ABSTRACT An optical shunt device in which a pair of connecting ends for being connected to optical communication fiber sections are divided into three systems. The first of the three systems is a passing-through light conduction path through which light signals in two opposite directions are allowed to pass through between the connecting ends. The second of the three systems is a receiving light conduction path having a first light- receiving end and a second light-receiving end each receiving a light signal from the connecting ends . The third light path has a first light-transmitting end and a second light-transmitting end each transmitting a light signal to the connecting ends. The optical shunt device also comprises a photo-electric conversion unit including a light-receiving element disposed at the first and second light-receiving ends for receiving a light signal from the fist light- receiving end and the second light-receiving end of the second light path and converting it into an electric signal, an amplifier circuit for amplifying the electric signal from the light-receiving element , and a light-emitting element disposed at the first and second light-transmitting ends for converting the electric signal into an optical signal to supply the optical signal to the first and second light-transmitting ends.
