Optical fibers are utilized widely for data transmission systems because of their capacity to carry extensive information and dielectric nature. Network architectures utilizing multiple wavelengths per optical fiber are used in central, metropolitan, or broad-area applications to link thousands of users with a vast range of transmission speeds and capacities. A powerful feature of an optical communication link is sending several wavelengths through the 1300-to-1600-nm range of a fibre simultaneously. The technology of integrating several wavelengths onto a similar fiber is called wavelength division multiplexing (WDM). The principle of WDM utilized in concurrence with optical amplifiers has an outcome in communication links that permit rapid communications among users in the world's countries. This paper presents an overview of the challenges of fibre optic Review Article Kareem et al.; AJRCOS, 7(4): 48-58, 2021; Article no.AJRCOS.67395 49 communication. This paper offers an outline of the areas to be the most relevant for the future advancement of optical communications. The invention of integrated optics and modern optical fibers takes place in the field of optical equipment and components.

As we approach the half century mark for the dawn of the era of optical communications, it is appropriate to take stock of the journey of discovery and application of this empowering technology. As with most new technologies, the engineering challenges associated with its assimilation into the existing infrastructure have been as significant as the scientific advances within the invention of the laser itself. ITU-T has been active in the standardization of optical communications technology and the techniques for its optimal application within networks from the infancy of this industry. However, it is not always easy to find out what has been covered, and where it can be found. This manual attempts to aggregate all of the available information on ITU-T's work.

Optical Fiber was initial created during the 1970s, the utilisation of and demand for optical fibber have boosted hugely. The uses of optical fibber these days are quite many. With the explosion of data traffic because of the net, electronic commerce, computer networks, multimedia, voice, data, and video, the necessity for a transmission medium with the information measure capabilities for handling such vast amounts of data is paramount. fibber optics, with its comparatively infinite information measure, has proved to be the answer.

Abstract: Photonic networks are probably the most appropriate solution to meet growing bandwidth requirements in the present as well as in the future Internet. The very high bandwidth of optical fibers can be exploited to some extent by using advanced modulation formats and by multiplexing the data either in the wavelength, in the time, or in the code domain.
