Amplified spontaneous emission in fiber optic lines using Raman amplifiers

  • 1 Aviation Faculty, National Military University „Vasil Levski“, Dolna Mitropolia, Bulgaria


New methods for a regeneration and an enhancement of the optical signal have been developed all over the world. The main reason is the increasing bit rate and optical fiber length. A new method for optical amplifiers based on nonlinear effects is discussed in this report. Amplification changes are surveyed as a function of the signal power at different pump configurations and different wavelength.
