Multimode fiber can transmit multiple modes of light. However, the dispersion between the modes is large, which limits the frequency of transmitting digital signals, and will increase with distance. Therefore, the transmission distance of multimode fiber is relatively short, generally only 2 kilometers. 1, the introduction of fiber optics The full name of the optical fiber called optical fiber English name is OPTIC FIBER, also called OPTICALFIBER, is the use of pure quartz (glass) with a...
The continuous development of technology has increased the amount of data transmission. How many dark fibers do we have now? Dark fiber refers to cables that have been laid but have not been put into service. In many cases, telecommunications companies will lay down the amount of fiber that they need in order to meet future needs and avoid the high costs associated with repeated fiber laying. Dark fiber may be leased to individuals or other companies for establishing optical connections between...

Fiber optics are the main body of the fiber optic lighting system. The function of the fiber is to transmit or emit light to a predetermined place. Fiber is divided into two kinds of end-emitting light and body light. The former is the light beam passed to the end point, through the taillights for lighting, and the latter itself is a light, forming a flexible optical fiber light is mainly used in hotels, bars, KTV, cafes, DISCO, cultural heritage lighting, waterscape security lighting and other...
