摘要：Optical amplifiers are typically disposed along the transmission path of an optical system. If a large number of optical amplifiers, e.g., eight, are so disposed, then it is likely that an appreciable level of so-called power divergence will occur among the optical signals forming a composite optical signal that traverses the path. Disadvantageously, when the composite signal is received at a destination and demultiplexed, a number of the demultiplexed optical signals will contain components of the other demultiplexed optical signals as a result of such power divergence. This problem is readily handled using a facility which greatly suppresses such components in a demultiplexed optical signal.
