Fiber Optic Cables: A Brief Introduction

Fiber optics has been around for many decades and was once considered a new discovery. Modern telecommunications systems have made use of the technology to transmit signals faster over longer distances with less loss of signal. It is also possible to transmit signals by fibre optics even in case of radio waves, since they do not pass through metal.

A fibre optic cable is made of thin glass or plastic, and its diameter depends upon the length and weight of the material to be enclosed. Its inner surface is highly reflective so that light rays have an easier time penetrating the glass fibers. Light, as most people know, is a molecule and the molecules in different kinds of matter each have different polarizations. The light can only pass through a single polarized molecule at a time. In this case, the light is divided into electrical and optical beams. Fiber optics enables us to send the light by using a series of thin optical fibers.

 

Fiber optics enable us to send information from one point to another over long distances without the loss of quality. The signals are undamaged and intact after they pass through the glass fiber. They are also protected from interference so they can carry signals to their destinations with minimum loss. The light signals transmitted are very clear and last longer compared to other methods of transmitting signals over long distances.

 

There are two major types of fiber optics: optical fiber technology used in computer cables and coaxial cable system. Computer cables have been built with high quality fiber optics since they are capable of transferring data quickly. They are also durable and provide greater distance between the input devices. However, coaxial cables are thinner than any other type of cable and thus consume less space.

 

Fiber optics is used in the manufacturing process to send light signals long distances. Fiber optic wire is used in television sets, radio receivers and telephones. Since it transmits light signals with high bandwidth, it is the best for long distance communication. You can send images and pictures, videos and sound across the Internet even with slow connection speed using optical fiber technology.

 

Fiber optic cables have an insulation which reduces electromagnetic interference. Light passes through it with little or no loss of quality. They are resistant to electrical interference, so they are ideal for use in electronic components like microchips, cameras and computer monitors. Fiber optic cables transmit signals at much higher bandwidth compared to other medium like cable and phone line. This makes them useful in data transmission over large distances.

 

Some of the advantages of fiber optics are better signal transfer, greater capacity, and long lasting. It also has low cost associated with its manufacture. Since light travels at greater speeds, it requires more space. The smaller the diameter of the cable, the greater the amount of fiber optic cables needed to transmit signals. Also the longer the cable, the lower the weight, which makes it practical for use in electronic components.

 

Fiber optics are mostly available in two types called single mode and multi-mode fibers. In single mode construction, a single fiber is utilized to transmit light. In multi mode construction, multiple fibers are utilized to transmit light. It is mainly used in applications where bandwidth is crucial like in computer networking and telecommunications. In simplex fiber optic cable constructions, strands of optical fiber are laid down in clumps and then they are bundled together. These strands are further treated with an adhesive agent and a lubricant which make the cable roll easy to handle.
