Fiber Optic Lighting – Light source plays an important role in optical fiber communication systems. It consists of fiber optic core system of the transmitter, optical fiber, and a receiver. Transmitter light source is modulated by a suitable drive circuit according to the signal to be transmitted. It is determined to choose the optical source of a particular application.
The important characteristic of the fiber optic lighting is a small spectral line width. This can dramatically affect the amount of dispersion which is directly proportional to the line width of the source. Fiber dispersion causes signal interference and greatly reduces the bandwidth capacity of the system.
There are different types of light sources, fiber optic lighting communications systems are usually used only good LED (light-emitting diode) or a laser diode (LD). LEDs and LDs have a small size, high energy efficiency and many other useful features. Lasers have monochrome color, which is comparable to the oscillator in this concept. Laser consists of an active way able to provide optical amplification and optical resonator that provides visual reactions necessary. Some manufacturers offer a choice of units for laser diode ranging from continuous wave, generator track, national inventory and more.
