摘要： An optical transmission line for Raman-amplifying an optical signal by supplying pumping light. A range where the Raman gain coefficient takes on a maximum is a predetermined distance away from the end where the pumping light is supplied in the direction of the propagation of the pumping light. The power of the optical signal does not increase to the extent that the optical Kerr effect becomes remarkable at any point of the optical transmission line, does not decrease to the extent that the SN ratio remarkably lowers, and is ensured to have a large value at the end of the transmission line. A method for manufacturing the optical transmission line and an optical transmission system comprising the optical transmission line are also disclosed.

摘要： The method involves operating a wave guide in successive level by coupling of pumping radiation, and adjusting the pumping radiation according to characteristics. Stimulated brillouin scattering is originated in wavelength range of optical pulse. The pumping radiation is coupled with the wave guide opposite to propagation direction of optical pulse that is modified by another pumping radiation. Overall linear characteristic of a complete system is resulted from sequence of two levels to maintain the optical pulse to be delayed. An independent claim is also included for an optical signal delaying system including a source.
