Basic Guide For Beginners On Fibre Optic CablingBasic Guide For Beginners On Fibre Optic Cabling

Now that we are already on the age of computers, almost all of us know that a structured fibre optic cabling is the most significant part when it comes to networking of computers. Its very essence is to be the very foundation of every business, that provides connectivity between servers and other network devices while allowing voice and text information to spread around the globe. The basic of fibre optic cabling primarily involves the use of different mediums to carry data from point A to point B and then back from its source. Just few years ago, the use of twisted pair copper cable has introduced us to global networking and since then more innovations in data cabling has been introduced.

Today, we are still using this same wiring technology because these are still reliable. But as technology improves and advances, the demand for more connectivity was sought and that is why we have came up with the new wiring technology in the form of fibre optic cabling technology. This is the more advanced form of network cabling and it is becoming the next generation standard in the world of data cabling.

Advantages of Fibre Optic Cabling

1. They can send and bring back signals quicker and with longer distances. Basically fibre optics is 50 times more powerful in exchanging signals than copper wires because copper wires have low attenuation rates. This means that with copper wires, there is the loss of signal as the data travels on long wires. Copper wires also require signal repeaters when the signals are coming from very long distances. Fibre optics eliminates these issues.

2. They can offer more protection without getting loopholes during communication. With copper wire cable systems, when the signal is broadcasted over the cable, there is the possibility that somebody who using high technology gadgets can detect the signal remotely while it is being broadcasted so there can be the issue of unwanted security intervention. However, with fibre optic cabling, this is not a problem because its dielectric nature cannot be sensed by remote detection unless a physical intervention will be placed inside its system.

3. They are actually the improved version of the copper wire cabling system because they are lighter in weight, have smaller diameter, have longer cables and they can be upgraded easily with less cost. They also have wider bandwidth so bigger volume of data can be transferred easily with quicker speed. This means that downloading and uploading data is much faster and more efficient.

4. They have EMI (electromagnetic interference) immunity because they do not have metallic wiring unlike the twisted copper wire cables.

So as you can see, fibre optic cabling, in many ways, has great advantages than the traditional twisted pair copper cable. However, we cannot totally eliminate the use of copper wire because as we have said, they are already scattered all over the globe and are still reliable. In the years to come, we can expect that half of the world's population will be using fibre optic cabling. As of today, some of the world's most industrialised countries have already started utilizing fibre optics.

Two kinds of fibre optic cable that are now available are the following:

• Multi-mode fibre. This has a large core diameter that utilizes light in broadcasting data through multiple paths. It provides multi-mode transmission capacity but because of the size of its core and limitation in its modal dispersion, it is only limited to short distances with minimum distance of 8 miles.

• Single Mode Fibre. This has a much smaller core diameter and it allows only one path for light when broadcasting. It can be used for long distance transmission far exceeding the capacity of the multi-mode and do not have limitations due to its modal dispersion.
