Right now low loss fiber optic systems supply practically unlimited bandwidth and exclusive advantages more than all previously created transmission media. The simple optical transmitters convert electrical signals into modulated light for transmission over an optical fiber. The most common devices used as the light source in optical transmitters are light emitting diode. Fiber optic light supply make a great use of this, as light emitting diodes have comparatively huge emitting areas and utilized for moderate distances. Fiber optic light source prove to be economical.

A fiber optic light source device is mounted on a package that enables optical fiber to couple as considerably light as achievable into the fiber. In some instances a tiny spherical lens is also fitted to collect and focus each possible light onto the fiber. LEDs i.e. light emitting diode and light diodes operate in infrared portion of electromagnetic spectrum. Their operating wavelengths are selected according to the want. Fiber optic light supply is trustworthy and the most frequent wavelengths employed by fiber optic light source these days are 850 to 1300 nanometers or in some circumstances even 1500 nanometers. Both LEDs and LDs (light diodes) are comptia certifications obtainable in 3 wavelengths.

There are two methods via which light can be coupled into the fiber optic light source. One particular is by pig-tailing and the other is putting the fibers tip in very close proximity to an LED or LD. Given that the only carrier in these systems is light there is no danger of electrical shock to the personnel repairing broken fibers.

Principal function of fiber optic light source is to allow the light pulses move in fiber and works on the principle of total internal reflection, which states that when the angle of incidence exceeds a vital value light cannot get out of the glass instead it bounces back. The fiber optic light source works on this principle as it enables to transmit data down fiber lines in the form of light pulses.

There are a lot of kinds of sources obtainable that act as a fiber optic light supply. A fiber optic light supply generally comes in a rugged splash proof case and has single switch operation. A fiber optic light source has mixture supply for showing on or low battery. A single battery in a fiber optic light supply supplies more than 40 hours of operation in case of stable temperature compensated LED with 850 nm and/or 1300 nm fiber optic light supply provide. They supply 40 dB measurement ranges when utilised with Fiber OWL or Micro OWL. There are also laser models available in this category.

In case of 1310 nm or 1550 nm output supplies which are temperature compensated, a single battery supplies over 60 hours of operation. It gives 50 dB measurement range when utilised with Fiber OWL or Micro OWL.
