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.
