Today is the wireless generation. Everything is on the verge of becoming wireless; phones, TVs, computers, and many more. Soon the next generation wouldn’t know what are cables and wires. Their world is condensing itself to fit their palms.
But until that complete wireless stage is reached wires and cables are essential parts of the IT sector. Scondar Cables have been used since in the IT industry since the inception of the computers to connect computer to another computer, to transfer data and very recently connecting the laptops to other gadgets.
Though gadgets are getting wireless, IT sector still has high demand for cables to set up the servers connect and physically transferring data from one computer to another one or certain time to multiple gadgets at once and also to operate certain machinery important for a particular sector.
It is very important to know the varieties of cables that are useful in the IT industry. We have, thereby, listed the 3 most commonly used cables in the IT industry.
Fibre optics cables
Fibre optics cables are also known as Optical fibre cables and are highly used in the IT sector to provide high speed data connectivity within a building or an office with large number of computer units. These cables contain one or many optical fibres that carry light. The elements of the fibre optics are individually coated using plastic and then cased in a protective layer to suit the environment where it will be used. Generally two materials are used in the fibre optics and they are glass and plastic. The material is used depending upon the usage of the cable, plastic for short distance communication and glass for medium or long distance communication.
Fibre optics cables are quite strong and durable. Though made of glass these cables are highly flexible and bendable. They are mostly useful in wide area network (WAN) installations which employs long distance, underground or outdoor cable connection and as wire to wire connector.
There are two types of fibre optic cables in the industry standards. They are – single-mode (100BaseBX standard) and multimode (100BaseSX standard). Long-distance telecommunications networks commonly use single-mode for its relatively higher bandwidth capacity, whereas the local networks use multimode due to its cost efficiency.
Universal Serial Bus cables are generally used to connect a computer to other devices externally. They are the most commonly used cables that connect a computer to the keyboard or the mouse. There are specially made USB Cables called dongles that are used to connect the Ethernet networks to the USB ports. These cables are usually temporarily used until more permanent connecting cables are installed.
3. Twisted Pair Cables
These cables are called so as they contain pairs of wires twisted together and are the most widely used cable for the Ethernet connections. Twisting the wires together prevent interference from other close by wire pairs or other external forces.
Twisted pair cables are classified into two parts; one is Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP). STP has an extra added layer of protection to make them even better resistant to external interferences, and, hence, has an improved ability to maximize the bandwidth.
The drawback to this is that they are far heavier and cost more, which is why their primary use is within high-end applications where prevention of interference is a top priority.
The second classification has to do with categories that are separated from one another on the basis of data transfer per second. The categories in standard use are Category 5e (1 Gbps) and Category 6 (10 Gbps), as the older categories have become outdated due to performance standards that do not meet the modern-day demands of the IT industry.
