What is Active Optical Fiber?

In the field of optical communication, special optical fiber has gradually become the star of the communication industry with its unique performance and wide application. And one of them, active optical fiber, has become the new favorite in the field of optical communication with its high efficiency, long-distance transmission and anti-interference characteristics. Today, let us step into the world of active optical fiber and explore its characteristics and advantages under the mysterious veil.

What is Active Optical Fiber?

 

Active optical fiber, as the name suggests, is an “active” optical fiber. The biggest difference between it and ordinary optical fiber is that optically active materials are added inside. It enables direct conversion of light. The emergence of this kind of optical fiber has greatly improved the transmission efficiency of optical communication systems.

Advantages of Active Optical Fiber

 

1.Longer transmission distance

Because optically active materials are added inside the active optical fiber, direct conversion of light can be achieved. As a result, the transmission distance of optical signals has been greatly improved. Compared with the transmission distance of hundreds of kilometers of traditional optical fibers, the transmission distance of active optical fibers can reach thousands of kilometers, or even farther.

2.Higher transmission rate

The transmission rate of active optical fiber is much faster than that of traditional optical fibers. The transmission rate of traditional optical fiber is generally around tens of Gbps. The transmission rate of active optical fiber can reach hundreds of Gbps, or even higher.

3.Stronger anti-interference performance

The anti-interference performance of active fiber optic is much stronger than that of traditional optical fiber. Because optically active materials are added to it, direct conversion of light can be achieved. Thus, the attenuation and distortion of optical signals during transmission are avoided.

4.Higher security

The transmission security of active optical fiber is much higher than that of traditional optical fiber. Because it can achieve direct conversion of light, optical signals cannot be stolen or tampered with during transmission. Thus, the security of information is guaranteed.

Application of Active Optical Fiber

 

Due to the unique advantages of active fiber optic, its application scenarios are very wide. For example, in the communications industry, active optical fiber is widely used in long-distance, large-capacity optical communication networks. In the industrial field, active optical fiber is widely used in high-end fields such as robots and automation equipment. In the medical field, active optical fiber is widely used in medical equipment, medical devices and other fields.

Development of Active Optical Fiber

With the continuous development of science and technology, the technology of active fiber optic is also constantly improving. In the future, active optical fiber will develop towards faster transmission rates, longer transmission distances, and lower costs. At the same time, with the continuous development of emerging technologies such as 5G and the Internet of Things, the application scenarios of active optical fiber will also become more extensive.
