Optic Fiber Loss
After the optical signal is transmitted through the optical fiber, the optical power is reduced due to absorption, scattering, and the like. Fiber loss is an important indicator of fiber transmission and has a decisive influence on the transmission distance of fiber communication.
An important issue in achieving fiber-optic communication is to reduce the loss of the fiber as much as possible.
The so-called loss refers to the attenuation per unit length of the fiber, and the unit is dB/km. The fiber loss has a direct impact on the transmission distance or the distance between the relay stations. Therefore, understanding and reducing the loss of the fiber has great practical significance for fiber-optic communication.
The loss factors of optical fibers mainly include absorption loss, scattering loss and other losses.
