Diploma in Fiber Optic Communication Technology

Fibre-optic communication technology is an important area of study that takes a look at the need for optical fibres. It is used by telecommunication companies to transmit telephone, cable and internet signals and by industries like the medical profession and defence because of its high bandwidth. If you want to be at the forefront of cutting-edge technology, start today to learn more about this form of communication.

Fibre-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light. This process has become an essential part of our everyday lives as it is used in the telecommunication industry, therefore providing a technological foundation for societal communication. This course will introduce you to the different types of optical sources that are available, including why fibre-optic communication produces far more speed over longer distances and why it is more secure than traditional communication channels. While specific network capacities are privileged information, telecommunications investment reports indicate that network capacity has increased dramatically with fibre. Fibre optics has enabled the development of other technologies such as medical devices, ‘Internet of Things’ (IoT) devices and many others that require data to be transmitted back to a server. Even though there are many advantages to optical fibre, there are obstacles. One of the barriers is in the installation of the fibre itself, which is expensive.
Are you curious about the history of communication and how it has evolved through the ages? In this course, you will learn why we need optical communication in today’s world and discover the different wavelengths used in optical communication. In addition to this, the advantages and disadvantages of the different wavelengths used in fibre-optic communication and the various network topologies utilised for different situations will be discussed. This course will cover the different multiplexing schemes and explain how optical fibre carries information to and within data centres. Knowing the various parts of the block diagram and how to set up a link is important, along with how power is measured in a digital modulation unit. Alongside this, you will be exposed to theoretical scenarios and various formulas used to solve these scenarios and the setbacks of direct modulation lasers, specifically the chirp modulation and transient chirp and the effects when the data signal is being transmitted through a long optical fibre. Electro-optic phase modulation will also be presented. You will learn how to generate a high repetition rate. Additionally, you will learn about phase-shift keying and why it is the standard method for data modulation.
Fibre optics technology is widely used in medical procedures for non-intrusive surgical procedures; such as endoscopies. It is also being used in areas such as prosthetics to help the user perceive what they are touching. Fibre-optic cables use light signals rather than electrical signals and are far less likely to be affected by power outages and or electromagnetic interference. As a result, they are much stronger than copper wire, making them more impervious to the elements. As the use and demand for greater bandwidth and faster speed increases, there is no question that fibre optic transmission will bring more possibilities. There are many opportunities in the field of research as the need arises to expand and cater for these future needs. Fibre optics has changed our world in more ways than you can imagine and will possibly be the source of major breakthroughs, prompting greater technological evolutions. Do you like to work with computers, electronic gadgets and enjoy all types of technology? Are you curious about how things work and passionate about the digital world? Don’t wait! Begin this course today and become an expert in the field of fibre-optic communication and technology.
