Distortion of a Broadband Intensity Signal During its Transmission Through a Chain of Lumped Amplifiers Due to their Saturation,
Abstract
Experiments on soliton pulse transmission through optical fiber on the distance of up to 10000 km confirm the possibility of realization of ultra long high-bit-rate soliton communication systems. At the present moment it seems most reliable to compensate the optical fiber losses with the help of lumped erbium-doped fiber amplifiers, periodically placed along all the transmission distance. As the value of the erbium fiber amplifier saturation power is not very high ( approx. 0.5 mW ), than the influence of the amplifier saturation could affect on the signal transmission in the soliton regime. The amplifier saturation in soliton communication systems could result in decreasing of the soliton sequence signal-noise ratio. This effect can be accumulated after transmission through a large number of amplifiers ( > 300 for L approx. 10000 km).
