Abstract
The invention discloses a remote pump transmission system which utilizes the Stimulated Raman effect to improve pumping performance and comprises a transmitting end, a receiving end of an optical transmission system and a remote pump amplifier in a transmission link, wherein the remote pump amplifier comprises a main pumping source, at least an auxiliary pumping source and a wave combiner. The auxiliary pumping source and the main pumping source are coupled in a bypass optical fiber through the wave combiner, which are used as pumping sources of the remote pump amplifier, in the transmission process of the optical fiber, the energy of the auxiliary pumping source is released to the main pumping source, thereby improving the pumping efficiency of the remote pump amplifier by the energy transition of the pumping light. The wave combiner is arranged on an entrance of a light signal channel where the bypass optical fiber is imported, the wave combiner is used for combining optical waves which are transferred by the auxiliary pumping source and the main pumping source, and the optical waves are input into the light signal channel by the wave combiner. The invention can effectively improve the efficiency of the pump, thereby reaching the purpose of improving the transmission distance of single-section.
Description
Technical field [0001] The invention relates to a remote pump transmission technology in the field of optical communication, in particular to a remote pump transmission system that uses stimulated Raman effect to improve pumping performance. Background technique [0002] In recent years, there have been more and more applications of remote pumping technology, mainly due to some special occasions, such as: when crossing straits, offshore, and crossing unmanned land (such as deserts, swamps, forests, etc.), it is impossible to provide power supply or establish relay stations. In the region, remote pump technology has become the only solution. The remote pump technology is to embed a section of erbium-doped fiber when laying the transmission fiber, and provide pump light at the remote site to realize the amplification of the transmission optical signal. Application methods: 1) Single fiber backward ROPA, 2) Dual fiber backward ROPA, 3) Dual fiber bidirectional ROPA. The remote pum...
