    Abstract: PROBLEM TO BE SOLVED: To provide a wide optical wavelength (WDM) communication system whose loss is low, whose polarity dependency is low and which realizes compensation over wide band width by providing an adjustable multichannel dispersion compensating fiber whose loss is low, whose polarity dependency is low and which has a function capable of compensating many channels over a wide wavelength range. SOLUTION: This WDM optical fiber communication system 10 is provided with a multiple wavelength light transmitter 11, an optical fiber for transmission 12, and the adjustable multichannel dispersion compensating fiber 13 for compensating the dispersion of the optical fiber 12. The fiber 13 is provided with a variable partial reflector 19, a fixing mirror 29 and an optical cavity 27 arranged on an optical path between the reflector 19 and the mirror 29. On parallel side surface 28 and the mirror 29 regulate the optical cavity having thickness L. The thickness L is selected so that a free spectral range(FSR) may be the integral multiple of space between the optical channels of the system. Thus, many channels are simultaneously compensated.
