WebbThe information capacity of a linear channel with additive white Gaussian noise (AWGN) is often called the Shannon limit, stressing the fact that it is the maximum error-free data … WebbAbstract We extend the Shannon information theory to a nonlinear system and present a model for calculating the channel capacity of an optical-fiber transmission system using dispersion-free fiber. For this particular fiber,a closed-form solution for the nonlinear Schroedinger equation exists.
Webbtechnique. The bandwidth in the optical fiber is limit ed by the intrinsic loss of light propagating through silica. The maximum bandwidth is considered to be 50 THz (1.2 P m – 1.6 P m), because of the spacing of standard frequency grids. Actually, the optical communication systems have a bandwidth limited to about 15 THz.
