
Although the modern era of communication tends to use wireless technology, but it is important to understand that the individual computers may connect to servers wirelessly and those servers are still grounded. We still require wired medium to connect devices with modems or any other internet source. So these networking cables are still an important part of telecommunication systems.
