91-km attenuation-free transmission with low noise accumulation by use of distributed erbium-doped fiber

Transparency of a 91-km distributed erbium-doped fiber is achieved with 0.46 mW/km of pump power at a signal power of -12 d Bm. The accumulation of amplif ier noise is measured to be smaller than the minimum noise accumulation that can be achieved in a 91-km link with two lumped amplifiers separated...

Zusammenfassung:Transparency of a 91-km distributed erbium-doped fiber is achieved with 0.46 mW/km of pump power at a signal power of -12 d Bm. The accumulation of amplif ier noise is measured to be smaller than the minimum noise accumulation that can be achieved in a 91-km link with two lumped amplifiers separated by 45 km.
