PURPOSE:To temporarily delay n-bit data by transmitting data by the combination of the position of the number of the wavelength band areas of an aphotic zone formed in communication light. CONSTITUTION:Communication light A transmitted to an optical fiber system light output part 12B is divided by the difference in reflectance among wavelengths by using a prism effect by a prism 14. Sensors 15 detect an aphotic zone B of the received communication light A, that is, a data signal is displayed on an output device 17 such as a display device and a printer through a receiving CPU 16 by a detection signal from a detection partition corresponding to the aphotic zone B among the detection partitions of partitions S0, S1, S2...S7 except aphotic zone existing area. The sensors 15 detects a receiving timing concerning the wavelength band areas by the auxiliary detection parts, namely, partitions S00, S01...S07, S0X except the aphotic zone existing area when receiving the communication light A. Thus, 2<n> (n: the number of aphotic zones) data can be transmitted. |
