For fiber-based cabling, data transmission is based on the light as the transmission medium. We know that in the transmission process, the loss of light power is inevitable. When connecting components, there will be insertion loss; when optical signals are transmitted over fiber optic cables, there will be attenuation. In addition, the material of optical components and the operation during the cabling have an influence on the amount of loss, which will determine the level of network...
