IPC: H01S3/067
Filed: 1991-02-04
Abstract: PURPOSE:To obtain constitution wherein the loss of a dispersed medium causes no deterioration in reception sensitivity while adding the dispersed medium which compensates the dispersion of a transmission line. CONSTITUTION:A receiver consisting of an optical amplifier OA and an O/E conversion part has its S/N as a receiver determined by an initial-stage optical amplifier OA and has higher sensitivity than reception by only the O/E. Further the level itself of an optical signal after optical amplification is not S/N- sensitive. For the purpose, the output level of the OA is set much higher than the reception sensitivity of the 0/E and then even when the dispersed medium is interposed between the OA and OE, the dispersion can be compensated without any influence upon the reception sensitivity.
