Introduction
Also called as fibre optic cable, optical fibre is essentially quite similar to the very commonly used electrical cable. It contains several optical fibres which are used to carry light. The cables are protected using a coating of plastic and then grouped together and placed inside a thick tube. The uses of these cables are vast. Today, optical fibre cables are used in long distance telecommunication, or providing high speed internet access or data connection in a building like an office or even in-home use.
Design and quality
Optical fibre works on the principle of total internal reflection where the light basically does not refract outside the fibre material and the entire energy is conserved inside the fibre itself. This provides high intensity signals. Total internal reflection occurs due to the presence of two layers called the core and the cladding layers. Due to their different refractive indices, the light goes through total internal reflection. Usually the cladding layer is coated with a polyamide or an acrylate polymer. Depending on its use, the cables are protected with several layers of coating in order to reduce cross-talk and reduce flare in imaging applications. Generally, optical fibres are quite tough but this strength is heavily reduced due to inevitable flaws occurring during the manufacturing process. To overcome this, the strength of the fibre cable initially must be set to such a level where it can sustain all the proceeding stress it will receive due to manufacturing, handling during installation, and general environmental conditions as well.
Jacket and fibre material
The jacket coating depends on the type of application the cable is used for. Mainly the jacket tries to protect the cable from mechanical damages, UV radiation, or any kind of chemical interaction. Polyvinyl Chloride, polyethylene, polyamide, etc. are few of the substances used for making these jackets. The fibres on the other hand are mainly made of two types of materials, namely glass and plastic.
Active Optical Cable
AOC is a technology which deals with electrical to optical transformation. It highly 
increases the efficiency of these cables without any sort of collateral damage. The 10g AOC is one such cable which makes our communication systems much faster. The 10g AOC was introduced to serve as a replacement to traditional copper cables. Copper cables are generally massive and very heavy, with the performance being reduced due to electromagnetic immunity and the electrical signal’s nature. These cables are the best solutions for high speed computing and even for storage use. The 10g AOC has several advantages over normal cables such as being lightweight, providing higher performance, low consumption of power, less loss due to interconnection, no electromagnetic interference, flexibility, etc. Moreover, these optical fibre cables can be available in various lengths as well.
Conclusion
Thus, we can clearly see why the use of optical fibre cables in recent times has increased in such a quick period. With cables like the 10g AOC, one can get the best of data speeds with almost no loss of power or electricity.
