Optical fiber is a bundle of glass or plastic that can transmit light over long distances, which is similar to cables used to carry electricity. Optical fiber is widely used in telecommunications, medical applications, sensing, data communications, and other fields. In fact, there are two types of transmission modes of optical fiber. They are single-mode fiber and multi-mode fiber.<\/p>\n\n\n\n
Single-mode fiber is designed with a small core diameter, offering a single pathway for light to travel. It only propagates along a straight line and has no reflection, which makes the transmission bandwidth higher, so it is suitable for large-capacity, long-distance systems.<\/p>\n\n\n\n
Multi-mode fiber can support the transmission of multiple optical signals. That can easily cause a large dispersion. And the bandwidth is lower because of the dispersion. Multi-mode fiber can bear harsh environments and transmit a large number of data in a short distance, which makes it suitable for industrial and medical communications.<\/p>\n\n\n\n
Both single-mode fiber and multi-mode fiber can transmit data or information. However, they have differences in physical structure and effects.<\/p>\n\n\n\n
Both the cladding diameters are 125\u03bcm. However, the core diameter of the multi-mode fiber is larger than that of the single-mode fiber.<\/p>\n\n\n\n
