Abstract

PURPOSE: To relax remarkably the limitation in the transmission range and the operating wavelength region due to dispersion of an optical fiber by using an optical fiber bundle having a dispersion of opposite sign to that of the optical fiber so as to cancel the dispersion at each wavelength.
CONSTITUTION: A signal light in wavelength λ1∼λ5 irradiated from a semiconductor laser is collected and fed to optical fibers 11∼15, subject to wavelength multiplex at a light synthesis circuit 5 and led to an optical fiber 2. A wavelength multiplex at a light synthesis circuit 5 and led to an optical fiber 2. A wavelength multiplex signal propagated through the fiber 2 is multiplexed into a signal light of wavelength λ1∼λ5 and received by photodetectors 71∼75. Then, a signal sent at each wavelength is extracted from electric signal output terminals 81∼85. When the dispersion of the fiber 2 is MO(λi) and the length is LO, each dispersion Mi(λi) and each length Li of the fibers 11∼15 are set to satisfy Mii).Li=-MO(λi).Li. Thus, the dispersion of the fiber 2 is compensated b the fiber bundle 1.
