The optical amplifier combiner arrangement is used in a tree-like optical network (APON) consisting of the cascade connection of dedicated branches of the arrangement and of a common branch. The arrangement is coupled between a plurality of optical network users and on optical line terminator, viathe dedicated branches and the common branch respectively. The network enables upstream transmission of information signals from the optical network users to the optical line terminator. The optical amplifier combiner arrangementincludes for each branch of the dedicated branches: - an optical amplifier to amplify an information signal with a gain value and tothereby generate an amplified information signal with a predetermined power level, - an optical switch on/off coupled between the optical amplifier and an optical combiner to pass the amplified information signal when the information signal ispresent and to interrupt the branch when the information signal is not present The optical combiner is included in the arrangement to combine all amplified information signals according to a multiple access technique and to thereby generate an outgoing optical signal for application to the optical line terminator.
