What are the characteristics of optical fiber?

The characteristics of optical fiber include high bandwidth, low loss, immunity to electromagnetic interference, high security, small size and light weight. Detailed introduction: 1. Optical fiber has a very high signal transmission bandwidth and can transmit optical signals of multiple frequencies at the same time, so it can achieve high-speed data transmission; 2. The transmission loss of optical fiber is very low and can theoretically transmit hundreds of kilometers or even further. distance without loss of signal quality; 3. Optical fiber transmits optical signals and is not interfered by electromagnetic waves; 4. Optical fiber transmission signals do not produce electromagnetic radiation, nor are they eavesdropped by external electromagnetic waves, etc.

Optical fiber is a communication line used to transmit optical signals. Its characteristics mainly include the following aspects:

High bandwidth: Optical fiber has very high signal transmission Bandwidth, multiple frequency optical signals can be transmitted simultaneously, so high-speed data transmission can be achieved. Compared with traditional copper cables, optical fiber has a larger bandwidth and can meet higher data transmission needs.

Low loss: The transmission loss of optical fiber is very low and can theoretically transmit hundreds of kilometers or even longer without losing signal quality. In contrast, the transmission distance of copper cables is limited by factors such as resistance and electromagnetic interference, and the transmission loss is large.

Free from electromagnetic interference: Optical fiber transmits optical signals and is not subject to interference by electromagnetic waves. However, traditional copper cables are prone to interference from electromagnetic waves because signals are transmitted through current, which reduces signal quality. Therefore, optical fiber is superior in anti-interference performance.

High security: Optical fiber transmission signals will not produce electromagnetic radiation and will not be eavesdropped by external electromagnetic waves. In contrast, traditional copper cables produce electromagnetic radiation during transmission and are easily eavesdropped. Therefore, in some scenarios that require higher data security, optical fiber is more suitable.

Small size and light weight: Due to the use of optical signal transmission, optical fiber is smaller and lighter than traditional copper cables, making it easier to deploy and maintain. Especially in large-scale communication networks, the size and weight advantages of optical fiber are more obvious.

In general, optical fiber has the characteristics of high bandwidth, low loss, immunity to electromagnetic interference, high security, small size and light weight. These characteristics make optical fiber widely used in the field of modern communications and become the main communication line. In the fields of Internet, telecommunications, radio and television, etc., the application of optical fiber has become a mainstream trend, and with the continuous development of technology, the performance of optical fiber will continue to improve, providing better solutions for people's communication needs.
