Fiber optic technology, including fiber optic cable, is one of the transmission mediums which have the rapid growth. Nowadays, there are a lot of industries which utilize the fiber optic technology. It is with the consideration that this technology is able to provide you high-definition broadcast with the resolution of 1080p.
Fiber optic technology is widely applied for a wide range of applications such as backbone, horizontal and desktop. It would be able to perfectly work in any applications which needs long distances, high bandwidth, and also complete immunity for the electrical interference. Therefore, this fiber optic technology is ideal for systems with high data rate such as multimedia, Gigabit Ethernet, and also Fiber Channel. In addition, it is also ideal to be used for the applications which need bandwidth-consuming data files in long distances.
Fiber optic technology is able to convert the conventional signals of electrical data into an adapted light beam, introduced into the fiber and also transported through the very small diameter plastic fiber to a receiver. It is then changed the light back to the electrical signals. The fiber is able to bring the light signal at the lowest loss since it is based on the light refraction and reflection.
The Principles of Fiber Optic Technology
Furthermore, fiber optic technology has some principles. The light which passes through some mediums is then affected by the interface of the two materials. The different speed of the light during the travel through some materials can cause the above process to happen. Thereafter, each of the material is then described in refractive index term. This is a ratio of the light’s speed in the material to the free space.
The correlation of those two refractive indices of the fiber optic technology will then determine the critical angle of the interface of the two materials. When the ray of light crashes an interface, there will be three actions occur in which of the action highly depends on the incidence angle of the light ray with the interface. The ray of light would be refracted then bound to the material which has the higher refractive index.
When the angle of the incidence is perfectly the same as the critical angle, the light ray will pass through the interface travel. And when the angle of incidence is larger than the critical angle, the light ray will reflect. The refractive index of the vacuum is considered to be one. However, the refractive index of air is slightly larger. Meanwhile, the index of the refractive of the water is around 1.33. The glass has refractive index of 1.5. However, the value of the refractive index of the glass can possibly be manipulated through the control of the glass composition.
The Characteristics of The Fiber Optic Technology
Fiber optic technology is able to let the data signal to transmit through by making sure that the light signal has entered the fiber at an angle which is larger than the critical angle of the interface of the two glass types. The optical fiber basically has three parts, the center core, the surrounding glass, and the diameter of the core. The center core is made of the pure glass with the refractive index of 1.5.
