A Good Optical Fibre Source Should have the Following Characteristics:
1.Light source should be highly directional to make the launching of light into an optical fiber easy.
2.It should emit light at wavelengths where the optical fiber has low losses and low dispersion. The detectors should also be efficient at these wavelengths.
2.It should emit light at wavelengths where the optical fiber has low losses and low dispersion. The detectors should also be efficient at these wavelengths.

3.It is also required that the optical source must couple enough optical power to overcome losses in fibre in the connectors. Not only this, after these losses enough power should be left to drive the detector.
4.The optical source should be linear to minimize the distortion and noise.
