摘要： A two-way optical amplifier system amplifies upstream and downstream optical signals in a passive optical network (PON). The downstream optical amplifier system includes an optical amplifier (EDFA), configured and arrange to amplify the downstream optical transport signal. The upstream optical amplifier operates in burst mode and includes an upstream transport fiber receiving an upstream optical transport signal, an optical source coupled to the upstream transport fiber to generate a saturating optical input signal that is combined with the optical transport signal and establishes a baseline reference level for AGC of the optical transport signal, a PON input receiving an incoming PON RF return signals, a first optical amplifier configured and arrange to amplify with AGC and equalize the PON RF return signals with the optical transport signal, a beam combiner configured and arranged to combine said equalized PON RF return signals with said optical transport signal, and a second optical amplifier configured and arranged to amplify the optical transport signal including said equalized PON RF return signals.
