Abstract:
An optical transmission system including a laser transmitting device and a single mode transmission fiber, said fiber having a nominal zero-dispersion wavelength range of .lambda..sub.0 .+-..DELTA..lambda., .lambda..sub.0 being defined as the fiber zero dispersion wavelength and .DELTA..lambda. being defined as a predetermined, known variation of said fiber zero dispersion wavelength, wherein a system wavelength .lambda..sub.sys exhibits a negative dispersion-related power penalty and is selected from within a system wavelength range of .DELTA..lambda..sub.sys having an upper bound of .lambda..sub.0 -.DELTA..lambda. and a lower bound defined by the relation:lower bound=M(S*L)+(.lambda..sub.0 +.DELTA..lambda.),where M is defined as the maximum fiber negative dispersion value for which the dispersion power penalty is negative, S is defined as the dispersion slope of the single mode transmission fiber and L is defined as the transmission length of said single mode transmission fiber.
