Abstract

PURPOSE:To simply constitute the system transmission system, by the light emitting section which can change the wave length emitted, and the optical filter which can pick up the light of specific wave length only from the transmission line. CONSTITUTION:The signal light from the light emission section 1 which can change the wave length emitted is transmitted to either one of the photodetection sections 2, 3, or 4 through the optical fibers 5, 6, 7, 8, 12, 13, 14 and the optical filters 9, 10, 11. For example, in case of transmission to the photodetection section 3, the wave length of light emission of the light emission section 1 is made in agreement with the wave length lambda2 of the optical filter 10, allowing to pass the light in the filter 9 without loss and to transmit the signal only to the photodetection section 3. Accordingly, since the opposing party can be switched and selected by changing the wave length of the light emission section only, the transmission system can simply be constituted.
