What is optical laser communications?

Optical spectrum uses light as a means of transmitting information via lasers. Optical communications benefits include being faster, more secure, lighter and more flexible. Optical communications challenges include a need for precise laser beam accuracy and Earth's atmosphere interference, such as clouds.

Why is laser communication better?

Laser communications systems provide missions with increased data rates, meaning they can send and receive more information in a single transmission compared to traditional radio waves. Additionally, the systems are lighter, more flexible, and more secure.

Can lasers be used for communication?

Laser communication has the advantages of small transmission loss, long transmission distance, high communication quality, large communication capacity, strong confidentiality and light structure. It is mainly used for ground communication, global communication and interstellar communication.

What are the benefits of laser and optical communication?

➨It has very minimum signal leakage. ➨Laser based fiber optic cables are very light in weight and hence are used in fiber optic communication system. ➨It is less damaging compare to X-rays and hence widely used in medical field for treatment of cancers.
