12 Nonlinear Processes in Optical Fibers
Fig. 12.4 SRS transfers
optical power from shorter
wavelengths to longer
wavelengths
Fig. 12.5 Simplified linear
approximation for the
Raman gain coefficient as a
function of channel spacing
with a low-value decaying
tail at channel separations
greater than 16 THz
from a lower-wavelength channel to a higher-wavelength channel increases approximately linearly with channel spacing up to a maximum of about c = 16 THz
(or c = 125 nm in the 1550 nm window), and then drops off sharply for larger
spacings.
