摘要：The present invention relates to an optical fiber transmission line and the likecomprising a structure for enabling repeating sections to become further longer. Theoptical fiber transmission line comprises first and second optical fibers successivelydisposed along the traveling direction of signal light, and an optical multiplexer forsupplying Raman amplification pumping light to one of the first and second optical fibers.The first and second optical fibers are optically connected to each other. The secondoptical fiber has an effective area smaller than that of the first optical fiber, and a

chromatic dispersion and a length which are different from those of the first optical fiber.In particular, the respective lengths of the first and second optical fibers are

appropriately regulated so as to effectively suppress nonlinear phenomena other thanRaman amplification.
