Filed: 1985-04-04
Abstract: PURPOSE:To attain simply the extension of an input/output station without requiring an optical fiber connecting work by connecting a control section extended newly to an optoelectric and electrooptic conversion circuit excluded from the connection with an intra-office control section so as to fetch an optical signal passing through an input/output station. CONSTITUTION:The content of an optical signal is wavelength lambda2 having only to pass through an IOSI-S simply is converted into an electric signal by an O/E2 and inputted to a control section S'. The control section 4S' checks the transmission destination address of the said signal and when the signal is addressed to the own station, the signal is fetched and when not addressed to the own station, to signal is outputted to the E/02. Then the E/02 converts the signal into an optical siganl in a wavelength lambda2 and the result is sent to a next station [IOSI-(s+1)] via an optical synthesis branching filter and a line. This is applied similary when the control section 4S' makes transmission voluntly.
