Optical communication in the eyes of a newcomer to the industry

In my work, I have been asked countless times what optical communication is. To understand optical communication, we first need to understand what communication is.
From satellites to SIM cards, communication technology covers every aspect of our lives. Mobile communication, fiber optic communication, microwave communication, satellite communication, and computer communication all belong to one part of communication.
On the first page of the book "Principles of Communication" published by Beijing University of Posts and Telecommunications, it says, "communication is the exchange of information." In fact, this sentence summarizes the essence of communication. The goal of communication is to enable anyone in the world to exchange information at any time and in any place.
In our daily lives, communication is everywhere: base stations, fiber optics, microwaves, satellites, Wi-Fi... all belong to one part of communication.
When you chat with your friends on WeChat, the information you send is transmitted to the other person through electromagnetic waves in the radio frequency band. But if we want to transmit a large amount of information, such as high-definition video or large files, radio waves may not be enough. This is where optical communication comes in.
Optical communication is a communication method that transmits information through optical fibers. It's like "packaging information in light" and then transmitting it to the destination through optical fibers. In short, optical communication is the use of light to transmit information to the other party.
Optical fibers are very thin glass or plastic wires that can transmit light signals. Light signals can be transmitted at high speeds in optical fibers, achieving very high speeds and bandwidth. Imagine optical fiber as an infinite capillary and information as a liquid flowing through the "liquid flow" of a light signal. This "liquid flow" can be modulated into different frequencies and amplitudes, just like adjusting the water flow from a tap at home, to transmit different information, such as sound, images, and data.
Optical communication is a communication method that uses light signals to transmit information. It can achieve high-speed and high-bandwidth data transmission, allowing us to watch high-definition videos, download large files, or conduct remote video conferences more smoothly and efficiently online.
With the advent of the information age, optical communication, as a high-speed, large-capacity, low-energy-consumption, safe and reliable communication technology, has been widely used in the field of communication.
When I think of optical communication, I always think of it as a fast and quiet highway connecting the world. The optical fiber in an optical communication system is like the road of this highway; optical devices are like various high-tech cars that can run fast and quietly in optical fibers; laser diodes are like the engines of these cars that generate strong power so that the light signals can be transmitted quickly; optical amplifiers, optical modulators, optical splitters and optical receivers are like the various parts of a car that can ensure the normal operation of the optical communication system.
Overall, optical communication is a very important technology that enables us to transmit information faster and more efficiently, just like making cars fly on highways. Optical devices are the key to implementing this technology, like engines, components and control systems on cars that allow the optical communication system to operate efficiently.
As a newcomer to the optical communication industry, I believe that optical communication has a very broad development prospect and application value. In the future, optical communication will play an important role in the communication field, and its scope of application will gradually expand. For example, with the advent of the 5G era, optical communication can be used to build 5G infrastructure and provide faster and more stable network connections to meet the needs of future wireless communication. In addition, optical communication will also have a wide range of applications in areas such as smart homes, the Internet of Things, and healthcare.
I hope this article has provided some small help in understanding optical communication, and I welcome everyone to join the ranks of communication professionals and progress together!
