<transcript><audio_0>hello all myself dr a rd smoke from department of engineering sciences in this video we are going to learn the concept basic principle of optical fiber</transcript><caption><image_1>The image is a photograph of a cityscape with buildings and trees. The sky is blue and the buildings are white and appear to be modern. In the center of the image, there is a large building with a red and white logo that reads "AISMS" and "Basic Principle of Fiber Optics". Below the logo, there are two smaller logos that read "Dr. A.R. Deshmukh, Department of Engineering Sciences". The image appears to be taken from a high vantage point, looking down on the city below.</caption><caption><image_2>The image shows two types of optical fibers. On the left side, there is a blue fiber optic cable with multiple layers of fiber optic cables attached to it. The cable is labeled with the text "Optical Fibers" and on the right side, it is labeled as "Core-the thin glass center where light travels. Cladding - optical material (with a lower index of refraction than the core) that reflects light back into the core. Buffer Coating - plastic coating on the outside of an optical fiber to protect it from damage."

On the bottom right side of the image, there are two images of the cable, one showing the fiber optic fibers and the other showing the different types of fiber cables. The fiber cables are shown in different colors - blue, green, yellow, and black. The text on the image explains that fiber optics are often long-lasting and can be used in various applications.</caption><transcript><audio_3>fiber optics are often long stand of very pure glass they are very thin they are about size of human hairs and due to the small size 100 to thousands of these</transcript><transcript><audio_4>fiber can be arranged in a bundles as we can see here and these bundles can we can say in day-to-day life optical cables and these optical fibers can transmit the light for a very long distance uh</transcript><transcript><audio_5>if we want to understand the construction of this optical fiber there are three main parts of this optical fiber one is core second is cladding and third is buffer coating so the core is made up of glass</transcript><transcript><audio_6>with a very high refractive index so that we can say that core are denser medium and the light which passes from for a very long distance they passes through the core</transcript><transcript><audio_7>cladding is outer surface to the core which is made up of optical materials but however the these are the rarer medium the material which is used to prepare the cladding</transcript> hello all myself dr a rd smoke from department of engineering sciences in this video we are going to learn the concept basic principle of optical fiber fiber optics are often long stand of very pure glass they are very thin they are about size of human hairs and due to the small size 100 to thousands of these fiber can be arranged in a bundles as we can see here and these bundles can we can say in day-to-day life optical cables and these optical fibers can transmit the light for a very long distance uh if we want to understand the construction of this optical fiber there are three main parts of this optical fiber one is core second is cladding and third is buffer coating so the core is made up of glass with a very high refractive index so that we can say that core are denser medium and the light which passes from for a very long distance they passes through the core cladding is outer surface to the core which is made up of optical materials but however the these are the rarer medium the material which is used to prepare the cladding
