Today, DOME Fiber Closure suppliers come to share the principle of fiber:

The optical fiber actually refers to a core made of a transparent material and a cladding made of a material having a slightly lower refractive index than the core, and the optical signal injected into the core is reflected by the cladding interface. The optical signal propagates the advancing medium in the core. It is generally a symmetrical cylinder of a multilayer dielectric structure composed of a core, a cladding and a coating.

Fiber has two main characteristics: loss and dispersion.

The loss or attenuation (dB/km) per unit length of the fiber is related to the length of the transmission distance of the fiber-optic communication system and the distance of the relay station.

The dispersion response of the fiber is delayed or pulse broadened, which is especially important for digital signal transmission. The pulse spread per unit length (ns/km) affects a certain transmission distance and information transmission capacity.
