REMOTELY OPTICALLY AMPLIFIED PON SYSTEM, OLT, AND RN, AND OPTICAL AMPLIFICATION AND GAIN-CLAMPING METHODS OF PON SYSTEM |
摘要 |
A remotely optically amplified passive optical network (PON) system, an optical line terminal, and a remote node, and an optical amplification and gain-clamping methods of the PON system are provided. The PON system generates pump light and transmits the generated pump light to an optical transmission line, amplifies primarily an optical signal by the pump light which pumps the optical transmission line, and amplifies secondarily the optical signal by the transmitted pump light which pumps a gain medium of a remote node while maintaining a gain of the optical signal by applying a gain-clamping method to the remote node.
