Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission system that adopts a signal mode fiber system to avoid interference between a wavelength division multiplex WDM signal and an analog television TV signal. SOLUTION: This wavelength division multiplex system has a 1st multiplexer 112 that connects a plurality of digital information channels to a transmission path and the transmission path including an optical fiber 130 whose zero dispersion wavelength λ0 is 1310 nm and whose length exceeds a span to 10 km. The loss of the optical fiber at 1385 nm is smaller than the loss at 1310 nm, and color element dispersion at a 1.4 μm wavelength band is within a range of 1.5-8.0 ps/nm.km, and the 1st multiplexer 112 gives three or more channels of wavelength division multiplex signals within the 1.4 μm wavelength band to the transmission path.
