Abstract :
The twin-core erbium-doped fiber amplifier has been studied by analysing the theoretical model and simulating the characteristics of the amplifier. It is found that the twin-core erbium-doped fiber amplifier can provide higher gains for small signals while lower gains for strong signals at the same time, which equalizes the output signal level in a wavelength-division-multiplexed or a optical frequency-division-multiplexed system. Furthermore, the twin-core erbium-doped fiber amplifier chains also stabilize the signal level and self-heal extra channel loss. It seems that the twin-core fiber amplifiers earn excellent properties when used in multi-channel ultra-high-bit-rate optical transmission systems
