Three most important requirement for sourses for Optical Fiber Communication Link


  1. The source wavelength should correspond to the low-loss windows of silica viz.around 1.30 micro.m and 1.50 micro.m because the low fiber loss yield the larger repeater spacings.
  2. The spectral linewidth should be as small as possible typically <1nm
  3. It is possible to modulate the source at speed in excess of several 1Gb/s.To meet this requirement, one can either choose a suitable source that can be directly modulated or use an external modulator in tandem with a source that gives steady power output.
