Fiber Cabling Briefing


Fibre optic lightFiber cabling, sometimes called optical fiber cabling, is comprised of several optical fibers and encased within a plastic jacket. These optical fibers are highly flexible and work as a waveguide, allowing light to transfer from one end of the cabling to the other. This kind of material is ideally suited to communications as it does not experience the same communication break-down or communication loss of metal wires, which may be hindered by electromagnetic forces. Unlike standard network cabling, however, optical fiber is more difficult to join and must be mechanically spliced, often through using heat. For short cables meant for indoor use, the ends are typically fitted with special connectors to allow the cabling to interface directly with the intended device.

When selecting fiber cabling, first determine if you need single mode or multimode cabling. Most devices will require multimode cabling, but some extreme projects may necessitate single mode. Determine next what fiber count you require, and always aim a little higher to anticipate future bandwidth. Next, measure out the length you will need for your device; keep in mind that fiber cabling is often kept at factories and may require a direct purchase. Lastly, the jacket colors are fairly standardized with orange indicating multimode, black indoor/outdoor and so on.

While there are many benefits to using fiber cabling, the cost does reflect those benefits, but that cost is off-set over long-term applications. Bringing higher bandwidth to the table along with lower installation and maintenance costs, the actual cabling will run more than traditional copper, but you will still save money overall. One meter of multimode cabling can average about 10 dollars while single mode will run a little higher. While many cables are purchased directly from the factory, there are numerous sites online that sell cables for personal use at a low cost to the consumer.

How does an optical fiber transmit light?

Transmission of light through an optical fiber is similar to the transmission of light through a hallway. When you have to illuminate a long straight hallway you just have to point the beam straight down the hallway as light rays always travel in a straight line. But to illuminate a hallway which is a winding one with multiple bends, you need to line the walls with mirrors and angle the beam so that it bounces from side to side all along the hallway. This is exactly what happens in an optical fiber. Optical fibers make use of total internal reflection to confine light within the core of the fiber. The core of an optic fiber has a higher refractive index than the cladding enhance the light suffers total internal reflection. Although the cladding does not carry light it is nevertheless an essential part of the fiber. The cladding is not just a mere covering, it keeps the value of the critical angle constant throughout the whole length of the fiber.

Propagation of light in an optical fiber

All the energy in the ray of light is reflected into the core and none escapes into the cladding. The ray then crosses to the other side of the core and because the fiber is more or less straight the ray will meet the cladding on the other side at an angle which again causes total internal reflection. The ray is then reflected across the core again in the same manner. In this way, the light zigzags its way along the fiber thus the light gets transmitted to the end of the fiber. Because the cladding does not absorb any light from the core, the light wave can travel great distances. However, some of the light signal degrades within the fiber mostly due to impurities in the glass.

Some Interests Facts

The maximum angle of incidence in air for which all the incident light is totally reflected at the interface of a pair of media having refractive indexes. Mu 1 and Mu 2 is called the angle of acceptance. Fiber attenuation is defined as the loss of light energy during its transmission through an optical fiber due to absorption by the impurities in the glass fiber. Optical fibers are used to transmit communication signals. In endoscope used to investigate interior organs which cannot be viewed directly and in photometers.
