As the reports and analysis of the market show, the manufacturers of telecommunication cable, including the optic type of fiber and ethernet, are showing unexpected and increasing production rates, especially in India, due to the demand for these cables. An optical fiber or optic fibre is a long thin transparent material, such as glass or plastic, that transmits light from one end to the other. Optical fiber has a much higher bandwidth than ordinary cables, and high-bandwidth image data, audio, and other data of up to 10 Gbps and above can be easily transmitted using optical fiber. Today, optical fiber communication is one of the most important means of information transmission because it has a wider bandwidth than copper cable and lower latency compared to satellite communication. 
The history of optical fiber manufacturing In recent centuries, the first people who thought of using light to transmit information experienced the propagation of light in the Earth's atmosphere. However, the existence of various obstacles such as dust, smoke, snow, rain, fog, etc. makes the propagation of optical information in the atmosphere a difficult problem. Later it was proposed to use tubes and channels to guide the light. The light in these channels is controlled by mirrors and lenses, but since adjusting these mirrors and lenses is a very difficult task, this work was also found impractical and rejected. Perhaps the first attempt at the development of optical communication systems was made by Alexander Graham Bell, who in 1880 just four years after the invention of the telephone, invented the photophone, a system that can transmit sound over multiple distances. Registered optical phones work by vibrating mirrors to modulate reflected sunlight. The receiver is a photocell. In this method, light is emitted into the air, making it impossible to transmit information over distances of more than 200 meters. Because of this, while Bell's device clearly worked, it was not a commercial success. The idea of using refraction to guide light (which is the basis of today's optical fibers) was first proposed in Paris in 1840 by Daniel Colardon and Jacques Barbinay. Furthermore, in 1870, John Tyndall described the properties of total reflection in his book: "When light enters the water from the air, it bends in a direction normal to the surface, and when it enters the air from water, it will bend away from vertical. 
If the angle between the beam and the vertical in the radiation from the water is greater than 48 degrees, no light will emerge from the water, and in fact, the light will be totally reflected from the surface of the water. the total reflection begins is called the critical angle. Englishmen Kaku and Cookham first proposed the use of glass as a medium. Their work is based on achieving speeds of around 100 Mbps or more on glass diffusion media. This transmission rate is associated with high energy attenuation. The two British researchers agreed that the energy was reduced to no less than 20 decibels. Although they failed to achieve the goal, the American company (Corning Glass) did. In the early 1960s, fiber optic communication was possible with the invention of the laser beam. In 1966, researchers theorized that light was guided in glass fibers, resulting in a way more efficient than traditional cables. Because optical fiber is lighter and cheaper than copper cable, and its transmission capacity is thousands of times greater than copper cable. Developments in fiber optic technology since 1980 have made optical communication a suitable choice. By 1985, nearly 2 million kilometers of fiber optic cables had been installed and operated worldwide.

Unexpected market reports in India
In the published reports in 2018, the optical fiber and related market were estimated to be worth $461.6 million in India. This market is anticipated to reach an unexpected number of $1.66 billion by 2026, expanding at a compound annual growth rate (CAGR) of 17.2% from 2019 to 2026. The term "optical fiber" refers to both the medium and the technology that is utilized in the process of transmitting information from one source to another via a thread of plastic or glass. Rapid flashes of light carry the information through optical cables as they go across the network. The light pulses are converted into binary values at the end of a fiber optic transmission that is at the receiving end. Optical fiber provides many benefits, including greater bandwidth, decreased size and weight, resilience to electromagnetic interference, data security, electrical isolation, and a number of other benefits. In addition to their employment in communication applications such as telecommunications, utilities, community access television (CATV), and the military, these are also utilized in non-communication uses such as sensor technology, fiber optic lighting, and other similar applications. In 2018, the market for optical fiber accessories was valued at $303.2 million, and it is anticipated that it will reach $741.9 million by 2026, expanding at a compound annual growth rate (CAGR) of 11.7% from 2019 to 2026. It is projected that the primary drivers of growth for the Indian optical fiber and accessories market would be an increase in the penetration rate of broadband connections in India as well as a rise in the demand for faster and more advanced networking and network services. 
In addition, an increase in demand for fiber optics and sensing applications for a variety of uses, a high demand for optical fiber cable (OFC) in the information technology and telecommunications sector, an increase in internet penetration, and a surge in the adoption of fiber to the home (FTTH) connectivity all contribute to the growth of the industry. The expansion of the market is anticipated to be hampered, however, by the high cost of installation and the increasing popularity of wireless communication technologies. On the other hand, increasing government investments in fiber optic network cable infrastructures are anticipated to present key chances for the advancement of the optical fiber and accessories market in India during the course of the forecast year. For example, the government of India has been investing in OFC network infrastructure in order to boost internet penetration throughout the country.
