Technology of Optical Fiber

by:TBT     2020-08-26
Well who could have thought 2 or 3 decades back that we could convert our routine signals into light and then we can transmit that light from one place to another but someone surely did thought of that and he was successful and invented fiber optic cables. For those who do not know that what is fiber optic you should think of it as a pipe which is used to transfer light from one place to another.
Basic idea behind optic fiber is to get a very fast communication method and I think technology has succeeded in its mission up to some extent. As you are reading this discussion due to this amazing invention of optic fiber. There are basically three parts of optic fiber one is its glass core which is used to transfer light then there is an outer cladding which deflects the light inwards and do not allow any leakage of information and the third is plastic cover which is on the outer side and is used to protect the whole optic fiber.
Fiber optic cables are as thin as a human hair and they are always found in bundles. Mainly and commonly used fiber optics is of two types one is single mode and the other is multi mode. Well when you think of the optical fiber glass then it is not made from ordinary glass they are made from special glass which is called optical glass.
This glass is made form many complex chemical reactions and is tested heavily to ensure 100 percent performance. This technology is now being used widely across the world for safe and bulk data transfer. Initially it was developed by GE but then over the years all of its issues were resolved and today fiber optic is one of the safest and fastest means of data transfer.
As this is very advanced technology so it is not implemented at a personal level instead mainly fiber optic is used as the backbone of many networks. This technology is very costly and it requires lot of effort and expertise to install it. Optic fiber can carry signal up to 200 kilometers without any amplification which is pretty high as compared to copper or other materials but as I said this is very costly technology and still it is not being used for private use. Only big companies like telecommunication or internet providers use this source as its installation cost is high but it is durable and its maintenance cost is very low.
