The way that fiber optic technology works is a fascinating subject. If the idea of how it works is moving inside your mind as fast as the light inside the optic cable itself then don’t worry, that’s this article is for. Let’s start at the very beginning so we can best explain. The easiest way to figure out fiber optics at least at the basic level is to get an explanation of the process. Fiber optic technology works by having engineering meet science head to head. Light is then sent through optical fibers via total internal reflection. The fiber’s core is then taken care of by a process called cladding. Cladding occurs when substances of a lesser refractive index become closer to a greater refractive index’s core material. The detachment of the core and cladding could be an instant thing or there may be a buildup to the two coming undone. The refractive index is a way of figuring out the light speed of a substance. Inside of a vacuum the light travels at its top speed. Let’s think outer space for a second. In that case speeds can reach up to 186,000 miles per second. The figuring out of a refractive index happens when the vacuum’s speed of light is divided by another medium’s speed of light. The core’s value ends up around 1.48. The end result for the refractive index is 1. The cladding for an optical fiber is 1.46. When a greater refractive index occurs the light moves even slower. How else does fiber optic technology work, read on! When light travels inside an enclosed medium the light is cloned when it comes into touch with a steep angle. Therefore optical fibers can hold onto the light that’s within the core. When this happens the light bounces inside of its set limits. Timing is crucial for this light travel and if the timing is off the light travel will be immensely hindered inside of the fiber. Inside of what is called the acceptance cone there are angles that work within the fiber. The acceptance cone’s size is the result of the refractive index’s difference between the cladding and core of the fiber. In short, there’s only so much that an angle of light can do to enter a fiber. This is to keep the light circulated inside the central part of the fiber and do what it needs to do. Fiber optic technology riles on the use of three different grades of fiber and each fiber is intended for different applications. The first are single mode fibers and they’re made solely of glass and are used for optic based networks that go a long instance. The next type of fiber is multi-mode fiber, which is sometimes made with a hybrid of plastic and glass or just glass only. Multi-mode fiber is made for networks in a 500 meter range. Of the two, single-mode is the costlier of the two. Then there’s special-purpose optical fiber such as photonic crystal fiber that’s used to bend light in order to keep it inside of the fiber. Well that’s a wrap and we hope that fiber optic technology hasn’t scared you because it truly is amazing! Its inner workings are vast and in depth. We hope that this article serves as a suitable jumping point for a subject that is of great variety and interest until next time thanks for reading!
