Wavelengths in different bands
With the rapid development of 5G networks, the demand for network data transmission is increasing exponentially. As the underlying bearer network, the transmission capacity of optical networks is crucial to the development of 5G networks. One of the magic weapons to expand the transmission capacity of optical networks is to continuously dig deep into the available band resources of optical fibers, that is, to continuously expand the transmission path width of optical networks. The wider the transmission road, the transmission capacity of the optical network will naturally increase. Next, I will talk to you about these bands of optical fiber. T raditional band As the name implies, optical fiber communication is the communication in which light is used as an information carrier and optical fiber is used as a transmission medium. However, not all light is suitable for fiber optic communication. Different wavelengths of light (which can be simply understood as light with different colo
