Title: Optical transmission system
Inventor: TANAKA HIROHITO
IPC: H04B10/25
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To suppress accumulated wavelength dispersion without a dispersion compensation fiber. SOLUTION: An optical transmission terminal station 10 outputs a signal light with a λ1 longer than a zero dispersion wavelength 20 of transmission optical fibers 16-1 to 16-3 to the transmission optical fiber 16-1. The signal light propagated through the transmission optical fiber 16-1 is made incident onto a wavelength converter 18-1. The wavelength converter 18-1 applies wavelength conversion to the incident signal light with the wavelength λ2 into a wavelength λ2 shorter than the zero dispersion wavelength λ1 and outputs it to the transmission optical fiber 16-2. The signal light propagated through the transmission optical fiber 16-2 is made incident onto a wavelength converter 18-2.  The wavelength converter 18-2 applies wavelength conversion to the incident signal light with a wavelength λ2 into the signal with the wavelength λ2 conversely to the case with the wavelength converter 18-1 and outputs the resulting signal to the transmission optical fiber 16-3.
