What are the two types of single-mode fiber loss
For single mode fiber, the fusion splicing loss typically can be less than 0. This allows the cables to transmit data over much longer distances than multimode fibers, with less signal loss and better quality. Fiber attenuation, which is also called signal loss or fiber loss, is the consequence of the intrinsic properties of an optical fiber (multimode and single mode fiber). Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber).
