LEARN MORE ABOUT THE MAGIC OF CABLES AND GET MESMERISED‼!

The invention of the fiber optic cables is a boon in the world of science and technology. Fiber optic cable is made of pure silica (glass). It is flexible and transparent in nature and its thickness is not more than the thickness of human hair. It transmits light between the two ends of a fiber and works like a ‘light pipe’. Fiber optic cables are used widely in the field of communication. As fiber optic cables are flexible and can be assembled in bundles, they can be used as a medium for telecommunication and computer networking. Fiber optic cables carry light impulses and they are quiet expensive. But it can’t be denied that it have a higher bandwidth. In fiber optic cables, light propagate through fiber with scanty attenuation, so it is a convenient option for long distance communication. Fiber optic cables, if used for short distance application, it saves space in cable ducts. In the sphere of remote sensing, fiber optic cables offer many usages. In many cases, we find the fiber optical cable itself acting as a censor. In fiber optic cables, there is no need of any electrical power at the location of the remote. One of its advantages is its small size which can be cashed in many applications. Strain, temperature and pressure and many other quantities can be measured by fiber optic cables if used as sensors. Optical time domain reflector is an instrument made by fiber optic cables which is used to determine the time delay. Advance intrusion detection system makes the use of fiber optic cables as sensor. For fulfilling our illumination needs, we make use of fiber optic cables widely. They are used as light guides in medical and many other applications.

Network cables are also found to be used widely in the present times. Network cables establishes the connection between one network devices to another. This is needed to connect two or more computers to facilitate the sharing of devices like printers, scanners and many more. Depending on network’s topology, protocol and size network cables can be broadly divided into three categories namely Coaxial Cable, Optical fiber cable and twisted pair. Wireless network cables rule the times now. These days networks work with wireless network mode. High frequency radio signals, infra red beams, lasers are used by the wireless LANs to connect the work station, servers, hubs etc. Wireless networks work wonders as it allows the laptops, computers, portable devices etc to get connected with the LAN. While you are installing a network cable, you must always use more cable than you actually need. Plenty of slacks must be left behind. Every part of the network needs to be examined properly as you install it. Even if the cable is brand new, you should not take any chances as it might lead you to some mess, and afterwards it will be difficult to isolate it. A minimum distance of 3 feet must be maintained from the fluorescent light boxes and sources of other electrical interferences as it might be dangerous. Both the ends of the cable should be taped properly and cable ties must be used. With the invention of fiber optic cables and wireless cables, the use of network cables is facing a downward graph.

HOW FRUITFUL THE EFFECTIVE NETWORK SUPPLIES ARE?

Network supplies are a process that is carried out at both the facility nodes and distribution links. It is a value addition process for the customers through manufacturing and delivery goods. One of the instances of a network supplies is supply chain. Resilient network supply is a form of network supplies where the strategies, operations, structure of governance etc are well designed to ensure they can handle the frequently changing market policies and market risks. Strong determination, speed and precision are the key words for resilient network supply. As per the change of circumstance, network supplies must reinvent new business models. Network supplies are one of the most important factors that ensure flawless service to the customers and ensure their satisfaction.

A shielded cable is a type of electric cable which consists of insulated conductors enclosed by a common conductive layer. Shielded cables are also known as screened cables. The shield can be made up of copper, aluminium, copper tape, a layer of conducting polymer. Usually, a jacket covers up this shield. The shield reduces the electronic noise so that it does not affect the signals. It also reduces electromagnetic radiation that can interrupt other devices. Shielded cables are used for security purposes. Shielded cables are used in security systems to provide protection from power frequency and radio frequency interruptions to reduce the number of false alarms. It is the best to maintain a distance of at least 3 inches between signal cables and heavy power circuits which run parallel. They are also used in recording studios. In shielded cables we find the shield acting as the return path for the signal. It may only act as screening also. Shielded cable carries data faster than non-shielded cable. It is true fact that shielded cables are more expensive on the pockets. Shielded cables ensure quality transmission. Quality transmission is done by reducing the cross talks that occurs within network transmission. The braided shield ensures the transmission does not stop and it goes through. Shielded cables are generally used as conductors and neighboring cables. Shielded cables ensure that the loss of transmission does not take place. This is an advantage of using shielded cables. Shielded cables are also known as screened cable. Shielded cables are broadly divided into three categories:

Fiber optical cables- A number of optical fibers make a fiber optic cables. The fibers have plastic coatings in many layers. These coatings provide strength to the fiber. But the plastic coatings play no part in functioning of the wave. These cables are used predominantly in fiber optic communications. Fiber optical cables ensure long distance communication. Illumination purposes use fiber optical cables.
Link
Building Wire- This form of shielded cable is industrial. It is used for industrial, commercial and residential purposes. It is also known as branch circuit wiring. It is used for power distribution and branch circuits.

Coaxial Cables- This form of shielded cable is electricLinkal. Radio frequency signals are transmitted by using coaxial cables. Lower frequency is conducted by coaxial cables.
