Multimode and single mode fiber-optic cables
One of the basic criteria of optical equipment classification is the type of the fiber optics with which it works. It is connected with the type of transmission of light in the fiber core - single-mode or multimode. Transmission of light in optical fibers is based on the phenomenon of total internal reflection. The core, usually made of doped glass, is the center through which light travels along, while the fiber cladding is made of pure glass. Such combination of materials is dictated by their refraction indexes. To achieve total internal reflection, the refraction index of the cladding ...

Optical power budget in a fiber-optic communication link
The most important task in the design of fiber optic link is to determine the maximum range of the optical transmission path, being in fact the balance of optical power in the link. Balance of power is a comparison of the power at the input of the optical link with the losses in fiber optic cables and other path components. This will help to find the optimal parameters of transmitting and receiving devices to ensure proper signal transmission.
