Light Source

In fiber optics, a source of light (laser, LED, etc.)  is used to emit electromagnetic radiation in order to perform a specific task, whether detecting faults, breaks and microbends, characterizing link-loss or certifying LAN/WANs. As recommended by the ITU-T (G.983.3), light sources are also used to test PON networks at three different wavelengths (1310/1490/1550 nm).
