OPTICAL COMMUNICATION SYSTEM AND ENDOSCOPE SYSTEM

摘要

A transmitting device includes: a first transmission unit; a second transmission unit having transmission lines each having a proximal end at which a transmitting-side connecting portion is provided; and a first switch for selecting a transmission line from the second transmission unit, to connect the selected transmission line to the first transmission unit. A receiving device includes: a third transmission unit having transmission lines each having a distal end at which a receiving-side connecting portion is provided; a fourth transmission unit; a second switch for selecting, from the third transmission unit, a transmission line including the receiving-side connecting portion optically connected to the transmitting-side connecting portion, to connect the selected transmission line to the fourth transmission unit; and a detection unit configured to detect whether a connection between the transmitting-side and receiving-side connecting portions is abnormal based on light amount of an optical signal transmitted through the fourth transmission unit.

1. An optical communication system comprising:
a transmitting device configured to transmit an optical signal; and a receiving device attachable to and detachable from the transmitting device and configured to receive the optical signal transmitted from the transmitting device, the transmitting device comprising:
a first optical transmission unit having a single optical transmission line to receive the optical signal;a second optical transmission unit having a plurality of optical transmission lines each having a proximal end at which a transmitting-side optical connecting portion is provided; anda first optical switch configured to select at least one optical transmission line from the second optical transmission unit, and to connect the at least one selected optical transmission line to the first optical transmission unit, and the receiving device comprising:
a third optical transmission unit having a plurality of optical transmission lines each having a distal end at which a receiving-side optical connecting portion is provided, the receiving-side optical connecting portion being optically connectable to the transmitting-side optical connecting portion, and the third optical transmission unit being configured to transmit the optical signal received from the receiving-side optical connecting portion;a fourth optical transmission unit having a single optical transmission line to transmit the optical signal;a second optical switch configured to select, from the third optical transmission unit, an optical transmission line including the receiving-side optical connecting portion connected to the transmitting-side optical connecting portion of the at least one optical transmission line selected from the second optical transmission unit by the first optical switch, and to connect the selected optical transmission line to the fourth optical transmission unit;a control unit configured to control switching between the optical transmission lines connected to the first optical switch, and to control switching between the optical transmission lines connected to the second optical switch; andan abnormality detection unit configured to detect whether or not a connection state between the transmitting-side optical connecting portion and the receiving-side optical connecting portion is abnormal based on light amount information of the optical signal transmitted through the fourth optical transmission unit by way of the optical transmission lines selected in accordance with switching control of the first optical switch and the second optical switch by the control unit.
