Multiplexer for the realization of not - equidistant intervals between the pumps waves lengths in the broadband raman amplifiers

摘要

A method for the production of pump shafts for the raman - amplification of a via an optical waveguide (4) guided signal, which has the following steps:– Providing a pump shafts generation in front of the direction (5) with at least one pump source, which is set up so that it pump waves with a first, second, third and fourth, can produce pump wavelength are equidistant from one another, whereby the pump shafts generation in front of the direction (5) is actuated in such a way that in each case at the first, second and fourth pump wavelength a pump wave (u, v, w) is produced, and that in the case of the third pump wavelength no pump wave is generated, so that overall a not - equidistant test pump channel grid is achieved.
