<p>An optical system (10) including plural optical processing nodes (14) in optical communication via a plurality of signal varying devices (12). A first signal varying device including an optical fiber (30) configured to produce Raman scattering/gain in a signal wavelength range and a first signal variation profile. A first pump (12) with multiwavelengths output stimulates Raman scattering/gain within the signal wavelength range. A second signal varying device (12) having a second signal variation profile to produce a cumulative signal variation profile that differs from the first and second signal variation profiles.</p> |
