VERSTÄRKER FÜR OPTISCHE NETZWERKE UND VERFAHREN

摘要

A system for distributing optical signals comprises a plurality of optical splitter stages each operable to passively split one or more signals into a plurality of signals. At least one splitter stage comprises an amplification stage, including a plurality of gain media operable to amplify a signal with pump power. A first amplified splitter stage module is operable to passively split and amplify a first ingress signal into a plurality of drop signals. A second amplified splitter stage module is operable to passively combine a plurality of add signals and to combine those signals with a filtered pass-through signal.
