PURPOSE:To obtain the structure of an optical receiver to facilitate the design and adjustment of a filter which respectively outputs a prescribed frequency band signal from an electrical signal photoelectrically converted by a photoelectrical transducing element independently without deteriorating the characteristic of the filter. CONSTITUTION:The filters 2, 3 having prescribed passing characteristic and outputting desired frequency band signals are respectively connected to the anode and cathode sides of the photoelectric transducing element 1 which converts a transmitted optical signal into the electrical signal independently. Especially, the filters 2, 3 connected independently are provided with finite output side terminating impedance. |
