Abstract:The rate equation model is setup for the signal gain, pump absorption and output noise spectrum of bidirectional erbium doped fiber amplifier (Bi EDFA) including numbers of signals, pumps of arbitrary direction, amplified spontaneous emission(ASE) and inherent loss. The influences of erbium doped fiber length, input signal power, pump style and pump power on the gain characteristis of Bi EDFA are analyzed. Forward and backward noise figure for different pump style versus bidirectional input signal power is investigated. With these results, the optimal design for Bi EDFAs in optical communication systems and networks can be performed.
Keywords:erbium-doped fiber    bidirectional amplifier    gain    noise figure
